The codebase demonstrates professional security implementation including:\n\n✅ Comprehensive path validation with symlink resolution \n✅ Strict directory access control via allowlist \n✅ Atomic file operations preventing race conditions \n✅ Proper handling of null bytes and path traversal attempts \n✅ Detailed security comments explaining design decisions \n\nThe 2 low-severity findings are minor improvements that don't represent exploitable vulnerabilities.\n\n### Real Findings (2 low-severity issues)\n\n#### 1. LOW: Error messages expose internal path information\n**File:** `src/filesystem/lib.ts:87` \n**Issue:** Error messages include full filesystem paths when validation fails \n**Impact:** Could leak directory structure in shared environments \n**Remediation:** Consider sanitizing error messages in production mode\n\n#### 2. LOW: NPX usage without version pinning in documentation \n**File:** `README.md:243` \n**Issue:** Documentation shows `npx -y @modelcontextprotocol/server-filesystem` without version pinning \n**Impact:** Supply chain risk if malicious version published \n**Remediation:** Update docs to recommend version pinning for production: `npx -y @modelcontextprotocol/server-filesystem@0.6.3`\n\n### By-Design Security Patterns (Informational)\n\nThese are intentional features that require careful user configuration but are not vulnerabilities:\n\n1. **Broad filesystem permissions** - By design for an MCP filesystem server. Users control allowed directories via configuration.\n2. **Arbitrary path operations** - Necessary functionality for AI agent file operations. Protected by path validation.\n\n### Recommendations\n\n1. **For Documentation:** Add version pinning examples to README\n2. **For Error Handling:** Implement a debug mode flag to toggle verbose vs. sanitized errors\n3. **For Users:** Always restrict allowed directories to minimum necessary paths; use Docker read-only mounts where possible\n\n### Full Report\n\nView the complete audit report with code-level details and evidence: \n**[AgentAudit Report](https://agentaudit.dev/skills/mcp-server-filesystem)**\n\n---\n\n*This audit was performed automatically by [AgentAudit](https://agentaudit.dev), the security registry for AI agent packages.

While this is user-configured and not externally exploitable, relative paths with '../' sequences could potentially write outside the intended directory. However, this is a configuration-time setting controlled by the user, not runtime input from external sources.\n\n**Affected Code:**\n```javascript\n: path.join(path.dirname(fileURLToPath(import.meta.url)), process.env.MEMORY_FILE_PATH);\n```\n\n**Remediation:** Consider validating that resolved paths don't escape the intended directory, or require absolute paths only. Alternatively, document that users should use absolute paths for MEMORY_FILE_PATH.\n\n### Full Report\n\nView the complete audit report with details, evidence, and remediation guidance:\n**[AgentAudit Report](https://agentaudit.dev/skills/@modelcontextprotocol/server-memory)**\n\n---\n\n*This audit was performed automatically by [AgentAudit](https://agentaudit.dev), the security registry for AI agent packages.

server that gives AI agents \"X-ray vision\" into compiled Java code. It enables LLMs to decompile and analyze Java classes from Maven/Gradle dependencies, solving a critical pain point for Java developers using AI assistants.\n\n## Project Details\n\n- **Name**: jarp-mcp (Java Archive Reader Protocol)\n- **GitHub Repository**: https://github.com/tersePrompts/jarp-mcp\n- **Package**: https://www.npmjs.com/package/jarp-mcp\n- **License**: Apache-2.0\n- **Language**: TypeScript 5.7 / Node.js 16+\n- **MCP Version**: Compatible\n\n## Problem It Solves\n\nAI agents like Claude, GPT-4, and Cursor **cannot read compiled Java code**. When working with Spring Boot, Maven, or any Java project:\n\n- *\"Show me how JpaRepository.saveAll() works\"* → Agent **hallucinates** the method signature\n- *\"What parameters does this internal library function take?\"* → Agent **guesses** wrong\n- *\"Why does this dependency throw this exception?\"* → Agent **cannot see** the source\n\nDevelopers typically spend 5-10 minutes per class manually decompiling with JD-GUI, copying source, and pasting into chat.\n\n## Installation\n\n### Zero-Setup (Recommended)\n\n\\`\\`\\`bash\nnpx jarp-mcp\n\\`\\`\\`\n\nNo installation required. The CFR decompiler is bundled.\n\n### Global Install\n\n\\`\\`\\`bash\nnpm install -g jarp-mcp\njarp-mcp start\n\\`\\`\\`\n\n## MCP Configuration\n\nAdd to your AI editor's MCP configuration (Claude Desktop, Cursor, Windsurf, Cline, etc.):\n\n\\`\\`\\`json\n{\n \"mcpServers\": {\n \"jarp-mcp\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"jarp-mcp\"]\n }\n }\n}\n\\`\\`\\`\n\n## MCP Tools Provided\n\n| Tool | Description |\n|------|-------------|\n| **\\`scan_dependencies\\`** | Scans Maven/Gradle project, builds class → JAR index |\n| **\\`decompile_class\\`** | Returns full Java source code for any class |\n| **\\`analyze_class\\`** | Analyzes class structure, methods, fields, inheritance |\n\n## Key Features\n\n- **Zero external dependencies** — CFR decompiler bundled (2.2MB JAR)\n- **Smart path resolution** — Works with \\`npx\\`, \\`npm install -g\\`, local dev\n- **Maven & Gradle support** — Parses \\`pom.xml\\` and \\`build.gradle\\`\n- **Intelligent caching** — First decompile ~2s, subsequent <100ms\n- **Auto-indexing** — Builds class index on-demand if missing\n- **Cross-platform** — Works on Windows, macOS, Linux\n\n## Performance\n\n| Operation | First Run | Cached |\n|-----------|-----------|--------|\n| Scan 100 JARs | ~30s | N/A |\n| Decompile class | ~2s | <100ms |\n| Analyze structure | ~2s | <100ms |\n\n**Real-world example**: Spring Boot project with 156 dependencies (12,458 classes)\n- Initial scan: 45 seconds\n- Each class: ~1.5s first time, instant thereafter\n\n## Tech Stack\n\n\\`\\`\\`\nLanguage: TypeScript 5.7\nRuntime: Node.js 16+\nProtocol: Model Context Protocol (MCP)\nDecompiler: CFR 0.152 (bundled)\nBuild: tsc\nPackage: npm (zero-setup with npx)\nLicense: Apache-2.0\n\\`\\`\\`\n\n## Impact\n\n| Metric | Before | After |\n|--------|--------|-------|\n| Time to inspect a class | **5-10 min** | **<2 seconds** |\n| Accuracy of AI responses | ~60% (guessing) | **100%** (actual source) |\n| Manual steps | 4+ | **0**

When a user specifies `/tmp` as allowed and passes `/tmp/foo.txt`, the server resolves it to `/private/tmp/foo.txt`, which doesn't match the allowed path `/tmp`.\n\n## Reproduction Steps\n\n1. Start server-filesystem with `/tmp` as allowed directory:\n ```bash\n npx -y @modelcontextprotocol/server-filesystem /tmp\n ```\n\n2. Call `read_file` with a path under `/tmp`:\n ```json\n {\"path\": \"/tmp/test.txt\"}\n ```\n\n3.

This ensures consistent comparison with resolved request paths.\n\n---\n\n## Discovery\n\nThis bug was discovered using **[Bellwether](https://github.com/dotsetlabs/bellwether)**, a structural drift detection and behavioral testing tool for MCP servers.

Once this is available in a released SDK version, we can upgrade to full HTTP elicitation support.\n\n## Changes needed\n\n1. Update `@modelcontextprotocol/sdk` dependency to version with streaming elicitation\n2. Replace try-catch `sendRequest` pattern with streaming API in `simulate-research-query.ts`\n3.

works on all platforms including Windows\n await fs.cp(tempPath, filePath, { force: true });\n} finally {\n try {\n await fs.unlink(tempPath);\n } catch {}\n}\n```\n", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3199/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [ 3296 ] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3198", "id": 3800084277, "node_id": "I_kwDONRaG_87igK81", "number": 3198, "title": "feat: Add block-no-verify to prevent AI agents from bypassing git hooks", "user": { "login": "tupe12334", "id": 61761153, "node_id": "MDQ6VXNlcjYxNzYxMTUz", "avatar_url": "https://avatars.githubusercontent.com/u/61761153?v=4", "gravatar_id": "", "url": "https://api.github.com/users/tupe12334", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": {}, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2026-01-10T17:13:23Z", "updated_at": "2026-01-10T17:13:23Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "## Summary\n\nAdd the [`block-no-verify`](https://www.npmjs.com/package/block-no-verify) package to prevent AI coding agents from bypassing git hooks using the `--no-verify` flag.\n\n## Problem\n\nAI coding agents (Claude Code, Gemini CLI) can bypass pre-commit hooks by running `git commit --no-verify`, which defeats the purpose of code quality checks enforced by git hooks.\n\n## Proposed Solution\n\nIntegrate `block-no-verify` (v1.1.1) which:\n- Monitors git commands (`commit`, `push`, `merge`, `cherry-pick`, `rebase`, `am`)\n- Blocks execution when `--no-verify` or `-n` flag is detected\n- Supports both Claude Code and Gemini CLI\n\n### Configuration Required\n\n**For Claude Code** - Create `.claude/settings.json`:\n```json\n{\n \"hooks\": {\n \"PreToolUse\": [\n {\n \"matcher\": \"Bash\",\n \"hooks\": [\n {\n \"type\": \"command\",\n \"command\": \"npx block-no-verify\"\n }\n ]\n }\n ]\n }\n}\n```\n\n**For Gemini CLI** -

file that contains an entity with properties not defined in the official schema (`name`, `entityType`, `observations`). This creates an inconsistency where the server can store data that the client-side validation for `read_graph` will later reject, making it impossible to retrieve the stored memory.\n\n### To Reproduce\n\nSteps to reproduce the behavior:\n1. Start the `@modelcontextprotocol/server-memory`.\n2. Ensure the `memory.jsonl` file contains at least one entity object with an extra, non-standard property. For example:\n ```json\n {\"name\": \"Test_Entity\", \"entityType\": \"test\", \"observations\": [\"Has an extra field\"], \"custom_id\": \"xyz-123\"}\n ```\n3. Use any MCP client (e.g., the VS Code extension) to execute the `read_graph` tool.\n4. Observe that the tool execution fails.\n\n### Expected behavior\n\nThe `read_graph` tool should successfully execute without a fatal error. It should handle entities with extra properties gracefully, ideally by ignoring the non-standard properties and returning only the schema-defined fields (`name`, `entityType`, `observations`) for each entity. The presence of extra data in the storage file should not prevent the core functionality of reading the graph.\n\n### Logs\n\nThe following error is returned by the client when the bug occurs:\n\n```\nError: McpError: MCP error -32602: Structured content does not match the tool's output schema: data/entities/0 must NOT have additional properties\n```\n\n### Additional context\n\nThis bug highlights a discrepancy between the data persistence logic and the data retrieval/validation logic. To resolve this, I suggest two potential approaches:\n\n* **Make the schema more flexible:** Allow additional properties in the client-side schema validation for `read_graph`. This would make the tool more robust.\n* **Enforce strictness on write:** Actively strip or reject any non-standard properties during entity creation (`create_entity`) to ensure the integrity of the `memory.jsonl` file.\n\nOption 1 seems preferable as it adds flexibility and prevents data retrieval failures.", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3144/reactions", "total_count": 2, "+1": 2, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [ 3161 ] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3137", "id": 3741903809, "node_id": "I_kwDONRaG_87fCOvB", "number": 3137, "title": "Memory MCP `open_nodes` returns empty relations array despite entity having relations in graph", "user": { "login": "broboa", "id": 216722296, "node_id": "U_kgDODOrreA", "avatar_url": "https://avatars.githubusercontent.com/u/216722296?v=4", "gravatar_id": "", "url": "https://api.github.com/users/broboa", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 1, "created_at": "2025-12-18T07:55:55Z", "updated_at": "2025-12-18T09:56:47Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Describe the bug**\n\nThe `open_nodes` tool returns an empty `relations` array even when the requested entity has outgoing relations in the knowledge graph. This makes it impossible to traverse the graph from a specific node without calling `read_graph` and filtering the entire dataset client-side.\n\n**To Reproduce**\n\n1. Create two entities and a relation between them:\n```javascript\ncreate_entities({\n entities: [\n { name: \"2025-12-17\", entityType: \"work-day\", observations: [] },\n { name: \"incident/example\", entityType: \"incident\", observations: [\"Test incident\"] }\n ]\n})\n\ncreate_relations({\n relations: [{\n from: \"2025-12-17\",\n to: \"incident/example\",\n relationType: \"worked-on\"\n }]\n})\n```\n\n2. Call `open_nodes` on the source entity:\n```javascript\nopen_nodes({ names: [\"2025-12-17\"] })\n```\n\n3. Observe the result has an empty `relations` array\n\n**Expected behavior**\n\n`open_nodes` should return outgoing relations from the requested entity, similar to how graph databases return edges when querying a node. The response should include:\n\n```json\n{\n \"entities\": [\n {\n \"type\": \"entity\",\n \"name\": \"2025-12-17\",\n \"entityType\": \"work-day\",\n \"observations\": []\n }\n ],\n \"relations\": [\n {\n \"type\": \"relation\",\n \"from\": \"2025-12-17\",\n \"to\": \"incident/example\",\n \"relationType\": \"worked-on\"\n }\n ]\n}\n```\n\n**Logs**\n\nActual response from `open_nodes`:\n```json\n{\n \"entities\": [\n {\n \"type\": \"entity\",\n \"name\": \"2025-12-17\",\n \"entityType\": \"work-day\",\n \"observations\": []\n }\n ],\n \"relations\": []\n}\n```\n\nCalling `read_graph` confirms the relation exists in the graph.\n\n**Additional context**\n\nThis limitation forces users to call `read_graph` (which returns the entire knowledge graph) and filter client-side to find relations for specific entities. This doesn't scale as the graph grows.\n\nUse case: Daily work tracking where date entities link to topic entities via `worked-on` relations. To generate a daily summary for a specific date, we need to find all topics linked from that date, but `open_nodes` doesn't provide this information.\n\nSuggested solutions:\n1. Include both incoming and outgoing relations in `open_nodes` response by default\n2.

Please describe.**\nI want to host a public filesystem MCP via HTTPS, by installing it into a docker container, together with other stuff that users won't be interested in. I'd like a way to specify which directories users can see and access.\n\n`docs/docs/learn/client-concepts.mdx` says that roots are mere hints:\n\n> Roots work best when […] users understand their advisory nature, and the goal is preventing accidents rather than stopping malicious behavior.\n\nIn my case it wouldn't even necessarily be malicious, but when users would want to see \"all files on that MCP\" they'd probably give `/` as the root, and would be confused to see the entire docker container. Also their AI might be confused about the vast amount of unexpected boring files. They'd have expected to only see the directories with my actual intended content, which would be `/pubfiles/` in my docker container.\n\n`src/filesystem/README.md` says about \"Roots Protocol Handling\":\n\n> Server replaces ALL allowed directories with client's roots\n\nNote it says \"allowed\". That sounds like a mixup of the concepts of a client's declaration of intent about what to use, vs. a server operator's intent about what to share. In a similar manner, the\n\n> Note: The server will only allow operations within directories specified either via args or via Roots.\n\nlacks explanation why something that the server operator can decide (command arguments) should be handled equivalent to something that arbitrary users can send (roots).\n\n**Describe the solution you'd like**\n* Server operators can configure a base directory that will become the top level for all roots, i.e. it would be `file:///` in the root URLs namespace.\n* Inside that, server operators can configure \"allowed\" directories, and only those (and their parent directories) will be visible and accessible.\n * In the trivial case, this is a single entry `/` for the top level.\n * Default is still the empty list = no access at all, to avoid accidents when people comment-out the last entry in their config.\n * The idea behind this feature is so I can easily expose the `photos`, `books`, and `videos` subdirectories of my `/pubfiles`, but not confuse users' AI with all the stuff in `/pubfiles/.git` and `/pubfiles/.cache`.\n* When a client has no roots support, assume it wants to see everything, i.e. act as if it had specified a single root with URI `file:///`\n* When roots are received, track them as \"intended\" directories, i.e. a voluntary additional restriction of the \"allowed\" directories. Any roots outside of the \"allowed\" directories is simply ignored, pretending the directory doesn't exist.\n* There should be an option about which kinds of symlinks to accept along the way: `none` = none (default), `same-owner` = symlink must be owned by the same user and group as its target, `trust-all` = yolo. For unacceptable symlinks, pretend they don't exist. (Not sure if that should be its own feature request issue.)\n\n**Describe alternatives you've considered**\n\n\n**Additional context**\nI'm hosting the server publicly because parts of my audience won't be able to install their own MCP-related software.

The error is triggered when a client or server attempts to read a directory as if it were a file and fails with Node's EISDIR error.\n\nEnvironment\n\n- Node: 24.x (example from workspace: v24.11.1)\n- npx: 11.x\n- Memory server: `@modelcontextprotocol/server-memory`\n- Workspace: firstb00t-v2 (project-level analysis performed on: /Users/nmn/rez0/neimen/0-code/github-pun/firstb00t-v2)\n\nReproduction steps (simplified)\n\n1. Stop the memory server or ensure it is unreachable.\n2. From a client (or wrapper) call the memory MCP API `create_entities` or `add_observations` with an entity name that maps to an existing directory (e.g., `.github`) while not explicitly specifying `entityType` or specifying `entityType` incorrectly as `file`.\n3. If the client attempts to read the path or infers the path as a file, `fs.readFile` will be invoked and an `EISDIR` error occurs: `EISDIR: illegal operation on a directory, read `.\n\nObserved\n\n- Error message from Node: `EISDIR: illegal operation on a directory, read `.\n- The memory creation calls can partially succeed or fail — leading to inconsistent memory graph state.\n\nExpected\n\n- The MCP memory server or client should clearly handle directories and files separately.\n - For directories, either create an entity with `entityType: \"folder\"` or return a descriptive validation error asking the user to provide `entityType: \"folder\"`.\n - For files, accept the request and, when specified, read file contents or add string observations without implicit filesystem reads.\n- The client should not attempt to fallback to local filesystem reads when the memory server is offline; instead, return a connection error.\n\nPotential root causes\n\n- Client wrapper calls may attempt to read local file content automatically if a path-like `name` was provided (and entityType is not provided), and `fs.readFile` is invoked on a directory.\n- Server-side may accept `name` as a raw string without proper validation or safe handling of directories vs. files.\n- Server might accept wrong `entityType` values and not warning clearly.\n\nSuggested fixes\n\n1. Server-side validation\n - Validate the `entityType` upon /create_entities call and return clear, descriptive errors.\n - If `entityType` is not provided, return a validation error rather than attempting to infer a file read.\n2. Client-side helper\n - Add a client wrapper that uses `fs.stat()` to check path type before any reads. If `stat.isDirectory()` return `entityType: \"folder\"` or raise a validation error.\n - If the server is offline, return a connection error and avoid falling back to local file reads.\n3. Better logging\n - Add a more descriptive error message that indicates a directory path was provided and that a folder entity is required if that is intended.\n4. Tests\n - Add unit/integration tests to validate behavior of both file & folder `entityType` creation, including offline server test to ensure no local file reads occur.\n\nAttachments (from local analysis)\n\n- `.context/eisdir_analysis.md` — local analysis of root cause for EISDIR error.\n- `.context/mem_import_2025-11-28.json` — audit of entities & relations created while testing.\n- `.context/filetree.md` — canonical file tree with clear folder/file separation.\n\nNotes\n\n- I can open a PR to add a client-side wrapper and tests if you want.

The server includes the `type` field in entity objects when reading from file, but the output schema does not allow this field.\n\n## Environment\n\n- **Server**: `@modelcontextprotocol/server-memory`\n- **Version**: `2025.11.25` (latest available)\n- **OS**: Linux Ubuntu 24.04\n- **MCP Client**: Cursor IDE\n\n## Steps to Reproduce\n\n1. Configure Memory MCP server with a JSONL format `memory.json` file\n2. File contains entities with structure: `{\"type\":\"entity\",\"name\":\"...\",\"entityType\":\"...\",\"observations\":[...]}`\n3. Call any read operation:\n - `mcp_memory_read_graph`\n - `mcp_memory_search_nodes`\n - `mcp_memory_open_nodes`\n4. All operations fail with the same error\n\n## Expected Behavior\n\nRead operations should return entities without the `type` field, as entities are already separated in the response structure (`data.entities` vs `data.relations`).\n\n## Actual Behavior\n\nAll read operations return error:\n```json\n{\n \"error\": \"MCP error -32602: Structured content does not match the tool's output schema: data.entities[0] should NOT have additional properties\"\n}\n```\n\nNo partial data is returned - the response contains only the error field.\n\n## Technical Details\n\n- **File format**: JSONL (newline-delimited JSON)\n- **Total lines**: 538\n- **Entities**: 206\n- **Relations**: 332\n- **Entity schema in file**: `{type, name, entityType, observations}` (4 fields)\n- **Expected entity schema in output**: `{name, entityType, observations}` (3 fields, no `type`)\n\nThe `type` field is necessary in the file to distinguish entities from relations, but should be stripped when preparing the response.\n\n## Workaround\n\n- Read data directly from `memory.json` file using file I/O\n- Write operations (`create_entities`, `add_observations`, etc.) work correctly\n- Only read operations are affected\n\n## Additional Information\n\n- The file structure is valid and can be read successfully using direct file access\n- The issue appears to be in the server's schema validation logic\n- Cache cleared (`npm cache clean --force`) but issue persists\n- Issue occurs with latest server version (2025.11.25)\n\n## Error Code\n\n`MCP error -32602` - Invalid params / Schema validation

Errors” warning for a test that intentionally throws an error (\"should throw error for non-existent entity\").\nThe test itself passes correctly using .rejects.toThrow(), but Vitest incorrectly surfaces the expected rejection as an unhandled error.\n\nThis causes the TypeScript / Test memory CI job to fail even though there is no bug in the memory server implementation.\n\nTo Reproduce\n\nSteps to reproduce the behavior:\n\nRun the memory server tests using:\n\npnpm test:memory\n\n\nLook for the test:\n\n\"should throw error for non-existent entity\"\n\nObserve that the test passes but Vitest outputs an “Unhandled Errors” warning.\n\nIn GitHub Actions, this warning results in a failing test job.\n\nExpected behavior\n\nVitest should correctly treat .rejects.toThrow() as a handled and expected error, and should not report the intentionally thrown error as an unhandled rejection.\n\nCI should pass when the test succeeds, without false-positive warnings.\n\nLogs\n\nExample output:\n\nUnhandled Errors:\n ❯ Error: Entity does not exist\n at ...\n\n\nThe test reports PASS\n\nThe warning appears only in the \"Unhandled Errors\" summary\n\nNo runtime errors or implementation failures occur\n\nAdditional context\n\nThis behavior is a Vitest testing quirk, not a bug in the memory server code.\n\nAll locking, file serialization, and race condition tests pass successfully.\n\nThe new lock implementation is functioning as expected.\n\nThe false warning appears because Vitest sometimes logs expected async errors as “unhandled” even when wrapped in .rejects.toThrow().\n\nPossible mitigations (optional):\n\nRewrite the test using assert.rejects(...)\n\nWrap error tests to avoid Vitest’s unhandled rejection reporting\n\nAdd scoped process.on(\"unhandledRejection\", () => {}); for this file (not recommended except for CI cleanliness)\n\nIf you want, I can also rewrite the test file for a clean CI run.", "closed_by": null,

URL: https://modelcontextprotocol.io/mcp\n - Description: Official MCP protocol documentation\n - Type: Remote server\n - Transport: Streamable HTTP\n\n## Registration Process\n\nBased on the [MCP Registry documentation](https://github.com/modelcontextprotocol/registry/tree/main/docs/modelcontextprotocol-io), here's the workflow:\n\n### Prerequisites\n\n- [ ] Install mcp-publisher CLI tool\n ```bash\n # macOS/Linux - see https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx for exact command\n # Windows - see registry docs for PowerShell command\n ```\n- [ ] Ensure packages are published to npm/PyPI\n- [ ] GitHub account for authentication\n\n### For Each Server\n\n**See the [Publisher Quickstart](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx) for the complete official process.**\n\n1. **Update Package Metadata**\n - NPM: Add `mcpName` property to package.json (must match server name in server.json)\n - PyPI: Add `mcp-name: $SERVER_NAME` to README (can be in HTML comment)\n\n2. **Verify Package Publication**\n - Ensure latest version is published to npm/PyPI\n - Confirm package is publicly accessible\n\n3. **Create server.json**\n ```bash\n cd src/[server-name]\n mcp-publisher init\n ```\n Follow the interactive prompts to generate the file. The tool will create the correct structure.\n\n4. **Authenticate**\n ```bash\n mcp-publisher login github\n ```\n - Follow GitHub device flow\n - Must authenticate as `modelcontextprotocol` organization member\n\n5. **Publish to Registry**\n ```bash\n mcp-publisher publish\n ```\n\n6. **Verify Registration**\n - Check https://registry.modelcontextprotocol.io/\n - Search for the server by name\n\n## Technical Requirements\n\n### NPM Packages\n\n**Required Changes to package.json:**\n\nThe `mcpName` property **MUST** match the server name from `server.json`.\n\n```json\n{\n \"mcpName\": \"io.github.modelcontextprotocol/server-everything\",\n \"repository\": {\n \"type\": \"git\",\n \"url\": \"https://github.com/modelcontextprotocol/servers.git\"\n }\n}\n```\n\n**Reference**: [Package Types - npm](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/package-types.mdx#npm-packages)\n\n### PyPI Packages\n\n**Required Addition to README.md:**\n\nThe README must contain an `mcp-name: $SERVER_NAME` string where `$SERVER_NAME` **MUST** match the server name from `server.json`. This can be placed in an HTML comment:\n\n```markdown\n\n```\n\nOr as plain text near the top of the README.\n\n**Reference**: [Package Types - PyPI](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/package-types.mdx#pypi-packages)\n\n### server.json Templates\n\n**Note**: Use `mcp-publisher init` to generate the correct structure. The examples below are for reference.\n\n**Reference**: [Publisher Quickstart - server.json structure](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx)\n\n#### For Package-based Servers (NPM/PyPI)\n\n```json\n{\n \"$schema\": \"https://static.modelcontextprotocol.io/schemas/2025-10-17/server.schema.json\",\n \"name\": \"io.github.modelcontextprotocol/server-[name]\",\n \"description\": \"Server description here\",\n \"repository\": {\n \"url\": \"https://github.com/modelcontextprotocol/servers\",\n \"source\": \"github\"\n },\n \"version\": \"0.6.x\",\n \"packages\": [{\n \"registryType\": \"npm\",\n \"identifier\": \"@modelcontextprotocol/server-[name]\",\n \"version\": \"0.6.x\",\n \"transport\": {\n \"type\": \"stdio\"\n }\n }]\n}\n```\n\n**For PyPI packages**, change:\n- `\"registryType\": \"pypi\"`\n- `\"identifier\": \"mcp-server-[name]\"`\n\n#### For Remote Servers\n\n```json\n{\n \"$schema\": \"https://static.modelcontextprotocol.io/schemas/2025-10-17/server.schema.json\",\n \"name\": \"io.github.modelcontextprotocol/docs\",\n \"description\": \"Official MCP protocol documentation\",\n \"repository\": {\n \"url\": \"https://github.com/modelcontextprotocol/servers\",\n \"source\": \"github\"\n },\n \"version\": \"1.0.0\",\n \"remotes\": [{\n \"url\": \"https://modelcontextprotocol.io/mcp\",\n \"type\": \"streamable-http\"\n }]\n}\n```\n\n**Reference**: [Remote Servers Documentation](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/remote-servers.mdx)\n\n## Detailed Checklist\n\n### 1. everything (NPM)\n\n- [ ] Add `mcpName` to src/everything/package.json\n- [ ] Verify npm publication status\n- [ ] Run `mcp-publisher init` in src/everything/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 2. filesystem (NPM)\n\n- [ ] Add `mcpName` to src/filesystem/package.json\n- [ ] Verify npm publication status\n- [ ] Run `mcp-publisher init` in src/filesystem/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 3. memory (NPM)\n\n- [ ] Add `mcpName` to src/memory/package.json\n- [ ] Verify npm publication status\n- [ ] Run `mcp-publisher init` in src/memory/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 4. sequentialthinking (NPM)\n\n- [ ] Add `mcpName` to src/sequentialthinking/package.json\n- [ ] Verify npm publication status\n- [ ] Run `mcp-publisher init` in src/sequentialthinking/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 5. fetch (PyPI)\n\n- [ ] Add `mcp-name:` marker to src/fetch/README.md\n- [ ] Verify PyPI publication status\n- [ ] Run `mcp-publisher init` in src/fetch/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 6. git (PyPI)\n\n- [ ] Add `mcp-name:` marker to src/git/README.md\n- [ ] Verify PyPI publication status\n- [ ] Run `mcp-publisher init` in src/git/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 7. time (PyPI)\n\n- [ ] Add `mcp-name:` marker to src/time/README.md\n- [ ] Verify PyPI publication status\n- [ ] Run `mcp-publisher init` in src/time/\n- [ ] Review generated server.json\n- [ ] Authenticate with GitHub (if needed)\n- [ ] Run `mcp-publisher publish`\n- [ ] Verify in registry\n\n### 8. docs (Remote Server)\n\n- [ ] Create server.json with remote configuration\n -

These could potentially be registered as OCI packages using the `io.modelcontextprotocol.server.name` annotation in Dockerfiles.\n\n**Reference**: [Package Types - Docker/OCI Images](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/package-types.mdx#dockeroci-images)\n\n### Special Considerations\n- Documentation server (docs) is registered as a remote server using the streamable HTTP transport\n- Remote servers **MUST** be publicly accessible at their specified URL (per [Remote Servers docs](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/remote-servers.mdx))\n- The `remotes` and `packages` properties can coexist in the same server.json, allowing users to choose their preferred installation method\n- Some servers support multiple transports; these can be registered with multiple entries in the `packages` or `remotes` arrays\n\n## Next Steps\n\n1. Install mcp-publisher CLI tool\n2. Authenticate with GitHub as modelcontextprotocol org member\n3. Work through checklist for each server\n4. Document any issues or special cases encountered\n5.

This differs from standard git behavior and creates portability issues:\n\n1. **Breaks when invoked from subdirectories**: If the MCP client is launched from a subdirectory of the repository, `--repository .` points to that subdirectory instead of the repository root, causing failures.\n\n2. **Forces absolute paths**: Teams must use absolute paths in configuration, requiring each developer to maintain local overrides since everyone has different clone paths.\n\n## Current Behavior\n\n```json\n{\n \"mcpServers\": {\n \"git\": {\n \"command\": \"uvx\",\n \"args\": [\n \"mcp-server-git\",\n \"--repository\",\n \".\"\n ]\n }\n }\n}\n```\n\nThis only works when the MCP client is launched exactly from the repository root.\n\n## Proposed Solution: Make `.` Auto-detect Repository Root (Preferred)\n\nWhen `--repository .` is specified, `mcp-server-git` should automatically search upward from the current directory to find the git repository root, just like standard git commands do.\n\n**Implementation:** Use `git rev-parse --show-toplevel` to find the repository root when the specified path is `.` or any path within a git repository.\n\n**Benefits:**\n- **Matches standard git behavior**: Every git command (git status, git log, etc.) works from anywhere inside the repository\n- **Zero configuration changes needed**: Existing configurations with `--repository .` would just work better\n- **Team-friendly**: Shared configuration works for all developers regardless of:\n - Which subdirectory they're working in\n - Where they cloned the repository\n - Which OS they're using\n\n## Alternative Solutions (Less Preferred)\n\n### Option 2: Environment Variable Expansion\nAllow `--repository \"${GIT_REPO_ROOT}\"` but this still requires configuration and environment setup.\n\n### Option 3: New Flag\nAdd `--auto-detect-root` flag, but this breaks existing configurations and is less intuitive than making `.` work naturally.\n\n## Use Case\n\nWe maintain a large IaC repository (~1000 files) with multiple subdirectories (`terraform/`, `applications/`, etc.). Team members work in specific subdirectories, and the current behavior forces us to either:\n- Always launch the MCP client from root (inconvenient)\n- Maintain per-developer absolute paths in local config files (maintenance burden)\n\nStandard git commands work perfectly from any subdirectory—`mcp-server-git` should too.\n\n## Comparison with Standard Git Behavior\n\n```bash\n# These work from ANY subdirectory within a git repo:\ncd /path/to/repo/terraform/environments/production\ngit status # ✅ Works - finds repo root automatically\ngit log # ✅ Works - finds repo root automatically\n\n# But mcp-server-git with --repository . does NOT:\nmcp-server-git --repository . # ❌ Uses CWD literally, doesn't find repo root\n```\n\nWould be happy to contribute a PR for this!", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3029/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/3013", "id": 3632728291, "node_id": "I_kwDONRaG_87Yhwjj", "number": 3013, "title": "create_relations and add_observations failing WSL2 VSCode", "user": { "login": "davidw-philips", "id": 223673186, "node_id": "U_kgDODVT7Yg", "avatar_url": "https://avatars.githubusercontent.com/u/223673186?v=4", "gravatar_id": "", "url": "https://api.github.com/users/davidw-philips", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-11-17T10:36:37Z", "updated_at": "2025-11-17T10:36:37Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Describe the bug**\nI'm using VSCODE copilot 4.5 with a custom Agent mode.\n\n**To Reproduce**\nSteps to reproduce the behavior:\n\nFor add_observations \n\nInput:\n{\n \"observations\": [\n {\n \"entityName\": \"project\",\n \"contents\": [\n \"Implemented\",\n \"Status system modules: \",\n \"Status states: CANCELLED\",\n \"All 30 unit tests passing for functionality\",\n \"Progress bar\",\n \"System designed\"\n ]\n }\n ]\n}\n\nOutput: \nError: MPC -32603: Unexpected non-whitespace character after JSON at position 127 (line 1 column 128)\n\n\nFor create_entities\n\nInput: \n{\n \"relations\": [\n {\n \"from\": \"framework project\",\n \"to\": \"Implementation\",\n \"relationType\": \"implements\"\n }\n ]\n}\n\nOutput:\nError: MPC -32603: Unexpected non-whitespace character after JSON at position 127 (line 1 column 128)\n\n**Expected behavior**\nA clear and concise description of what you expected to happen.\n\n**Logs**\n2025-11-17 12:22:01.801 [info] Error reading from async stream, we will reconnect: TypeError: terminated\n2025-11-17 12:27:03.682 [info] Error reading from async stream, we will reconnect: TypeError: terminated\n\n**Additional context**\nRestarting it did not work.

The `@modelcontextprotocol/server-filesystem` MCP server generates unbounded log files in `%APPDATA%\\Claude\\logs\\mcp-server-filesystem*.log` (Windows) / `~/Library/Logs/Claude/` (macOS) that can grow to excessive sizes (17+ MB observed), creating several issues:\n\n1. **Performance degradation**: Large log files slow down log viewing and parsing during troubleshooting\n2. **Disk space waste**: Logs consume unnecessary space without automatic cleanup\n3. **Troubleshooting obstruction**: Ironically, oversized logs defeat their debugging purpose by becoming unwieldy\n4. **User maintenance burden**: Manual cleanup required, which most users won't perform regularly\n\n**Describe the solution you'd like**\n\nAdd configurable log rotation with size-based and/or time-based triggers:\n\n### Proposed Configuration Options\n\n**Environment Variables:**\n```bash\nMCP_FILESYSTEM_LOG_MAX_SIZE=10485760 # Max log size in bytes (default: 10MB)\nMCP_FILESYSTEM_LOG_MAX_FILES=5 # Number of rotated logs to retain (default: 5)\nMCP_FILESYSTEM_LOG_ROTATION=size # Rotation strategy: 'size', 'time', or 'both' (default: size)\nMCP_FILESYSTEM_LOG_INTERVAL=86400 # Rotation interval in seconds (default: daily)\n```\n\n**Alternative: Command-line Arguments:**\n```bash\nnpx @modelcontextprotocol/server-filesystem \\\n --log-max-size 10M \\\n --log-max-files 5 \\\n --log-rotation size \\\n /path/to/allowed/dir\n```\n\n### Rotation Behavior\n\n1. **Size-based rotation**: When log file exceeds `LOG_MAX_SIZE`, rotate immediately\n2. **Time-based rotation**: Rotate at fixed intervals (e.g., daily at midnight)\n3. **File naming convention**: `mcp-server-filesystem.log`, `mcp-server-filesystem.log.1`, `mcp-server-filesystem.log.2`, etc.\n4. **Automatic cleanup**: Delete oldest log when `LOG_MAX_FILES` limit reached\n5. **Graceful degradation**: If rotation fails, log to stderr and continue operation\n\n**Describe alternatives you've considered**\n\n1. **External log rotation tools**: \n - Windows Task Scheduler + batch scripts\n - Linux `logrotate`\n - **Problem**: Requires per-user configuration; not portable across installations\n\n2. **Desktop Commander MCP**: Includes 10MB auto-rotation but introduces complexity for users only needing basic filesystem access\n\n3. **Manual periodic deletion**: Impractical; most users unaware logs exist until problems arise\n\n**Additional context**\n\n- Related discussion: Issue #1879 proposes environment variable configuration; log management would complement that effort\n- Community need: Multiple users report log bloat issues in Discord/support channels\n- Reference implementation: Desktop Commander MCP successfully implements 10MB rotation\n\n**Implementation Notes**\n\nConsider using established Node.js logging libraries with built-in rotation:\n- `winston` with `winston-daily-rotate-file`\n- `pino` with `pino-roll`\n- Or lightweight custom implementation (~50 LOC)\n\nDefault to conservative settings (10MB max, 5 file retention) to balance disk usage against debugging needs.\n\n**Would you be willing to submit a PR?**\n\nPotentially, depending on maintainer guidance regarding preferred implementation approach (library vs. custom, env vars vs. CLI args).", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2975/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2962", "id": 3598563615, "node_id": "I_kwDONRaG_87Wfbkf", "number": 2962, "title": "filesystem MCP server still doesn't support legal Windows pathnames in claude_desktop_config.json", "user": { "login": "NemanSyed", "id": 38197868, "node_id": "MDQ6VXNlcjM4MTk3ODY4", "avatar_url": "https://avatars.githubusercontent.com/u/38197868?v=4", "gravatar_id": "", "url": "https://api.github.com/users/NemanSyed", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-11-07T03:50:05Z", "updated_at": "2025-11-07T03:50:05Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "Please see the closed https://github.com/modelcontextprotocol/servers/issues/447 for the full story.

It fails to automatically proceed to the next thought or action, causing the entire task to stall.\n\n### **To Reproduce**\n\nSteps to reproduce the behavior:\n\n1. Start a task that requires multi-step reasoning using either `augment agent` or `claude code`.\n2. Ensure the `Sequential_Thinking` mode is triggered.\n3. Monitor the agent's execution flow until it makes an `mcp` call within its `THOUGHT` process.\n4. Observe that after the current `THOUGHT` is complete, the agent gets stuck in a loading state and does not advance to the next step.\n\n**Workaround:**\nThe user must manually stop the generation and then send a new message (e.g., \"continue\" or \"go on\") to prompt the agent to resume the task. However, the issue may recur in subsequent steps.\n\n### **Expected behavior**\n\nWithin a `Sequential_Thinking` flow, after completing a `THOUGHT` step that includes an `mcp` call, the agent should seamlessly and automatically proceed to the next `THOUGHT` until the task is complete, without requiring any manual intervention.\n\n### **Logs**\n\nWhile detailed text logs are not available, the attached screenshot illustrates the point of failure. As shown, the agent has completed the 7th thought (`THOUGHTNUMBER: 7`) and recognizes that a next step is required (`NEXTTHOUGHTNEEDED: true`), but it fails to automatically advance to the 8th thought.\n\n\"Image\"\n\n\"Image\"\n\n```\n// State similar to the one in the screenshot\nTHOUGHT\n...

Meaning, that this capability will be handled in the LLM side instead of the MCP side.\nFrom my experience, LLMs have hard time to calculate time on their own, so if I run the \"get_current_time\" tool, the LLM might not be able to deduce the new time from the returned string.

This is highly unusual given the input is a standard Python list of dictionaries.\n\n## Troubleshooting Attempts\n\nMultiple strategies were employed to diagnose and bypass the error, all of which were unsuccessful.\n\n### Attempt 1: Standard Dictionary Literal\n\n- **Action:** Passed a standard Python list of dictionaries as a keyword argument.\n- **Result:** Failed with the persistent JSON parsing error.\n\n### Attempt 2: Escaping Special Characters\n\n- **Action:** Escaped all single quotes within string values (`\\'` ) to prevent potential string termination issues.\n- **Result:** Failed with the same error.\n\n### Attempt 3: Separating Creation and Observation\n\n- **Action:** Called `create_entities` with only `name` and `entityType`, followed by a separate `add_observations` call.\n- **Result:** `create_entities` failed with a validation error (`'observations' is a required property`), proving this approach was incorrect. The `add_observations` call failed with the same JSON parsing error.\n\n### Attempt 4: Simplifying Input\n\n- **Action:** Removed all special characters, spaces, and punctuation from all string literals, using only alphanumeric characters and underscores.\n- **Result:** Failed with the same error, indicating the issue is not with the content of the strings themselves.\n\n### Attempt 5: Individual, Atomic Calls\n\n- **Action:** The final attempt involved breaking the request into individual tool calls for every single entity and relation, with each call containing a list with only one dictionary object.\n- **Result:** Every single call failed with the exact same JSON parsing error.\n\n## Conclusion\n\nThe error's consistency across vastly different inputs (from complex lists to single, simple objects) and its specific failure position (102) strongly suggest a systemic bug in the tool's argument parsing layer. It does not appear to be related to the user-provided input's content or structure, as all reasonable formats have been attempted. The tool appears to be fundamentally unable to parse the list of dictionaries passed to it.", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2689/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2680", "id": 3386164023, "node_id": "I_kwDONRaG_87J1MM3", "number": 2680, "title": "Toolsmith APP Comprehensive Testing Suite", "user": { "login": "omri10007", "id": 187197989, "node_id": "U_kgDOCyhqJQ", "avatar_url": "https://avatars.githubusercontent.com/u/187197989?v=4", "gravatar_id": "", "url": "https://api.github.com/users/omri10007", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": {}, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-09-05T03:46:33Z", "updated_at": "2025-09-05T03:46:33Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": null, "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2680/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2659", "id": 3371843657, "node_id": "I_kwDONRaG_87I-kBJ", "number": 2659, "title": "Request: Review auto-generated MCP permission manifest for Time", "user": { "login": "buehler", "id": 1067213, "node_id": "MDQ6VXNlcjEwNjcyMTM=", "avatar_url": "https://avatars.githubusercontent.com/u/1067213?v=4", "gravatar_id": "", "url": "https://api.github.com/users/buehler", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": {}, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-09-01T08:54:52Z", "updated_at": "2025-09-01T08:54:52Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "Dear Authors / Maintainers,\n\nWe are researchers from the University of St. Gallen studying how to make Model Context Protocol (MCP) servers safer to run via a sandboxed permission system.

The root cause was a combination of a race condition in the server's file-writing logic and an environment misconfiguration that prevented the execution of the corrected code. The issue was ultimately resolved after the user manually deleted the corrupted `memory.json` file, allowing the fixed server environment to take over.\n\n### Root Cause Analysis\n\nThe investigation revealed a multi-faceted root cause:\n\n1. **Code Bug:** The server's code lacked a file lock on the `memory.json` file. This created a **race condition** where concurrent writes would corrupt the file. This was demonstrated by the provided `test_race_condition.py` script.\n2. **Data Corruption:** The corrupted `memory.json` file was the direct cause of the JSON parsing errors. The server would attempt to read the malformed file and fail.\n3. **Environment Issue:** The primary blocker was an environment misconfiguration. The system was using `npx` to run an old, buggy version of the server from the internet, instead of the locally compiled and fixed version that included the race condition fix.\n\n### Evidence of the Bug (Race Condition)\n\nThe following Python script simulates the original buggy logic. It starts two processes that attempt to write to the same JSON file concurrently without a lock. This can result in a corrupted file, demonstrating the race condition.\n\n
\nBug Simulation Code\n\n```python\nimport json\nimport os\nfrom multiprocessing import Process, Manager\n\n# The file to be shared and potentially corrupted\nTEST_FILE = 'test_memory.json'\n\n# This function simulates the buggy load/save logic from the TypeScript code\ndef buggy_operation(process_id, new_entry, shared_dict):\n \"\"\"Simulates a single process reading, updating, and writing the file.\"\"\"\n try:\n # 1. Load the graph (read from file)\n try:\n with open(TEST_FILE, 'r') as f:\n data = f.read()\n # In a race condition, this data could be incomplete\n graph = json.loads(data) if data else {'entries': []}\n except (FileNotFoundError, json.JSONDecodeError):\n graph = {'entries': []}\n\n # 2. Add the new entry\n graph['entries'].append(new_entry)\n \n # 3. Save the graph (write back to file)\n with open(TEST_FILE, 'w') as f:\n # This is the critical section where the race condition happens.\n # One process can overwrite the other's changes.\n json.dump(graph, f)\n \n shared_dict[process_id] = 'Success'\n\n except Exception as e:\n # If a json.JSONDecodeError happens, it means we read a corrupted file\n shared_dict[process_id] = f'Error: {type(e).__name__} - {e}'\n\ndef main():\n \"\"\"Run two buggy operations in parallel to try and trigger the race condition.\"\"\"\n # Clean up previous test file if it exists\n if os.path.exists(TEST_FILE):\n os.remove(TEST_FILE)\n\n with Manager() as manager:\n shared_dict = manager.dict()\n \n # Create two processes that will run the buggy operation concurrently\n p1 = Process(target=buggy_operation, args=(1, {'id': 1, 'data': 'from_process_1'}, shared_dict))\n p2 = Process(target=buggy_operation, args=(2, {'id': 2, 'data': 'from_process_2'}, shared_dict))\n\n p1.start()\n p2.start()\n\n p1.join()\n p2.join()\n\n print(\"--- Process Results ---\")\n for pid, result in shared_dict.items():\n print(f\"Process {pid}: {result}\")\n\n print(\"\\n--- Final File Content ---\")\n try:\n with open(TEST_FILE, 'r') as f:\n content = f.read()\n print(content)\n # Final check: is the file valid JSON?\n final_data = json.loads(content)\n print(\"\\n--- Final Parsed Data ---\")\n print(final_data)\n if len(final_data.get('entries', [])) != 2:\n print(\"\\n*** BUG CONFIRMED: Data was lost. Expected 2 entries. ***\")\n else:\n print(\"\\n*** TEST PASSED (Race condition not triggered this time) ***\")\n\n except (FileNotFoundError, json.JSONDecodeError) as e:\n print(f\"*** BUG CONFIRMED: File is corrupted or does not exist. ***\")\n print(f\"Error: {e}\")\n finally:\n # Clean up the test file\n if os.path.exists(TEST_FILE):\n os.remove(TEST_FILE)\n\n\nif __name__ == '__main__':\n main()\n```\n\n
\n\n### The Fix (Locking Mechanism)\n\nThe corrected code uses a file-based lock to ensure that only one process can write to the `memory.json` file at a time, preventing the race condition. The following script demonstrates this fixed logic.\n\n
\nFix Verification Code\n\n```python\nimport os\nimport json\nfrom multiprocessing import Process, Manager, Lock\n\nclass FixedKnowledgeGraphManager:\n def __init__(self, memory_file_path, lock):\n self.memory_file_path = memory_file_path\n self.lock = lock\n\n def _load_graph_safe(self):\n \"\"\"Safely loads the graph from the JSON file.\"\"\"\n try:\n with open(self.memory_file_path, 'r') as f:\n data = f.read()\n return json.loads(data) if data else {'entities': [], 'relations': []}\n except FileNotFoundError:\n return {'entities': [], 'relations': []}\n\n def _save_graph_safe(self, graph):\n \"\"\"Safely saves the graph to the JSON file.\"\"\"\n with open(self.memory_file_path, 'w') as f:\n json.dump(graph, f, indent=2)\n\n def _execute_with_lock(self, operation, *args, **kwargs):\n \"\"\"Executes a given file operation with a lock.\"\"\"\n with self.lock:\n graph = self._load_graph_safe()\n result, updated_graph = operation(graph, *args, **kwargs)\n self._save_graph_safe(updated_graph)\n return result\n\n def create_entities(self, graph, entities):\n new_entities = [e for e in entities if e['name'] not in {ex['name'] for ex in graph['entities']}]\n graph['entities'].extend(new_entities)\n return new_entities, graph\n\n def create_relations(self, graph, relations):\n # Simple add for testing; a real implementation would check for duplicates\n graph['relations'].extend(relations)\n return relations, graph\n\n # Wrapper methods that will be called by the test processes\n def safe_create_entities(self, entities):\n return self._execute_with_lock(self.create_entities, entities)\n\n def safe_create_relations(self, relations):\n return self._execute_with_lock(self.create_relations, relations)\n\n\nTEST_FILE = 'test_memory_fixed.json'\n\ndef safe_operation(process_id, entities_to_add, relations_to_add, shared_dict, lock):\n \"\"\"Performs concurrent operations using the fixed manager.\"\"\"\n try:\n manager = FixedKnowledgeGraphManager(TEST_FILE, lock)\n manager.safe_create_entities(entities_to_add)\n manager.safe_create_relations(relations_to_add)\n shared_dict[process_id] = 'Success'\n except Exception as e:\n shared_dict[process_id] = f'Error: {type(e).__name__} - {e}'\n\ndef main():\n \"\"\"Run two safe operations in parallel to verify the fix.\"\"\"\n if os.path.exists(TEST_FILE):\n os.remove(TEST_FILE)\n\n with Manager() as process_manager:\n shared_dict = process_manager.dict()\n lock = Lock()\n\n # Define data for two processes\n data_p1 = {\n 'entities': [{'name': 'Human', 'entityType': 'Actor'}],\n 'relations': [{'from': 'Human', 'to': 'Start_Bank', 'relationType': 'is_at'}]\n }\n data_p2 = {\n 'entities': [{'name': 'Goat', 'entityType': 'Actor'}],\n 'relations': [{'from': 'Goat', 'to': 'Start_Bank', 'relationType': 'is_at'}]\n }\n\n p1 = Process(target=safe_operation, args=(1, data_p1['entities'], data_p1['relations'], shared_dict, lock))\n p2 = Process(target=safe_operation, args=(2, data_p2['entities'], data_p2['relations'], shared_dict, lock))\n\n p1.start()\n p2.start()\n\n p1.join()\n p2.join()\n\n print(\"--- Process Results ---\")\n for pid, result in shared_dict.items():\n print(f\"Process {pid}: {result}\")\n\n print(\"\\n--- Final File Content ---\")\n # We need a final read outside the lock to verify the final state\n try:\n with open(TEST_FILE, 'r') as f:\n final_graph = json.load(f)\n print(json.dumps(final_graph, indent=2))\n num_entities = len(final_graph.get('entities', []))\n num_relations = len(final_graph.get('relations', []))\n print(f\"\\nFound {num_entities} entities and {num_relations} relations.\")\n if num_entities == 2 and num_relations == 2:\n print(\"\\n*** BUG FIXED: All data was written successfully. ***\")\n else:\n print(f\"\\n*** TEST FAILED: Data was lost.

\n\n### Relation to Previously Reported Bugs\n\nThis issue is consistent with previously reported bugs in the `modelcontextprotocol/servers` repository, suggesting a systemic problem that has now been addressed:\n\n* **Direct Confirmation:** This bug is a direct parallel to **Issue #2412**, which reported the exact same \"Unexpected non-whitespace character\" error, although for the filesystem server. This confirms the problem was not isolated to a single server.\n* **Related Symptom:** The server timeouts and unexpected exits reported in **Issue #719** are also likely symptoms of the same underlying server instability caused by this bug.\n\n### Conclusion\n\nThe \"Unexpected non-whitespace character\" bug is **resolved**. The resolution required both a **code fix** (implementing a file lock to prevent the race condition) and an **environment fix** (ensuring the correct, locally-built server is executed).

This prevents using the server in environments where some paths may be intermittently available.\n\n## Current Behavior\n- Server performs `fs.stat()` on all configured paths during startup\n- If ANY path is unreachable, server terminates with `process.exit(1)`\n- This makes the entire filesystem server unusable when network paths are offline\n\n## Expected Behavior\nThe server should:\n1. **Start successfully** even if some network paths are temporarily unavailable\n2. **Log warnings** for unreachable paths instead of crashing\n3. **Gracefully handle operations** on unavailable paths at runtime with appropriate error messages\n4. **Optionally retry** path validation periodically or on-demand\n\n## Use Case\nMany users have configurations mixing local paths with network storage (NAS, SMB shares, etc.) that may not be available 24/7:\n- Home NAS systems that power down overnight\n- VPN-connected network drives\n- Intermittent cloud storage mounts\n\n## Reproduction\n```json\n{\n \"mcpServers\": {\n \"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"C:\\\\Users\\\\username\\\\Documents\",\n \"\\\\\\\\nas.local\\\\shared\\\\documents\" // <- NAS is offline\n ]\n }\n }\n}\n```\n\n**Current result:** Server fails to start completely\n**Expected result:** Server starts, local paths work, NAS operations fail gracefully\n\n## Proposed Solutions\n\n### Option 1: Command-line flag (recommended)\n```bash\nnpx @modelcontextprotocol/server-filesystem --ignore-missing-paths C:\\local \\\\nas\\share\n```\n\n### Option 2: Path-specific configuration\n```json\n{\n \"required\": [\"C:\\\\Users\\\\username\\\\Documents\"],\n \"optional\": [\"\\\\\\\\nas.local\\\\shared\\\\documents\"]\n}\n```\n\n### Option 3: Runtime validation only\nSkip startup validation entirely, handle path availability at operation time.\n\n## Impact\nThis enhancement would:\n- ✅ Improve reliability in mixed local/network environments\n- ✅ Reduce configuration management complexity\n- ✅ Allow for more flexible deployment scenarios\n- ✅ Maintain backward compatibility\n\n## Environment\n- OS: Windows 11\n- Package: @modelcontextprotocol/server-filesystem (latest)\n- Client: Claude Desktop\n\n## Related Issues\nSimilar issues suggest this is a common pain point:\n- #1838 (path validation issues on Windows)\n- #267 (server connection failures)\n- #75 (Windows filesystem configuration issues)\n\n## Additional Context\nThe current \"fail-fast\" approach makes sense for critical paths but is too rigid for optional network resources.

When using relative paths, it incorrectly throws an \"Access denied\" error even though the path is within allowed directories.\n\n## Steps to Reproduce\n1. Configure filesystem MCP with allowed directories (see config below)\n2. Try to create a directory using a relative path:\n ```javascript\n mcp_filesystem_create_directory({ path: \"./Dishank\" })\n ```\n3. Observe error: `Error: Access denied - path outside allowed directories: c:\\Learn\\import_tracker\\Dishank not in C:\\Learn\\import_tracker, C:\\Users\\ADMIN\\.kiro, C:\\Learn\\import_tracker`\n\n4. Try with absolute path:\n ```javascript\n mcp_filesystem_create_directory({ path: \"C:\\\\Learn\\\\import_tracker\\\\Dishank\" })\n ```\n5. This works successfully: `Successfully created directory C:\\Learn\\import_tracker\\Dishank`\n\n## Expected Behavior\nBoth relative and absolute paths should work as long as they resolve to a location within the allowed directories.\n\n## Current Configuration\n```json\n{\n \"mcpServers\": {\n \"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"C:\\\\Learn\\\\import_tracker\",\n \"C:\\\\Users\\\\ADMIN\\\\.kiro\",\n \".\"\n ],\n \"disabled\": false,\n \"autoApprove\": [\n \"read_file\"\n ]\n }\n }\n}\n```\n\n## Environment\n- **OS**: Windows\n- **Platform**: win32\n- **Shell**: cmd\n- **Kiro IDE**: Version: 0.1.25 (user setup)\n VSCode Version: 1.94.0\n Commit: 6124c448360adbeb0adbc771a86db283d2d3f4db\n Date: 2025-07-23T19:45:58.809Z\n Electron: 30.5.1\n ElectronBuildId: undefined\n Chromium: 124.0.6367.243\n Node.js: 20.16.0\n V8: 12.4.254.20-electron.0\n OS: Windows_NT x64 10.0.26100\n- **MCP Server Version**: @modelcontextprotocol/server-filesystem (latest via npx)\n- **Node.js**: 18+ (required for Kiro)\n\n## Additional Context\nThe error message shows that the server is correctly resolving the relative path to its absolute form (`c:\\Learn\\import_tracker\\Dishank`), but then fails to recognize that this path is within the allowed directories list, even though `C:\\Learn\\import_tracker` is explicitly listed as an allowed directory.\n\nThis appears to be a path normalization issue where the comparison between the resolved path and allowed directories is failing due to case sensitivity or path format differences.\n\n## Reproduction via Kiro IDE\nThis issue was discovered while using Kiro IDE's MCP integration. The filesystem MCP server was configured through Kiro's `.kiro/settings/mcp.json` configuration file, and the issue manifested when attempting to create directories through Kiro's AI assistant using the `mcp_filesystem_create_directory` tool.\n\n## Impact\nThis bug affects the usability of the filesystem MCP server when integrated with IDEs like Kiro, as users naturally expect relative paths to work within their project workspace.", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/2416/reactions", "total_count": 1, "+1": 1, "-1": 0,

indexing system that dynamically analyzes MCP memory content and generates optimized index entities for efficient token usage and faster information retrieval.\n\n## Problem Statement\nThe use of MCP Memory is the primary source of notes and list items for several projects and IDE's.\nCurrent MCP memory systems suffer from token inefficiency when retrieving information:\n- Large memory files (80k+ tokens) result in expensive queries\n- Manual index creation is time-consuming and error-prone\n- Generic search patterns don't leverage content structure\n- No automatic optimization for common access patterns\n\n## Proposed Solution\nImplement an indexing system that:\n\n### 1. **Content Analysis Engine**\n- Automatically scans all entities in memory.json\n- Identifies content patterns and categories (Directives, project status, file locations, etc.)\n- Extracts key information using pattern matching and keyword detection\n- Builds content category maps based on actual memory content\n\n### 2. **Dynamic Index Generation**\n- Creates summary entities only for content categories that exist\n- Generates optimized observations limited to essential information\n- Produces consistent naming conventions for quick access commands\n- Maintains backward compatibility with existing memory structure\n\n### 3. **Token Optimization**\n- Limits index entity size to <500 tokens each\n- Creates hierarchical access patterns (summary → detailed → comprehensive)\n- Implements content prioritization (most relevant information first)\n- Provides progressive detail strategies for complex queries\n\n### 4. **Command Integration**\n- Generates standardized quick access commands (memrules, memstatus, etc.)\n- Creates mapping between commands and specific index entities\n- Implements fallback strategies for missing content\n- Maintains consistent search patterns across projects\n\n## Technical Requirements\n\n### Core Components Needed:\n1. **Memory Parser**: Read and parse JSON Lines format memory files\n2. **Pattern Analyzer**: Detect content categories using configurable patterns\n3. **Index Generator**: Create optimized summary entities dynamically\n4. **Command Mapper**: Generate quick access command definitions\n5. **Output Writer**: Write optimized memory files with indexes\n\n### Configuration Support:\n- Configurable content patterns for different project types\n- Adjustable token limits per index category\n- Customizable command naming conventions\n- Optional index categories based on project needs\n\n### Performance Targets:\n- Generate indexes with <500 tokens each\n- Achieve 95%+ token reduction for common queries\n- Support memory files with 1000+ entities\n\n\n## Expected Benefits\n\n### For System Performance:\n- **Lower API costs** due to reduced token usage\n- **Faster response times** with targeted queries\n- **Improved scalability** as memory files grow\n- **Better user experience** with consistent performance\n\n\n## Compatibility Requirements\n- Maintain full backward compatibility with existing memory.json format\n- Support both JSON Lines and standard JSON input formats\n- Work with existing MCP server implementations\n- Preserve all existing entity relationships and metadata\n\n", "closed_by": null, "reactions": { "url":

"blocking": 0, "total_blocking": 0 }, "body": "**Describe the bug**\nWhen using either `search_nodes` or `open_nodes` tools from the memory graph MCP, an unintuitive behaviour arises regarding relation search. For a relation to be included in the results, it needs to relate entities present in the search query in *both* ends (`from` and `to`). Arguably, this makes relations very hard to be discovered by an agent and the graph nearly impossible to explore.\n\nI open this as a bug suspecting that this is not the intended behavior, but I apologize in advance if it is. If that's the case, instead I would suggest this as an enhancement.\n\n**To Reproduce**\nSteps to reproduce the behavior:\n1. Create the knowledge graph described later.\n2. Ask an agent to use the open_nodes tool directly to open the `Zero Cool` node.\n\nKnowledge graph:\n```\n{\"type\":\"entity\",\"entityType\":\"person\",\"name\":\"Zero Cool\"}\n{\"type\":\"entity\",\"entityType\":\"Person\",\"name\":\"Dade Murphy\"}\n{\"type\":\"relation\",\"from\":\"Zero Cool\",\"relationType\":\"is\",\"to\":\"Dade Murphy\"}\n{\"type\":\"relation\",\"from\":\"Dade Murphy\",\"relationType\":\"is\",\"to\":\"Zero Cool\"}\n```\n\n**Expected behavior**\nWhat I expected was to obtain both the Zero Cool entity and all it's relations so it'd be possible for the agent to traverse the graph and research the existing information. Instead the response is the following:\n\n```\n{\n \"text\": \"{\\n \\\"entities\\\": [\\n {\\n \\\"type\\\": \\\"entity\\\",\\n \\\"entityType\\\": \\\"person\\\",\\n \\\"name\\\": \\\"Zero Cool\\\"\\n }\\n ],\\n \\\"relations\\\": []\\n}\",\n \"type\": \"text\"\n}\n```\n\nNotice the empty relations array. Instead, it should include all of \"Zero Cools\" relations.\n\nThe cause for this seems to be the following lines:\nhttps://github.com/modelcontextprotocol/servers/blob/220987921bc72409d35d1a5775597782ae688556/src/memory/index.ts#L172C1-L175C7\n\nThese are present in both `open_nodes` and `search_nodes` functions and require that **both** `to` and `from` sides be present in the search entity results to include a relation. This could potentially be resolved by changing the condition to include relations where either endpoint is present in the search result (i.e., using an `||` instead of `&&`).\n\nAlthough the current behavior might be advantageous in queries involving many entities, for a single entity query, it makes relations completely inaccesible. For agents exploring the knowledge graph starting from a single node, this restriction hides all useful relational context, breaking graph traversal. This diminishes the usefulness of both tools.\n\nFurthermore, if this is indeed the intended behavior then it might make sense to make an exception when there's only a single entity in the results.\n\nHappy to clarify or send a PR if this seems like a desirable fix.

This is not a bug report, but rather a feature suggestion and a contribution.\n\nI've been working with the `server-memory` component and noticed that the `memory.json` file is stored in a well-hidden location (e.g., `~/.nvm/versions/node/v20.19.3/lib/node_modules/@modelcontextprotocol/server-memory/dist/`). I have read the manual and understand that this location is configurable, which is helpful.\n\nTo make interacting with this data easier, I have developed a script that visualizes the contents of these JSON stream files as a PlantUML graph.

And in the worst case scenarios, might even contain sensitive information.\n\nPersonally, I'd go further and say allowing `filesystem` to work against any dot-prefixed filesystem objects is a _security_ risk, however, for the sake of wanting to keep this discussion focused on reducing token count rather than whether users should or should not be aware of what data they're sharing with the agent, this GH Issue is focused on dot-prefixed directories like `.git`.\n\n**To Reproduce**\nRun the MCP with the authorised path being the root of any project that is also a git repository.\n\n**Expected behavior**\nDot-prefixed directories should be ignored _by default_. An environmental variable and/or command line flag can be used to optionally re-enable this behaviour.\n\n**Logs**\n\n\n**Additional context**\nWhile the intended behaviour is to selectively include the files and/or directories you wish to authorise for use with this MCP, the benefit of using an MCP like this is for speed and convenience.

This makes the protocol fragile and unsuitable for production use.\n\n## Current Behavior\n\nWhen any path is inaccessible:\n- Entire filesystem server shuts down\n- ALL file access is lost (not just the invalid path)\n- No error recovery possible through Claude\n- Must restart Claude Desktop to restore functionality\n\n## Expected Behavior\n\n- Invalid paths should be skipped with a warning\n- Valid paths should continue working\n- Server should log errors but not crash\n- Graceful degradation, not total failure\n\n## Steps to Reproduce\n\n1. Configure MCP filesystem with a network mount:\n```json\n\"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"/Users/username/Desktop\",\n \"/Volumes/NetworkDrive\" // This is a Samba mount\n ]\n}\n```\n\n2. Start Claude Desktop - filesystem works normally\n3. Disconnect network/unmount the Samba share\n4. Filesystem server crashes completely\n5. Cannot access even `/Users/username/Desktop` anymore\n\n## Impact\n\n- **Severity**: Critical\n- **Frequency**: Happens whenever network conditions change\n- **Workaround**: None - must restart Claude Desktop\n\n## Real-World Example\n\nWorking on a project with files on both local disk and a Samba mount. Network hiccup occurs:\n- Samba mount at `/Volumes/Code` becomes unavailable\n- MCP filesystem server completely dies\n- Cannot read local logs to debug\n- Cannot edit local config files to remove the bad path\n- Cannot continue any file-based work until full restart\n\n## Proposed Solution\n\n```javascript\n// pseudocode\nasync function initializePaths(configuredPaths) {\n const validPaths = [];\n \n for (const path of configuredPaths) {\n try {\n await fs.access(path);\n validPaths.push(path);\n console.log(`✓ Registered path: ${path}`);\n } catch (error) {\n console.warn(`✗ Skipping inaccessible path: ${path} - ${error.message}`);\n // Continue with other paths instead of crashing\n }\n }\n \n if (validPaths.length === 0) {\n throw new Error(\"No valid paths found\");\n }\n \n return validPaths;\n}\n```\n\n## Additional Context\n\nThis \"all-or-nothing\" approach contradicts basic fault tolerance principles. For MCP to be a production-ready standard for LLM tool integration, it must handle common scenarios like:\n- Network drives going offline\n- Typos in configuration\n- Permissions changes\n- Mounted volumes being unmounted\n\nThe current behavior makes MCP fragile and frustrating to use in real development environments.\n\n## Environment\n\n- OS: macOS [your version]\n- Claude Desktop: [your version]\n- MCP filesystem server version: [check package.json]\n\n## Related Issues\n\n- [Check if there are similar issues and reference them]\n\n---\n\n**Note**: This issue affects anyone using MCP with network storage, external drives, or complex file system configurations.

This affects file organization workflows and creates inconsistent behavior between file listing and file manipulation operations.\n\n## **Environment**\n- **OS**: macOS (multiple versions affected) \n- **MCP Server**: @modelcontextprotocol/server-filesystem\n- **Node.js**: (applicable versions)\n- **Files Affected**: System-generated screenshot files specifically\n\n## **Bug Description**\n\n### **Expected Behavior**\n- Files visible in `list_directory` operations should be accessible for `move_file`, `read_file`, and other filesystem operations\n- All files with standard characters (including spaces) should be movable\n\n### **Actual Behavior**\n- Screenshot files appear in directory listings but throw `ENOENT: no such file or directory` errors during move/access operations\n- Regular files with spaces work perfectly when created manually\n- Only affects macOS system-generated screenshots\n\n## **Reproduction Steps**\n\n1. Take screenshots on macOS (creates files like `Screenshot 2025-04-23 at 2.40.40 PM.png`)\n2. Use MCP `list_directory` tool - files appear normally\n3. Attempt to use `move_file` or `read_file` on these screenshots\n4. Operations fail with ENOENT errors\n5. Create a test file with similar naming manually - it works fine\n\n## **Root Cause Analysis**\n\nmacOS screenshot files contain **non-standard Unicode characters**:\n- Non-breaking spaces (U+00A0) instead of regular spaces (U+0020) \n- Special Unicode characters in timestamps and punctuation\n- Extended file attributes that interfere with standard Node.js file operations\n\n### **Evidence**\n```bash\n# This works (manually created file)\ntouch \"Screenshot 2025-04-23 at 2.40.40 PM copy.png\"\n# MCP can move this file successfully\n\n# This fails (macOS system-generated) \nmv \"Screenshot 2025-04-23 at 2.40.40 PM.png\" ./Images/\n# ENOENT error in MCP operations\n```\n\n## **Impact**\n- **High**: Affects common file organization workflows\n- **User Experience**: Creates confusion when \"visible\" files can't be accessed\n- **Productivity**: Forces manual workarounds for basic file management\n- **Cross-platform**: Specifically impacts macOS users with no clear error messaging\n\n## **Workarounds Currently Available**\n\n### **For Users:**\n1. Manual drag-and-drop in Finder\n2. Rename files to simpler names first\n3. Use Terminal with shell globbing: `mv Screenshot*.png ./Images/`\n\n### **For Developers:**\n```javascript\n// Unicode normalization before file operations\nfunction normalizeFilename(filename) {\n return filename\n .normalize('NFC')\n .replace(/\\u00A0/g, ' ') // Replace non-breaking spaces\n .replace(/[\\u2000-\\u206F]/g, ' '); // Replace Unicode spaces\n}\n```\n\n## **Proposed Solutions**\n\n### **1. Unicode Normalization (Recommended)**\n- Implement filename normalization before all file operations\n- Handle common Unicode edge cases in filesystem operations\n- Add this to the core MCP filesystem server\n\n### **2. Better Error Handling**\n- Distinguish between \"file not found\" vs \"file access encoding issues\"\n- Provide more descriptive error messages for Unicode-related failures\n- Suggest normalization when Unicode issues are detected\n\n### **3. Alternative Access Methods**\n- Use native OS APIs that handle Unicode edge cases better\n- Implement fallback mechanisms for problematic filenames\n\n### **4. Documentation & Warning**\n- Document known limitations with macOS screenshot files\n- Provide clear workarounds in the README\n- Add warning in error messages about potential Unicode issues\n\n## **Technical Implementation Suggestion**\n\n```typescript\n// Add to filesystem operations\nfunction sanitizeFilePath(filePath: string): string {\n return filePath\n .normalize('NFC')\n .replace(/\\u00A0/g, ' ')\n .replace(/[\\u2000-\\u206F\\u2E00-\\u2E7F]/g, ' ');\n}\n\n// Apply before all file operations\nexport async function moveFile(source: string, destination: string) {\n const normalizedSource = sanitizeFilePath(source);\n const normalizedDest = sanitizeFilePath(destination);\n // ... existing move logic\n}\n```\n\n## **Testing Files**\nI can provide test screenshot files demonstrating this issue if needed for reproduction.\n\n## **Related Issues**\nThis may affect other MCP filesystem implementations:\n- mark3labs/mcp-filesystem-server \n- bsmi021/mcp-filesystem-server\n- Other Node.js based filesystem MCPs\n\n---\n\n**Request**: This impacts daily productivity for macOS users. Unicode normalization would solve this elegantly while maintaining backward compatibility.\n\nLet me know if you need additional details, test files, or are interested in a PR implementing the Unicode normalization solution.", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1970/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1939", "id": 3096350327, "node_id": "I_kwDONRaG_864jo53", "number": 1939, "title": "\"error\":{\"code\":-32601,\"message\":\"Method not found\"}}", "user": { "login": "mimosel", "id": 129038745, "node_id": "U_kgDOB7D5mQ", "avatar_url": "https://avatars.githubusercontent.com/u/129038745?v=4", "gravatar_id": "", "url": "https://api.github.com/users/mimosel", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-05-28T07:30:25Z", "updated_at": "2025-05-28T07:30:52Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Describe the bug**\nWhen asking Claude Desktop to implement changes to my code, it stops working and says \"Claude will return soon\nClaude.ai is currently experiencing a temporary service disruption.

This approach can become unwieldy and hard to manage when complex configurations are needed. I propose adding support for environment variable-based configuration to improve usability.\n\n## Proposed Changes\n\nAllow configuration of allowed and denied directories through the following environment variables:\n\n- `ALLOWED_DIRS`: Semicolon-separated list of allowed directories\n- `ALLOWED_READONLY_DIRS`: Semicolon-separated list of read-only allowed directories\n- `DENIED_DIRS`: Semicolon-separated list of denied directories\n- `RECURSIVE`: When set to \"true\", all subdirectories of allowed directories are also allowed\n\nExisting command-line argument functionality would be maintained for backward compatibility.\n\n## Benefits\n\n1. **Improved Readability**: Complex directory configurations can be expressed more cleanly\n2. **Easier Management**: Multiple directories can be configured in a single line with semicolon separators\n3. **Reusability**: Environment variables can be easily reused in scripts or Docker configurations\n4. **Backward Compatibility**: Existing command-line argument approach continues to work\n\n## Implementation Example\n\nHere's an example of changes to the index.ts file:\n\n```typescript\n// Load settings from environment variables\nfunction parseDirectories(envVarValue: string | undefined): string[] {\n if (!envVarValue) return [];\n return envVarValue\n .split(';')\n .map((dir) => dir.trim())\n .filter(Boolean);\n}\n\n// Get settings from environment variables\nconst envAllowedDirs = parseDirectories(process.env.ALLOWED_DIRS);\nconst envAllowedReadOnlyDirs = parseDirectories(process.env.ALLOWED_READONLY_DIRS);\nconst envDeniedDirs = parseDirectories(process.env.DENIED_DIRS);\nconst envRecursive = process.env.RECURSIVE === 'true';\n\n// Parse command-line arguments\nconst args = process.argv.slice(2);\nif (args.length === 0 && envAllowedDirs.length === 0 && envAllowedReadOnlyDirs.length === 0) {\n console.error(\n 'Usage: mcp-server-filesystem [options] [additional_directories...]'\n );\n // ... existing help text ...\n console.error('');\n console.error('Configuration via environment variables:');\n console.error(' ALLOWED_DIRS: Semicolon-separated list of allowed directories');\n console.error(\n ' ALLOWED_READONLY_DIRS: Semicolon-separated list of read-only allowed directories'\n );\n console.error(' DENIED_DIRS: Semicolon-separated list of denied directories');\n console.error(\n ' RECURSIVE: When set to \"true\", all subdirectories of allowed directories are also allowed'\n );\n console.error(' Example:');\n console.error(\n ' ALLOWED_DIRS=\"/home/user;/home/user/projects\" DENIED_DIRS=\"/home/user/.ssh;/home/user/.config\" RECURSIVE=\"true\" mcp-server-filesystem'\n );\n process.exit(1);\n}\n```\n\n## Usage Example\n\nExample in mcp.json file:\n\n```json\n{\n \"mcpServers\": {\n \"filesystem\": {\n \"command\": \"node\",\n \"args\": [\"/path/to/filesystem/dist/index.js\"],\n \"env\": {\n \"ALLOWED_DIRS\": \"/home/user\",\n \"ALLOWED_READONLY_DIRS\": \"/home/user/Documents;/home/user/Library/Mobile Documents/com~apple~CloudDocs\",\n \"DENIED_DIRS\": \"/home/user/.ssh;/home/user/.config;/home/user/.local;/home/user/.cache;/home/user/.npm;/home/user/.yarn;/home/user/.pnpm;/home/user/.cargo;/Volumes/BackUp\",\n \"RECURSIVE\": \"true\"\n }\n }\n }\n}\n```\n\nI believe this enhancement will significantly improve the usability of the MCP Filesystem Server.\n", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1879/reactions", "total_count": 3, "+1": 3, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1869", "id": 3080556710, "node_id": "I_kwDONRaG_863nZCm", "number": 1869, "title": "Filesystem MCP server modified .env without permission and did not back it up", "user": { "login": "milisp", "id": 106554029, "node_id": "U_kgDOBlnirQ", "avatar_url": "https://avatars.githubusercontent.com/u/106554029?v=4", "gravatar_id": "", "url": "https://api.github.com/users/milisp", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" }, "1": { "id": 8351171797, "node_id": "LA_kwDONRaG_88AAAAB8cTE1Q", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/server-filesystem", "name": "server-filesystem", "color": "D4C5F9", "default": false, "description": "Reference implementation for the Filesystem MCP server -

It tried to “fix” a Tortoise ORM connection string issue by overwriting my file using the write_file command. However, it didn’t even read the .env file before modifying it, nor did it back it up. This led to loss of important config data I hadn’t committed.\n\n\n**To Reproduce**\nSteps to reproduce the behavior:\n1. Ask Claude (with the MCP server using filesystem) a question involving Docker and a Tortoise ORM connection string error.\n \n2. Claude tries to “fix” it automatically using write_file, modifying .env directly.\n \n3. File is overwritten without confirmation or backup.\n\n**Expected behavior**\nClaude or the MCP server should:\n\n- Never modify important user files like .env without explicit confirmation.\n \n- At minimum, back up the original file before overwriting.\n\n**Logs**\nError I originally asked about:\n\n```\n/Users/gpt/projects/rustapp/mcp-linker-api/docker-compose.yml \nConnectionRefusedError: [Errno 111] Connection refused\n```\n\nClaude’s attempted “fix”:\n\n```\n# Creates a .env file with a guessed Tortoise ORM connection string\n```\n\n**Additional context**\nThis issue could lead to silent data loss in projects where .env is not committed. Claude needs user confirmation step before file operations via MCP servers like filesystem.\n", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1869/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1868", "id": 3080284489, "node_id": "I_kwDONRaG_863mWlJ", "number": 1868, "title": "mcp-server-git: when performing git-add, it seems that git config is ignored", "user": { "login": "AlbertoGiraldo", "id": 24738419, "node_id": "MDQ6VXNlcjI0NzM4NDE5", "avatar_url": "https://avatars.githubusercontent.com/u/24738419?v=4", "gravatar_id": "", "url": "https://api.github.com/users/AlbertoGiraldo", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-05-21T13:40:07Z", "updated_at": "2025-05-21T13:42:45Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Desciption**\nWhen performing the `git add` command from terminal line, the changes are correctly identified and added for future commit. If a single line is added to a file, only that line is recognised as a change and added for later commit. \nHowever if the git-add is performed via the mcp-server-git, all the line endings are modified (in particular, a special character ^M is added at the end of each line of the added files). My guess is that Mcp-server-git is not taking into account the git config in my machine (in particular, the config that avoids bad behaviours with line endings, `git config --global core.autocrlf true`).\n\n**To Reproduce**\nSteps to reproduce the behavior:\n1. I am using Windows 11 Enterprise (version 24H2). In order to test the MCP server, I installed it with Python (pip install mcp-server-git) and I use it from the GitHub Copilot plugin inside IntelliJ (version of the plugin 1.5.44.10400-243). All this stack just to simplify my activities, it should not affect the result with the MCP server itself.\n2. I made a change (edited one line) in the codebase then asked Copilot to perform a git-add, the proposed command is a simple git add with the following parameters:\n`{\n \"files\": [\n \"src/main/resources/application.properties\"\n ],\n \"repo_path\": \"c:\\\\my_project\"\n}`\nHowever, when checking with an external tool what has been done (SourceTree, in my case) I see that all the lines have actually changed. Looking further, I see that all the lines now end with \"^M\" character\n\n3. Unstaging the file then doing the same `git add src/main/resources/application.properties` from the terminal, only my edited line is recognised as changed and staged for commit, as it should be\n\n**Expected behavior**\nThe mcp-server-git/mcp-server-git_git_add command should perform exactly the same as the git add command in the terminal. In particular, I expect the MCP server command to use my git config\n\n**Logs**\nI don't have useful logs and actually I'm not able to collect them.

Every time settings are synchronized, the path configured for one platform overwrites the other, causing the MCP filesystem server to stop working on the other platform.\n\n## Background\nIn the current implementation, filesystem paths are directly configured in the VS Code settings.json file like this:\n\n```json\n\"mcp\": {\n \"servers\": {\n \"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"${input:file_system_path}\" // Or hardcoded path like \"C:/Projects\"\n ]\n }\n },\n \"inputs\": [\n {\n \"id\": \"file_system_path\",\n \"type\": \"promptString\",\n \"description\": \"File System Path\"\n }\n ]\n}\n```\n\nThe issue occurs because Windows paths (e.g., \"C:\\\\Projects\") and macOS paths (e.g., \"/Users/username/Projects\") are incompatible, and when settings sync happens, one overwrites the other.\n\n## Proposed Solution\nImplement a platform-specific configuration option for filesystem paths in the MCP Server Filesystem. Some options:\n\n1. **Platform-specific inputs**: Allow different input variables for different platforms:\n```json\n\"mcp\": {\n \"inputs\": [\n {\n \"id\": \"file_system_path_windows\",\n \"type\": \"promptString\",\n \"description\": \"File System Path (Windows)\"\n },\n {\n \"id\": \"file_system_path_macos\",\n \"type\": \"promptString\", \n \"description\": \"File System Path (macOS)\"\n }\n ],\n \"servers\": {\n \"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"${os:windows?input:file_system_path_windows:input:file_system_path_macos}\"\n ]\n }\n }\n}\n```\n\n2. **Automatic platform detection**: Modify the filesystem server to automatically handle platform-specific paths:\n```javascript\n// In server code\nconst platformPath = os.platform() === 'win32' \n ? process.env.WINDOWS_PATH \n : process.env.MACOS_PATH;\n```\n\n3. **VS Code conditional settings**: Support a conditional syntax or settings overrides based on platform.\n\n## Benefits\n- Users can maintain a single synchronized settings.json that works on all platforms\n- No more broken MCP filesystem server on platform switching\n- Smoother cross-platform development experience\n\n## Affected Components\n- MCP Server Filesystem\n- VS Code settings handling\n\nWould appreciate if this could be considered for an upcoming release.

For example, in attempting to move such a file to a different directory, Claude reports back: \"encountered file access issues that prevented the direct move operation.\"\n\nRenaming the file (e.g. to replace the \"NARROW NO-BREAK SPACE\" character with a regular space character resolves the issue.\n\n**To Reproduce**\n\nMy Mac is running Sonoma OS 14.6.1 (23G93).\n\nMy claude_desktop_config.json file looks like this:\n\n{\n \"mcpServers\": {\n \"filesystem\": {\n \"command\": \"npx\",\n \"args\": [\n \"-y\",\n \"@modelcontextprotocol/server-filesystem\",\n \"/Users/bserridge/Screenshots\"\n ]\n }\n }\n}\n\nSteps to reproduce the behavior:\n1. Take a screenshot on the Mac; that'll generate a file with a name something like:\n\nScreenshot 2025-04-26 at 9.52.38 AM.png\n\nThe filename has several spaces in it, but the last space, right before the \"AM\", is not the usual \"SPACE\" character; rather, by default on the Mac when taking a screensho, it's the \"NARROW NO-BREAK SPACE\" character (U+202F)\n\n2. Ask Claude to move the file to a subdirectory. For example, the following two prompts reproduce the error:\n\nCan you make a new subdirectory (within Screenshots) called \"new\"?\n\nfollowed by:\n\nCould you please move the newest screenshot into the \"new\" subdirectory?\n\n**Expected behavior**\nA clear and concise description of what you expected to happen.\n\nI would expect the screenshot that I just took to be moved into the \"new\" subdirectory.\n\nInstead, Claude tries several times, using several different approaches, before giving up and concluding:\n\n\"I identified \"Screenshot 2025-01-18 at 11.15.43 AM.png\" as the newest file based on its filename.

Please describe.**\n\nCurrently, the `McpServer` implementation in the ModelContextProtocol likely handles client connections in a one-to-one manner. This means that only a single client can be actively communicating with the server at any given time. This limitation can be problematic in scenarios where multiple entities need to interact with the ModelContextProtocol server concurrently. For instance, in applications with multiple users or independent processes that need to access the server's functionalities, the current single-connection model would lead to queuing, delays, and a poor user experience.\n\n```mermaid\ngraph LR\n McpServer -- 1:1 --> Server\n Server -- 1:1 --> Transport\n Transport -- 1:1 --> Client\n```\n\n**Describe the solution you'd like**\n\nI propose enhancing the `McpServer` in the ModelContextProtocol typescript server implementations to support multiple concurrent client connections.\n\n\nThe sample code in Readme shows a way to maintain transports for clients in the express app layer, but since the spec has the concept of session, it is better managed inside the server SDK, i.e McpServer or `Server` maintains a `` mapping.

The same JSON configuration and command work fine in VSCode. This indicates the plugin server process may be exiting immediately after starting.\n\n**To Reproduce** \nSteps to reproduce the behavior: \n1. Enable the `sequential-thinking` plugin in Cursor \n2. Cursor attempts to run the command: \n ```bash\n cmd /c npx -y @modelcontextprotocol/server-sequential-thinking\n ``` \n3. The plugin briefly shows \"Enabled\" and then fails with `Client closed`\n\n**Expected behavior** \nThe plugin should start a persistent MCP server that Cursor can connect to and interact with, just like other MCP plugins such as `browser-tool-mcp`.\n\n**Logs** \nCursor log message: \n```\nClient closed\n``` \nManually running the command in a terminal does not produce errors and the server starts as expected.\n\n**Additional context** \nThis issue only happens with the `sequential-thinking` plugin. Other MCP plugins (e.g., `browser-tool-mcp`) work correctly in Cursor using the same setup and command structure. \nIt’s possible the server script does not block the main thread (e.g., missing `await app.listen()` or `server.listen()`), causing the process to exit immediately in non-interactive environments like Cursor. \n\n**Environment** \n- Cursor version: 0.47.8 (user setup) \n- VSCode version: 1.96.2 \n- Node.js: 20.18.1 \n- OS: Windows 11 (Windows_NT x64 10.0.26100)\n\n---\n", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1163/reactions", "total_count": 3, "+1": 3, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/1160", "id": 2960002347, "node_id": "I_kwDONRaG_86wbg0r", "number": 1160, "title": "Support read-only paths in filesystem MCP with npx", "user": { "login": "RonanKMcGovern", "id": 78278410, "node_id": "MDQ6VXNlcjc4Mjc4NDEw", "avatar_url": "https://avatars.githubusercontent.com/u/78278410?v=4", "gravatar_id": "", "url": "https://api.github.com/users/RonanKMcGovern", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432740, "node_id": "LA_kwDONRaG_88AAAABzvmeJA", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/enhancement", "name": "enhancement", "color": "a2eeef", "default": true, "description": "New feature or request" }, "1": { "id": 8351171797, "node_id": "LA_kwDONRaG_88AAAAB8cTE1Q", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/server-filesystem", "name": "server-filesystem", "color": "D4C5F9", "default": false, "description": "Reference implementation for the Filesystem MCP server - src/filesystem" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-03-31T09:45:50Z", "updated_at": "2025-04-26T14:48:13Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Is your feature request related to a problem?

Runs tests on both Ubuntu and Windows using GitHub's hosted runners\n2. Uses a matrix strategy to test both TypeScript and Python packages\n3. Runs in parallel with existing build workflows\n4.

This blueprint would be completely free, open-source, and require minimal involvement from the project maintainers.\n\n## What We're Offering\n\n[wirtual.dev](https://wirtual.dev) is creating standardized deployment blueprints for leading open-source AI applications. We'd like to create one for MCP servers that would:\n\n- Package MCP servers as a standardized blueprint for one-click enterprise deployment\n- Add enterprise-grade security controls and governance\n- Integrate with a shared context layer for interoperability between multiple MCP servers\n- Provide a secure environment for customization and extension\n\n## Value to MCP Ecosystem\n\nThis blueprint would:\n\n1. **Increase enterprise adoption** by removing deployment complexity barriers\n2. **Enhance security posture** with enterprise-grade controls around sensitive credentials and API access\n3. **Simplify configuration management** across multiple MCP servers in enterprise environments\n4. **Maintain full compatibility** with existing MCP clients like Claude Desktop\n5. **Preserve extensibility** while making it easier for enterprises to manage server deployment\n\n## What We Need From You\n\n- Permission to create this open-source blueprint for MCP servers\n- Optional: Any guidance on deployment best practices not already in documentation\n- Optional: Review of the blueprint when complete (though not required)\n\n## Important Assurances\n\n- The blueprint will be completely **open-source** under the same MIT license\n- There is **no vendor lock-in** - users can deploy without our platform if desired\n- The project **remains independent** - this is simply an additional deployment option\n- No changes to core codebases are needed\n\n## Project Alignment and Contribution Process\n\nWe're reaching out before beginning work to ensure our blueprint aligns with your project's vision and contribution standards. This approach helps us:\n\n1. Confirm the blueprint would be welcomed by the project maintainers\n2. Understand any specific requirements or preferences you might have\n3. Establish clear expectations about the review and merging process\n4. Ensure we're not duplicating efforts already underway\n\n## Next Steps\n\nIf you're open to this collaboration, we'd appreciate:\n\n1. Confirmation that this type of contribution would be welcomed\n2. Any specific guidance on how you'd prefer we reference this blueprint in your documentation\n3.

It suggests it might search file contents (like grep) when it actually only searches file and directory names. Claude itself is misinterpreting the function to search content in files, rather than file names matching input patterns.\n\n*Why it's confusing*\nThe function description starts with \"Recursively search for files and directories matching a pattern.\" This phrasing is ambiguous - it could mean either:\n1. Search for files/directories whose names match a pattern (actual behavior)\n2. Search recursively through directories for files containing content that matches a pattern (grep-like behavior many users expect)\n\nThis ambiguity leads to confusion when users (and Claude) attempt to use the function to search file contents and receive \"No matches found\" despite knowing the content exists in the files.\n\n**To Reproduce**\n1. Install Claude desktop for Mac Version 0.8.1\n2. Install and configure the `filesystem` server. Cleanup npm cache just to be sure the latest version is installed.\n3. Ask Claude desktop to search for content in files. Or ask Claude to refactor code, which typically leads Claude to try to \"grep\" content recursively in a directory.\n4. Notice Claude uses the `search_files` function to find content inside the files. Notice no matching content is found.\n\n```json\n{\n \"path\": \"/Users/my_userid/my_project_path/\",\n \"pattern\": \"mysearch\"\n}\nNo matches found\n```\n\n**Expected behavior**\nClaude should not use the `search_files` function to search for content.\n\n**Additional context**\nBoth Claude and human users may misinterpret this function as a content search tool (like grep) rather than a file/directory name matcher. The suggested description makes the distinction clear from the beginning and explicitly notes that it doesn't search file contents.\n\n**Suggested functions**\n\n1. search_files_by_name:\n \"Find files and directories whose names match a pattern. Searches recursively \n through all subdirectories from the starting path. The search is case-insensitive \n and matches partial file or directory names. Returns full paths to all items with \n matching names. Great for finding files when you don't know their exact location. \n Only searches within allowed directories.\"\n\n2. search_file_contents:\n \"Search for text patterns within file contents. Recursively examines all files \n under the specified directory and returns paths to files containing the search \n pattern. Functions similar to 'grep' command. The search can be case-sensitive \n or insensitive based on parameters. Returns matching file paths along with line \n numbers and context.

elements from processing, based on their id or class attributes. This functionality would grant users finer control over the content fetched, particularly in scenarios where specific sections of a webpage are irrelevant or detrimental to the intended data extraction.\n\n**Problem Statement:**\nCurrently, when fetching content from webpages with extensive sidebars or navigation menus—such as a lengthy index on the left side—the server retrieves these sections in large chunks (e.g., 20,000 tokens at a time). This can lead to inefficiencies, as large language models (LLMs) may process these sizable, non-essential sections first and prematurely determine that the website is unsuitable for the query, thereby diverting to alternative approaches. This behavior hampers the effectiveness of data retrieval and processing, especially when the main content is overshadowed by voluminous ancillary sections.\n\n**Use Case:**\nConsider a webpage where the left sidebar contains an extensive index with numerous items, each enclosed within
elements with specific ids or class names. A user interested solely in the main content would benefit from the ability to exclude these sidebar
elements during the fetching process, ensuring that the LLM focuses on the pertinent information without being sidetracked by the irrelevant index items.\n\n**Proposed Solution:**\nIntroduce a configuration option within the Fetch MCP Server that enables users to specify a list of ids and/or class names corresponding to
elements they wish to exclude from processing. The server would then bypass these elements during the fetching phase. This could be implemented through:\n\t1.\t**Configuration File**: Allow users to define the ids and class names to exclude within the server’s configuration file.\n\t2.\t**API Parameters**: Introduce API parameters that accept arrays of ids and class names to exclude during a fetch request.\n\n**Benefits:**\n\t•\t**Enhanced Data Relevance**: By excluding non-essential
elements, the fetched content becomes more focused on the main subject matter, improving the quality of data processed by LLMs. \n\t•\t**Optimized Token Utilization:** Reducing the amount of irrelevant content helps in staying within token limits of LLMs, thereby preventing premature termination of processing due to token overflows. \n\t•\t**Improved Processing Efficiency:** With less extraneous data to handle, the overall efficiency of data processing workflows is enhanced, leading to faster and more accurate outcomes.\n\n**Potential Challenges:**\n\t•\t**Complexity in Implementation:** Accurately identifying and excluding specified
elements without disrupting the overall structure of the fetched content may require sophisticated parsing mechanisms.\n\t•\t**User Configuration Errors:** Incorrectly specified ids or class names could lead to unintended exclusions, necessitating robust validation and clear documentation to guide users in configuring exclusions appropriately.\n\n**References:**\nThe need to manage large content sections during data processing with LLMs has been discussed in various forums. For instance, strategies to handle large HTML documents for LLMs with limited token sizes have been explored, highlighting the importance of content segmentation to optimize processing efficiency. \n\n**Conclusion:**\nImplementing a feature to exclude specific

By adopting industry best practices for both temporary and long-term credentials, we can significantly reduce the potential risks of credential leakage and improve the overall security posture of MCP Server.\n\n---\n\n### 1. Temporary Credentials\n\nMCP Server often needs to access data sources using temporary, rotatable credentials. To ensure secure and efficient management of these credentials, I recommend implementing the following industry best practices:\n\n#### A. Workload Identity-Based Access\n\nWhen MCP Server acts as a workload to access data sources, the following mechanisms should be adopted:\n- **GCP Workload Identity Federation:** Allow workloads to authenticate directly with GCP services without relying on long-term credentials.\n- **Azure Entra Client Credential Auth:** Use Azure Entra (formerly Azure AD) for secure authentication and token issuance.\n- **AWS EC2 Instance Metadata:** Leverage AWS EC2 instance metadata for retrieving temporary credentials.\n- **Kubernetes Integration with AWS STS:** Implement `AssumeRoleWithWebIdentity` to enable Kubernetes service accounts to exchange tokens for AWS STS credentials.\n\nThese approaches ensure that credentials are short-lived, automatically rotated, and tied to specific workloads, minimizing the risk of misuse.\n\n#### B. User Identity-Based Access\n\nWhen MCP Server acts on behalf of a user (e.g., Claude Desktop Client or Cursor Client calling a locally deployed MCP Server), the following best practice should be implemented:\n- **OAuth 2.0 Device Flow:** Use OAuth 2.0 Device Flow to securely authenticate users and obtain access tokens without exposing credentials.\n\n---\n\n### 2. Long-Term Credentials\n\nIn cases where long-term credentials are unavoidable (e.g., legacy systems or APIs that rely on static credentials like username/password or API keys), MCP Server should enforce strict security measures:\n- **Secure Storage:** Store long-term credentials in a secure vault system such as HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, or GCP Secret Manager.\n- **Access Control:** Implement strict access controls and audit logging for credential retrieval and usage.\n- **Encryption:** Ensure credentials are encrypted at rest and in transit.\n\n---\n\n### Proposal\n\nTo align MCP Server with industry standards and enhance its security, I propose the following:\n1. Officially adopt the best practices outlined above for managing temporary and long-term credentials.\n2. Open-source the implementation of these security features to enable community collaboration, transparency, and continuous improvement.\n\nBy open-sourcing the implementation, the MCP community can actively contribute to and review the security mechanisms, ensuring a robust and trustworthy solution.\n\n---\n\n### Next Steps\n\n1. Evaluate the feasibility of integrating the suggested mechanisms for temporary and long-term credential management.\n2. Develop a roadmap for implementing secure credential storage and access control.\n3. Open-source the implementation to foster community involvement and feedback.\n\nI believe these improvements will significantly strengthen MCP Server's security and align it with industry best practices. I look forward to hearing the community's thoughts and feedback on this proposal!\n\nBest regards", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/754/reactions", "total_count": 20, "+1": 20, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/751", "id": 2900574542, "node_id": "I_kwDONRaG_86s40FO", "number": 751, "title": "long output", "user": { "login": "Skywalker-Harrison", "id": 63527319, "node_id": "MDQ6VXNlcjYzNTI3MzE5", "avatar_url": "https://avatars.githubusercontent.com/u/63527319?v=4", "gravatar_id": "", "url": "https://api.github.com/users/Skywalker-Harrison", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432740, "node_id": "LA_kwDONRaG_88AAAABzvmeJA", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/enhancement", "name": "enhancement", "color": "a2eeef", "default": true, "description": "New feature or request" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 0, "created_at": "2025-03-06T14:29:26Z", "updated_at": "2025-03-06T14:29:26Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "# Feature Request: Support for Long Text Output in MCP on Claude Desktop\n\n## Problem Description\nCurrently, when using MCP on Claude Desktop, if the length of the text output exceeds 20,000 characters, an error occurs. The error is similar to the one described in [issue #719](https://github.com/modelcontextprotocol/servers/issues/719), and an \"Unexpected End JSON\" error pops up. This limitation is frustrating when working with long text outputs, as it interrupts the workflow and prevents the completion of tasks that require extensive text generation.\n\n## Desired Solution\nI would like MCP on Claude Desktop to support long text outputs without encountering errors. Specifically, the system should be able to handle text outputs significantly longer than 20,000 characters, ensuring smooth and uninterrupted operation.\n\n## Alternatives Considered\n- **Chunking the Output:** Manually splitting the text into smaller chunks to avoid hitting the character limit.

Please describe.**\nI've been using `mcp-server-git` for local development, it's freakin' awesome, great job everyone. But I don't see `git_merge` as a tool, I'm wondering if there is any good reason why it's not included at the moment? I can do `checkout`, `status`, `commit`, etc. so it seems like it would be a great thing for my local workflow.\n\n**Describe the solution you'd like**\nAdd a `git_merge` tool that takes these inputs:\n\n`repo_path` (string): Path to Git repository\n`source_branch` (string): Name of branch to merge FROM. (`git merge foo`) if `source_branch` = `foo`\n`target_branch` (string): Name of the branch to merge INTO (by default, the current working branch)\n`ff-only` (boolean): Whether to require the merge to be `ff-only` (`true` by default)\n`squash` (boolean): Whether the merge should be a `squash` (`false` by default)\nReturns: Confirmation of `git merge --ff-only` command, or a message describing why the merge failed (merge conflict encountered, merge is not fast-forward when `ff-only = true`, `source_branch` does not exist), etc.\n\nIf any of these conditions are not met, or there are conflicts, the merge will be aborted with `git merge --abort`.\n\n**Describe alternatives you've considered**\nNone (or just do it manually).\n\n**Additional context**\nFor an initial implementation, due to the nuances of merging, the tool can be configured to ONLY allow `ff-only` from `source_branch` to `target_branch`, where `target_branch` is the current checked-out branch, and will fail if there are any conflicts, if the merge is not fast-forward, if `target_branch` is not the current branch (as revealed by `git_status`), etc. Basically, this will ONLY succeed if I have a local branch `dev` and I am on `main` and I can successfully run `git merge dev --ff-only`. I can imagine a lot of ways to enhance this tool, but this would still be a really useful addition, even in this primitive form.\n", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/659/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/644", "id": 2866339904, "node_id": "I_kwDONRaG_86q2OBA", "number": 644, "title": "\"Not connected\" error", "user": { "login": "KikeVen", "id": 18605904, "node_id": "MDQ6VXNlcjE4NjA1OTA0", "avatar_url": "https://avatars.githubusercontent.com/u/18605904?v=4", "gravatar_id": "", "url": "https://api.github.com/users/KikeVen", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" }, "1": { "id": 8359497168, "node_id": "LA_kwDONRaG_88AAAAB8kPN0A", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/server-sequentialthinking", "name": "server-sequentialthinking", "color": "D4C5F9", "default": false, "description": "Reference implementation for the Sequential Thinking MCP server - src/sequentialthinking" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 9, "created_at": "2025-02-20T14:32:33Z", "updated_at": "2025-07-28T02:39:55Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "On Windows 11:\n\nI was unable to successfully set up the Sequential Thinking MCP server.

Open Browser and go to [http://localhost:5173](http://localhost:5173)\n7. Select \"STDIO\" and click Connect\n8. List Tools\n9.

Currently, permission prompts are triggered only after a failed file access attempt, leading to a jarring experience where:\r\n\r\n1. User requests to read a file using `read_file` tool\r\n2. Operation fails due to lack of permissions\r\n3. Claude app prompts for system permissions\r\n4. User has to retry the operation\r\n\r\n## Impact\r\nThis creates a poor user experience where:\r\n- Operations fail before permissions are established\r\n- Users see error messages before permission prompts\r\n- Multiple permission prompts might appear for different files\r\n- Operations need to be manually retried after granting permissions\r\n\r\n## Proposed Solution\r\nAdd a new `check_permissions` tool to the Filesystem MCP server that would:\r\n- Allow proactive permission checking before file operations\r\n- Trigger any needed system permission prompts upfront\r\n- Return clear status about which paths are accessible\r\n- Enable better error handling and user guidance\r\n\r\n### Implementation Details\r\n- New tool: `check_permissions`\r\n- Input: Array of paths to validate\r\n- Output: Mapping of paths to their permission status\r\n- Validates both MCP server allowed directories and system-level permissions\r\n- Triggers OS permission prompts in a controlled manner\r\n\r\n## Benefits\r\n- More predictable permission flow\r\n- Better user experience\r\n- Clearer feedback about access status\r\n- Reduced need for error recovery\r\n- Maintains separation of concerns within MCP architecture\r\n\r\n## Notes\r\nWhile the ideal fix might involve changes to the Claude desktop app itself, this server-side solution provides a workable improvement within the current architecture.", "closed_by": null, "reactions": { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/239/reactions", "total_count": 1, "+1": 1, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 }, "performed_via_github_app": null, "state_reason": null, "pinned_comment": null, "linked_prs": [] }, { "url": "https://api.github.com/repos/modelcontextprotocol/servers/issues/235", "id": 2719236429, "node_id": "I_kwDONRaG_86iFEFN", "number": 235, "title": "filesystem couldn't use the network mapped driver name, only the unc path in windows 11 23h2", "user": { "login": "dave2nian", "id": 166886426, "node_id": "U_kgDOCfJ8Gg", "avatar_url": "https://avatars.githubusercontent.com/u/166886426?v=4", "gravatar_id": "", "url": "https://api.github.com/users/dave2nian", "type": "User", "user_view_type": "public", "site_admin": false }, "labels": { "0": { "id": 7767432729, "node_id": "LA_kwDONRaG_88AAAABzvmeGQ", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/bug", "name": "bug", "color": "d73a4a", "default": true, "description": "Something isn't working" }, "1": { "id": 8351171797, "node_id": "LA_kwDONRaG_88AAAAB8cTE1Q", "url": "https://api.github.com/repos/modelcontextprotocol/servers/labels/server-filesystem", "name": "server-filesystem", "color": "D4C5F9", "default": false, "description": "Reference implementation for the Filesystem MCP server - src/filesystem" } }, "state": "open", "locked": false, "assignee": null, "assignees": {}, "milestone": null, "comments": 2, "created_at": "2024-12-05T03:43:04Z", "updated_at": "2025-07-05T09:42:45Z", "closed_at": null, "author_association": "NONE", "type": null, "active_lock_reason": null, "sub_issues_summary": { "total": 0, "completed": 0, "percent_completed": 0 }, "issue_dependencies_summary": { "blocked_by": 0, "total_blocked_by": 0, "blocking": 0, "total_blocking": 0 }, "body": "**Describe the bug**\r\nin my windows 11 23h2, \r\n\r\n`C:\\net use z:\r\nLocal name Z:\r\nRemote name \\\\davens\\Multimedia\r\nResource type Disk\r\nStatus OK\r\n# Opens 2\r\n# Connections 1\r\nThe command completed successfully.`\r\n\r\nclaude_decktop_config.json content as below: \r\n`{\r\n \"mcpServers\": {\r\n \"filesystem\": {\r\n \"command\": \"npx\",\r\n \"args\": [ \r\n \"-y\", \r\n \"@modelcontextprotocol/server-filesystem\", \r\n \"Z:\\\\2024-MyProgramFiles\"\r\n ]\r\n }\r\n }\r\n}` \r\n\r\nif I used Z: drive in the claude_decktop_config.json, z: or Z: .

"## Description\nThis PR adds [Spring Boot Swagger MCP](https://github.com/Neo1228/spring-boot-starter-swagger-mcp) to the Community Servers list.\n\n## Motivation and Context\nSpring Boot is the most popular framework for enterprise Java development. This library allows developers to instantly expose their existing APIs as MCP tools without writing any adapter code, bridging the gap between traditional backend services and AI agents.\n\n## Key Features\n- **Zero Boilerplate**: Uses existing \\@RestController\\ and \\@Operation\\ annotations.\n- **Auto-Discovery**: Dynamically generates tool specifications from the running application.\n- **Safe by Default**: Configurable human-in-the-loop confirmation for side-effect operations (POST/PUT/DELETE).\n- **Advanced Context**: Built-in meta-tools to help LLMs explore and understand the API hierarchy.\n\n## How Has This Been Tested?\nTested with:\n- Claude Desktop\n- MCP Inspector\n- Various Spring Boot applications using \\springdoc-openapi\\.\n\n## Checklist\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\n- [x] My changes follows MCP security best practices\n- [x] I have updated the server's README accordingly\n- [x] I have tested this with an LLM client\n- [x] My code follows the repository's style guidelines\n- [x] New and existing tests pass locally\n- [x] I have added appropriate error handling\n- [x] I have documented all environment variables and configuration options\n\n## Links\n- Repository: https://github.com/Neo1228/spring-boot-starter-swagger-mcp\n- Documentation:

(where the entity is the from endpoint) in addition to relations between opened nodes\n- Updated tool description to reflect new behavior\n- Updated tests to match new expected behavior\n\n## Why\n\nPreviously, open_nodes only returned relations where both endpoints were in the requested node list. This made it impossible to traverse the graph from specific nodes without reading the entire graph.\n\nNow, when you open a node, you also get its outgoing relations, enabling graph traversal.\n\n## Test\n\nAll tests pass (42/42)", "created_at": "2026-02-14T15:17:48Z", "updated_at": "2026-02-14T15:17:48Z", "closed_at": null, "merged_at": null, "merge_commit_sha":

This PR adds comprehensive test coverage (272 tests), fixes critical architectural issues, and implements proper validation, error handling, and resource management.\n\n## Key Improvements\n\n### Test Coverage (0 → 272 tests)\n- **17 test files** covering all components\n- **Integration tests**: Server behavior, performance benchmarks\n- **Unit tests**: All services, utilities, and edge cases\n- **Test helpers**: Factories and mocks for consistent testing\n- Added Vitest configuration with proper TypeScript support\n\n### Architectural Fixes\n\n**Race Condition in Rate Limiting**\n- Fixed race condition where concurrent requests could bypass rate limits\n- Moved session recording to happen atomically with rate limit check\n- Added 7 comprehensive tests covering concurrent scenarios\n\n**Data Consistency (Single Source of Truth)**\n- Eliminated duplicate branch tracking between metrics and storage\n- Metrics now queries storage directly for branch counts\n- Prevents state divergence between components\n\n**Session ID Validation**\n- Added upfront validation with clear error messages\n- Prevents silent replacement of invalid session IDs\n- Preserves user intent with fail-fast behavior\n- Comprehensive tests for valid/invalid formats and edge cases\n\n**Efficient Timestamp Tracking**\n- Replaced O(n) array operations with O(1) CircularBuffer\n- Eliminated inefficient cleanup algorithms\n- Added proper 60-second window filtering\n\n**Dead Code Elimination**\n- Removed unused methods and incomplete APIs\n- Cleaned up redundant code paths\n\n### Configuration & Environment\n- Made health check thresholds configurable via environment variables\n- Centralized configuration management with proper validation\n- Added comprehensive environment variable documentation\n- Fixed stateful regex patterns that caused intermittent failures\n\n### Security & Validation\n- **Implemented rate limiting enforcement** (was documented but not enforced)\n- Sliding-window rate limiting with per-session tracking\n- Enhanced input sanitization with proper pattern detection\n- Improved session validation and generation\n- Added configurable blocked patterns\n\n### Error Handling & Logging\n- Structured logging with circular reference detection\n- Proper error propagation and classification\n- Try/catch guards around formatting operations\n- No more silent error swallowing\n- Clear error messages for validation failures\n\n### Resource Management\n- Added proper `destroy()` methods to all services\n- Idempotent cleanup (safe to call multiple times)\n- Automatic resource cleanup on shutdown\n- Memory-bounded data structures (CircularBuffer, capped Sets)\n\n### Performance Optimizations\n- CircularBuffer for O(1) operations (response times, timestamps)\n- Capped collections to prevent unbounded growth\n- Optimized cleanup algorithms\n- Efficient filtering and queries\n\n### Code Quality\n- Added ESLint configuration with TypeScript support\n- Added Prettier for consistent formatting\n- Required `destroy()` methods on all storage interfaces\n- Changed session stats to use numeric timestamps\n- Added error rate clamping (0-100%)\n- Fixed type safety issues throughout codebase\n\n## New Components\n\n### Core Services\n- `circular-buffer.ts` - Efficient fixed-size buffer implementation\n- `session-tracker.ts` - Centralized session lifecycle management\n- `health-checker.ts` - Comprehensive health monitoring\n- `metrics.ts` - Request and thought metrics collection\n- `logger.ts` - Structured logging with sanitization\n- `security-service.ts` - Validation, sanitization, rate limiting\n- `state-manager.ts` - Bounded thought history management\n\n### Configuration & Infrastructure\n- `config.ts` - Centralized configuration with environment variable support\n- `container.ts` - Dependency injection container\n- `interfaces.ts` - TypeScript interfaces for all services\n- `formatter.ts` - Console output formatting\n- `error-handlers.ts` - Composite error handling\n- `errors.ts` - Custom error classes\n\n## Test Files Added\n\n### Unit Tests\n- `circular-buffer.test.ts` (20 tests) - Buffer operations and edge cases\n- `config.test.ts` (26 tests) - Configuration loading and validation\n- `logger.test.ts` (24 tests) - Logging and sanitization\n- `security-service.test.ts` (22 tests) - Validation and rate limiting\n- `health-checker.test.ts` (15 tests) - Health check logic\n- `metrics.test.ts` (14 tests) - Metrics collection\n- `formatter.test.ts` (13 tests) - Output formatting\n- `session-validation.test.ts` (13 tests) - Session ID validation\n- `state-manager.test.ts` (17 tests) - Thought history management\n- `container.test.ts` (11 tests) - Dependency injection\n- `storage.test.ts` (7 tests) - Storage utilities\n- `race-condition.test.ts` (7 tests) - Concurrent access scenarios\n- `branch-tracking.test.ts` (6 tests) - Branch consistency\n- `error-handler.test.ts` (4 tests) - Error handling\n\n### Integration Tests\n- `server.test.ts` (52 tests) - End-to-end server behavior\n- `performance.test.ts` (6 tests) - Performance benchmarks\n- `timestamp-tracking.test.ts` (16 tests) - Time-based filtering\n\n## Verification\n\n✅ **TypeScript**: 0 compilation errors \n✅ **ESLint**: 0 linting errors \n✅ **Tests**: 272/272 passing \n✅ **No breaking changes**: All changes are internal improvements\n\n## Changes by Category\n\n### Modified Core Files\n- `index.ts` - Updated tool definition and initialization\n- `lib.ts` - Refactored with proper service composition\n- `package.json` - Added dev dependencies for testing and linting\n- `vitest.config.ts` - Test configuration\n- `README.md` - Updated documentation with environment variables\n\n### Configuration Files Added\n- `.eslintrc.cjs` - TypeScript-aware linting rules\n- `.prettierrc.json` - Code formatting rules\n\nAll changes maintain backward compatibility with existing usage patterns.\n\n## Docker Fix\n\n**Critical Bug Fixed**: The Dockerfile was non-functional due to missing build step.\n\n**Problem**: \n- Line 10 ran `npm ci --ignore-scripts --omit-dev` which skipped the TypeScript compilation\n- The `dist/` directory was never created\n- Docker images appeared to build successfully but were non-functional\n\n**Solution**:\n- Replaced with `RUN npm run build` to properly compile TypeScript\n- Now the build process works correctly:\n 1. Install dependencies (including devDependencies)\n 2. Compile TypeScript → JavaScript (`npm run build`)\n 3. Copy built `dist/` to release image\n 4. Install only production dependencies in release\n\n**Impact**: Docker installation method now actually works as documented.\n\nCredits: Based on PR #2965 by @bruno-t-cardoso (open for 3 months)\n",

"public", "site_admin": false }, "body": "## Summary\n\nFixes #2912 — The `SequentialThinkingServer` stores all thoughts in memory arrays (`thoughtHistory` and `branches`) that grow without bound across the server process lifetime. In long-running sessions (6-8+ hours of frequent use), this can lead to **10GB+ RAM consumption**.\n\n## Root Cause\n\n`thoughtHistory: ThoughtData[]` and `branches: Record` are append-only — thoughts are pushed but never removed or trimmed. Since the server is a long-lived stdio process, memory accumulates indefinitely.\n\n## Changes\n\n### 1. Configurable max history with auto-trimming (`lib.ts`)\n- Added `SEQUENTIAL_THINKING_MAX_HISTORY` environment variable (default: `1000`)\n- When thought count exceeds the limit, oldest thoughts are trimmed via `splice()`\n- This bounds memory usage to a predictable maximum regardless of session length\n\n### 2. Explicit `clearHistory()` method (`lib.ts`)\n- New public method that resets both `thoughtHistory` and `branches` to empty\n- Returns metadata about what was cleared (previous thought/branch counts)\n\n### 3. New `sequentialthinking_clear` tool (`index.ts`)\n- Registers a tool that clients can invoke to explicitly free memory\n- Useful between distinct thinking sessions within the same server process\n\n### 4. Documentation (`README.md`)\n- Added environment variables table documenting both `DISABLE_THOUGHT_LOGGING` and the new `SEQUENTIAL_THINKING_MAX_HISTORY`\n\n### 5. Tests (`lib.test.ts`)\n- `clearHistory` — verifies thoughts and branches are fully reset\n- Memory management — verifies history trimming at default limit\n- Environment variable — verifies custom `SEQUENTIAL_THINKING_MAX_HISTORY` is respected\n\n## Testing\n\nAll 17 tests pass:\n```\n✓ __tests__/lib.test.ts (17 tests) 4ms\nTest Files 1 passed (1)\n Tests 17 passed (17)\n```\n\n## Design Decisions\n\n- **Default limit of 1000**: Conservative — retains substantial context while preventing runaway growth. A single thought is typically a few hundred bytes of text, so 1000 thoughts ≈ a few hundred KB.\n- **Trim oldest first**: Most recent thoughts are the most relevant for ongoing reasoning. Oldest thoughts are the least likely to be referenced.\n- **Separate clear tool**: Allows explicit memory management without losing the auto-trim safety net.", "created_at": "2026-02-11T08:36:08Z",

"body": "## Summary\n\n- **Restores** the archived `src/gdrive/` server (removed in May 2025)\n- **Fixes** search results to include file IDs — the Drive API fetches `files(id, name, mimeType, ...)` but the output only included name and MIME type, making results unusable for downstream operations\n- **Adds** a `download` tool that saves files to a local temp directory instead of returning base64 blobs via the resource handler, which overflow LLM context windows\n- **Fixes** OAuth token auto-refresh — the server was creating `new google.auth.OAuth2()` without client credentials, so the refresh_token was unusable once the access_token expired (~1 hour). Now reads client_id/secret from the OAuth keys file.\n- **Makes MCP resources opt-in** via `GDRIVE_ENABLE_RESOURCES` env var — some MCP clients (e.g., Gemini CLI) call `resources/list` during initialization, which triggers `drive.files.list()` and can hang. Default is tools-only mode (search + download) for cross-client compatibility.\n\n## Motivation\n\nThe gdrive server is essential for LLM workflows that need to search and read Drive files (especially PDFs, images, and other binary formats). Two prior community PRs attempted similar improvements:\n\n- **#1092** — \"Add gdrive_read_file tool and improve search results\"\n- **#1353** — \"Transition to Tool-Based Architecture with Enhanced File Handling\"\n\nBoth were closed when the server was archived. The underlying issues remain: without file IDs in search output, clients can't act on results; without a download tool, binary files either overflow context (base64 blobs) or are inaccessible.\n\n## Changes\n\n### 1. Search output includes file IDs\n\n```typescript\n// Before:\n`${file.name} (${file.mimeType})`\n\n// After:\n`${file.name} (${file.mimeType}) [id:${file.id}]`\n```\n\n### 2. New `download` tool\n\n- Takes a `fileId` (from search results) and saves the file to a local directory\n- Google Workspace files are auto-exported: Docs → Markdown, Sheets → CSV, Presentations → Plain text, Drawings → PNG\n- Binary files (PDFs, images, etc.) saved as-is\n- Download directory configurable via `GDRIVE_DOWNLOAD_DIR` env var (default: `/tmp/gdrive-downloads`)\n- Filenames are sanitized for filesystem safety\n\n### 3. OAuth token auto-refresh fix\n\nThe original server created `new google.auth.OAuth2()` without `client_id` or `client_secret`. This meant the `refresh_token` in the stored credentials was unusable — when the access token expired (~1 hour), Google's token endpoint returned `invalid_request` because the refresh grant requires client credentials. Now reads `client_id`/`client_secret` from the same OAuth keys file used during the initial auth flow (`GDRIVE_OAUTH_PATH`) and passes them to the `OAuth2` constructor.\n\n### 4. MCP resources opt-in (`GDRIVE_ENABLE_RESOURCES`)\n\nSome MCP clients invoke `resources/list` during initialization, which triggers `drive.files.list()` and can hang or timeout. Resources are now disabled by default — the server advertises only `tools` capability. Set `GDRIVE_ENABLE_RESOURCES=true` to re-enable `ListResources` and `ReadResource` handlers.\n\nThis is a clean capability negotiation: the server honestly advertises what it supports based on the env var, and the MCP SDK validates that handlers match declared capabilities.\n\n### 5. Standalone build\n\n- `tsconfig.json` is self-contained (no longer extends root tsconfig)\n- Version bumped from 0.6.2 → 0.7.0\n\n## Test plan\n\n- [x] TypeScript compiles cleanly with `npm run build`\n- [x] `search` returns file IDs in output format `[id:...]`\n- [x] `download` saves binary files (PDFs) to local temp directory\n- [x] `download` exports Google Docs as markdown\n- [x] Filename sanitization handles special characters\n- [x] OAuth auto-refresh works after access token expiry (tested with expired token + valid refresh_token)\n- [x] Server starts in tools-only mode (default, no `GDRIVE_ENABLE_RESOURCES`)\n- [x] Server starts with resources enabled (`GDRIVE_ENABLE_RESOURCES=true`)\n- [x] Tested with Claude Code and Gemini CLI — both connect and use search/download tools successfully\n\n## Notes\n\nWe've been running these fixes in production for Claude Code and Gemini CLI MCP workflows (searching and reading ~300 signed compliance PDFs on Google Drive). Happy to maintain this server going forward.\n\nContact: aaron@mivest.io\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)", "created_at": "2026-02-08T07:17:07Z", "updated_at":

`openNodes()` and `searchNodes()` filter relations using `&&` (require BOTH endpoints to be in the result set). This means if you call `open_nodes([\"A\"])` and there's a relation `A → B`, it gets silently dropped because `B` isn't in the filtered set.\n\n**Fix:** Changed the relation filter from `&&` to `||` — include any relation where **at least one** endpoint is in the result set. This matches standard graph-query semantics: opening a node should reveal all its edges, not just edges to other opened nodes.\n\n#### Before (broken)\n```\nopen_nodes([\"2025-12-17\"])\n→ entities: [2025-12-17], relations: [] // relations silently dropped!\n```\n\n#### After (fixed)\n```\nopen_nodes([\"2025-12-17\"])\n→ entities: [2025-12-17], relations: [{from: \"2025-12-17\", to: \"incident/example\", ...}]\n```\n\n### Changes\n\n- `src/memory/index.ts`: Changed `&&` → `||` in relation filtering for both `openNodes()` and `searchNodes()`\n- `src/memory/__tests__/knowledge-graph.test.ts`: Updated existing tests and added new cases:\n - Outgoing relations to nodes not in the open set\n - Incoming relations from nodes not in the open set\n - Relations connected to a single opened node (both directions)\n - `searchNodes` returning outgoing relations to unmatched entities\n\n### Test plan\n\n- [x] All 45 existing tests pass (`vitest run`)\n- [x] New tests verify outgoing/incoming relations are returned for single-node queries\n- [x] `read_graph` behavior unchanged (returns all relations)\n- [x] Empty node list still returns empty graph\n- [x] Non-existent nodes still return empty result\n\n---\n\n## AI View (DCCE Protocol v1.0)\n\n### Metadata\n- **Generator**: Claude (Anthropic) via Cursor IDE\n- **Methodology**: AI-assisted development with human oversight and review\n\n### AI Contribution Summary\n- Solution design and implementation\n\n### Verification Steps Performed\n1.

This adds a fallback that uses fs.cp() + fs.unlink() when EPERM is encountered, allowing edits to succeed even when the file is open.\r\n\r\nFixes #3199\r\n\r\n\r\n\r\n## Description\r\nAdds atomicReplaceFile() helper that falls back to fs.cp() when fs.rename() fails with EPERM.\r\n\r\n## Publishing Your Server\r\n\r\n**Note: We are no longer accepting PRs to add servers to the README.** Instead, please publish your server to the [MCP Server Registry](https://github.com/modelcontextprotocol/registry) to make it discoverable to the MCP ecosystem.\r\n\r\nTo publish your server, follow the [quickstart guide](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx). You can browse published servers at [https://registry.modelcontextprotocol.io/](https://registry.modelcontextprotocol.io/).\r\n\r\n## Server Details\r\n - Server: filesystem\r\n - Changes to: tools (edit_file, write_file)\r\n\r\n## Motivation and Context\r\nOn Windows, files open in editors (VS Code, Notepad, etc.) are locked. The current fs.rename() approach fails with EPERM when trying to atomically replace these locked files. This prevents users from editing files they have open.\r\n\r\n## How Has This Been Tested?\r\nUnit tests added for EPERM fallback behavior. All 46 lib.test.ts tests pass.\r\n\r\n## Breaking Changes\r\nNone - existing behavior unchanged on Linux/macOS. Windows users will now have edits succeed where they previously failed.\r\n\r\n## Types of changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [ ] I have updated the server's README accordingly\r\n- [ ] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [ ] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n", "created_at": "2026-02-07T00:25:13Z", "updated_at": "2026-02-07T00:25:13Z", "closed_at": null,

Description\n\nThis PR implements proper cross-process file locking for the memory server using `proper-lockfile` to ensure atomic read-modify-write operations across multiple MCP server instances.\n\n**Key changes:**\n- Add `proper-lockfile` dependency for cross-process file locking\n- Wrap all write operations (`createEntities`, `deleteEntities`, `createRelations`, `deleteRelations`, `addObservations`, `deleteObservations`) in `withLock()` to ensure atomic read-modify-write\n- Use `write-file-atomic` for more robust atomic file writes\n- Add comprehensive lock tests validating consistency under heavy concurrent writes\n\n### Why PR #3060's in-memory lock solution is insufficient\n\nPR #3060 attempts to fix Issue #2579's race condition using an **in-memory Promise-based lock**. While this works for concurrent operations within a single process, it fundamentally misses the real-world deployment model:\n\n**MCP servers using stdio transport are spawned as separate processes per client.**\n\n```\n┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐\n│ Claude Code │ │ Claude Code │ │ Claude Code │\n└────────┬────────┘ └────────┬────────┘ └────────┬────────┘\n │ │ │\n ▼ ▼ ▼\n┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐\n│mcp-server-memory│ │mcp-server-memory│ │mcp-server-memory│\n│ (Process A) │ │ (Process B) │ │ (Process C) │\n│ [In-memory lock]│ │ [In-memory lock]│ │ [In-memory lock]│\n└────────┬────────┘ └────────┬────────┘ └────────┬────────┘\n │ │ │\n └──────────┬──────────┴──────────┬──────────┘\n ▼ ▼\n ┌─────────────────────────────────┐\n │ memory.json │\n │ (STILL VULNERABLE TO RACES!) │\n └─────────────────────────────────┘\n```\n\nPR #3060 acknowledges this limitation:\n> \"⚠️ Important: This is a Temporary Measure for Single Editor Usage\"\n> \"If you use multiple LLM clients or editors concurrently with the same memory file, you may still experience race conditions.\"\n\nThis multi-client scenario is the **default use case** for many users, not an edge case.\n\n## Server Details\n- Server: memory\n- Changes to: tools (all write operations now wrapped with cross-process file lock)\n\n## Motivation and Context\n\nThe memory server experiences file corruption when multiple MCP server instances (spawned by different AI clients) attempt concurrent writes to the same `memory.json` file. \n\nThis is critical because:\n1. Many users run multiple AI clients (Claude Desktop, VS Code, Cursor, CLI) simultaneously\n2. Each client spawns its own mcp-server-memory process via stdio\n3. All processes share the same memory file, causing race conditions and data corruption\n4. The in-memory lock in PR #3060 only protects within a single process, not across processes\n\n## How Has This Been Tested?\n\n### 1. Single-process concurrent writes (10,000 operations)\n- **File:** `knowledge-graph.test.ts`\n- **Scenario:** 10,000 concurrent `createEntities` calls within a single process\n- **Purpose:** Validates that the lock mechanism correctly serializes rapid async operations and prevents race conditions from Promise concurrency\n\n### 2. Multi-process concurrent writes (5 processes × 2,000 = 10,000 operations)\n- **File:** `multi-process-lock.test.ts` \n- **Scenario:** Spawns 5 separate Node.js processes, each writing 2,000 entities simultaneously to the same file\n- **Purpose:** Simulates the real-world MCP deployment where multiple AI clients spawn independent `mcp-server-memory` processes via stdio transport\n\n### Additional testing:\n- Verified lock acquisition and release under heavy contention\n- Tested with multiple simultaneous MCP client connections to same memory file\n- All existing tests continue to pass\n\n## Breaking Changes\n\nNo breaking changes:\n- Same API and tool signatures\n- Same file format (JSONL)\n- No configuration changes required\n\n## Types of changes\n- [x] Bug fix (non-breaking change which fixes an issue)\n- [ ] New feature (non-breaking change which adds functionality)\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\n- [ ] Documentation update\n\n## Checklist\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\n- [x] My changes follows MCP security best practices\n- [x] I have updated the server's README accordingly\n- [x] I have tested this with an LLM client\n- [x] My code follows the repository's style guidelines\n- [x] New and existing tests pass locally\n- [x] I have added appropriate error handling\n- [x] I have documented all environment variables and configuration options\n\n## Additional context\n\n### Related Issues and PRs\n- Fixes #2579 - Race condition causing \"Unexpected non-whitespace character after JSON\" errors\n- Supersedes #3060 - In-memory lock is insufficient for multi-process stdio scenarios\n\n### Why `proper-lockfile`?\n\n| Approach | Cross-process safe | External service | Complexity |\n|----------|-------------------|------------------|------------|\n| In-memory Promise lock (#3060) | No | No | Low |\n| `proper-lockfile` (this PR) | Yes | No | Low |\n| SQLite | Yes | No | Medium |\n| Redis | Yes | Yes | High |\n\n`proper-lockfile` provides the best balance of correctness and simplicity - true cross-process safety without external dependencies

external drive), the server now:\n\n- Warns about each unavailable directory and skips it\n- Continues starting with all available directories \n- Only fails if NO directories are accessible\n\n## Changes\n- Modified startup validation in `src/filesystem/index.ts` to collect unavailable directories and filter them out instead of calling `process.exit(1)` on the first failure\n- Added clear warning messages showing which directories were skipped\n- Server exits with error only when zero directories are accessible\n\n## Testing\n- All 139 existing tests pass\n- Manual testing confirms:\n - Server starts with mixed valid/invalid directories (warns and continues)\n - Server fails gracefully with all invalid directories (helpful error message)\n\n## Impact\nThis makes the filesystem MCP server more resilient for setups involving:\n- Network shares/NAS devices\n- External drives\n- Mounted volumes\n- Any path that might be temporarily unavailable\n\nFixes #3232", "created_at":

"body": "## Summary\n\nAdds a `time_` prefix to the Time MCP server tool names for consistency with other MCP servers:\n\n- `get_current_time` → `time_get_current`\n- `convert_time` → `time_convert`\n\n## Motivation\n\nThis follows the naming convention used by other MCP servers (e.g., `git_status`, `git_commit`, `git_diff`) and makes it easier to identify related tools when multiple MCP servers are registered with a client.\n\nAs noted in [issue #3201](https://github.com/modelcontextprotocol/servers/issues/3201), users integrating multiple MCP servers see tool names like:\n- `MCP_DOCKER_convert_time`\n- `MCP_DOCKER_get_current_time`\n\nWith this change, the tools become:\n- `MCP_DOCKER_time_get_current`\n- `MCP_DOCKER_time_convert`\n\nThis makes it immediately clear these tools belong to the Time server.\n\n## Changes\n\n- Updated tool name enum values in `server.py`\n- Updated README documentation and examples\n\n## Breaking Change Notice\n\n⚠️ This is a breaking change for existing users of the Time MCP server. Any automation or configuration referencing the old tool names (`get_current_time`, `convert_time`) will need to be updated.\n\nCloses #3201", "created_at": "2026-01-31T04:44:40Z", "updated_at":

popular coding agent that supports MCP. Currently, only `sequentialthinking` documents how to add it via Codex CLI.

This provides clear visibility into how the reference implementation evolves over time—useful for SDK compliance validation, catching unintended regressions, and reviewing PRs that modify the server interface.\n\n## Motivation\n\nThe Everything server is the reference implementation that exercises all MCP protocol features. Changes to its public interface (tools, resources, prompts, capabilities) often signal:\n- New protocol features being demonstrated\n- SDK updates affecting server behavior \n- Potential breaking changes\n\nCurrently there's no automated way to see these changes at a glance. This workflow surfaces them directly in the GitHub Actions summary.\n\n**Related discussion:** [modelcontextprotocol/inspector#1034](https://github.com/modelcontextprotocol/inspector/issues/1034) - Interest in using mcp-server-diff for SDK compliance testing with the Everything server.\n\n## What the workflow does\n\n1. **Triggers** on PRs and pushes affecting `src/everything/`\n2. **Compares** current branch against merge-base (PRs) or previous commit (pushes)\n3. **Generates** a diff report showing changes to tools, resources, prompts, and capabilities\n4. **Supports** manual `workflow_dispatch` for comparing any two refs (commits, tags, branches)\n\n## Example output\n\nHere's a real diff between commit `737ce98` and the current HEAD of the Everything server:\n\n```diff\n--- base/initialize.json\n+++ target/initialize.json\n\n+ capabilities.tasks: {\"cancel\":{},\"list\":{},\"requests\":{\"tools\":{\"call\":{}}}}\n```\n\n```diff\n--- base/tools.json\n+++ target/tools.json\n\n+ tools[simulate-research-query]: {\"description\":\"Simulates a deep research operation...\"}\n```\n\nThis clearly shows the new Tasks capability and the `simulate-research-query` tool that were added.\n\n## Real-world example\n\nSee the MCP diff action in use on [github/github-mcp-server](https://github.com/github/github-mcp-server/actions/runs/21258183290) - this workflow run shows interface changes from the \"Generate server instructions in Inventory\" PR.\n\n## Workflow features\n\n- ✅ **Minimal permissions** (`contents: read` only)\n- ✅ **Pinned action versions** with SHA references\n- ✅ **Path filtering** - only runs when Everything server changes\n- ✅ **Manual trigger** - compare any refs via workflow_dispatch\n- ✅ **Clear summary** - results appear directly in GitHub Actions UI\n\n## Testing\n\nThe workflow uses [SamMorrowDrums/mcp-server-diff](https://github.com/SamMorrowDrums/mcp-server-diff) which is also available as a CLI:\n\n```bash\n# Try it locally\nnpx mcp-server-diff@latest -b \"node dist/index.js stdio\" -t \"node dist/index.js stdio\" -o markdown\n```\n", "created_at": "2026-01-28T16:58:44Z", "updated_at": "2026-02-02T22:18:32Z", "closed_at": null, "merged_at": null, "merge_commit_sha":

false }, "body": "## Summary\r\n\r\nFixes #3253\r\n\r\n**Problem**\r\nOn macOS, `/tmp` is a symlink to `/private/tmp`. When users specify `/tmp` as an allowed directory:\r\n1. Server startup resolves `/tmp` to `/private/tmp` and stores only `/private/tmp` in allowedDirectories\r\n2. When user requests `/tmp/file.txt`, the initial validation check fails because `/tmp` doesn't match `/private/tmp`\r\n3. User gets \"Access denied - path outside allowed directories\" error\r\n\r\n**Solution**\r\nStore both the original normalized path andthe resolved path in `allowedDirectories`. This allows users to access files through either form:\r\n- `/tmp/file.txt` matches `/tmp` in allowedDirectories\r\n- `/private/tmp/file.txt` matches `/private/tmp` in allowedDirectories\r\n\r\n## Changes\r\n- `src/filesystem/index.ts`: Modified allowed directory initialization to store both original and resolved paths when they differ\r\n- `src/filesystem/__tests__/path-validation.test.ts`: Added test for the symlink behavior\r\n\r\n## Tests\r\n- [x] Added new test \"allows paths through both original and resolved symlink directories\"\r\n- [x] Verified fix works on macOS by observing both paths in allowedDirectories output\r\n\r\n## Reproduction\r\nBefore fix:\r\n```bash\r\nnpx -y @modelcontextprotocol/server-filesystem /tmp\r\n# Then request /tmp/test.txt -> REJECTED\r\n```\r\n\r\nAfter fix:\r\n```bash\r\nnpx -y @modelcontextprotocol/server-filesystem /tmp\r\n# Server logs: allowed directories: ['/tmp', '/private/tmp']\r\n# Then request /tmp/test.txt -> ACCEPTED\r\n```", "created_at": "2026-01-26T23:29:10Z", "updated_at": "2026-01-26T23:33:31Z", "closed_at": null, "merged_at": null, "merge_commit_sha": "69299ef1d8e1fe88cae3e027abbbab41787b4410",

"## Summary\n\n- Fix \"Resource already registered\" error when calling tools like `gzip-file-as-resource` multiple times with the same output name\n- Track registered resources by URI in a module-level Map\n- Remove existing resource before registering a new one with the same URI\n\n## Problem\n\nWhen a tool that creates session resources (like `gzip-file-as-resource`) is called multiple times with the same output name, the server throws:\n\n```\nError: Resource demo://resource/session/README.md.gz is already registered\n```\n\nThis is particularly problematic because:\n1. The `gzip-file-as-resource` tool has a default name of `README.md.gz`\n2. LLM agents often retry tool calls or call tools multiple times with default parameters\n3. There was no way to update or overwrite an existing resource\n\n## Solution\n\nThe fix tracks registered session resources by URI in a Map, and before registering a new resource, it checks if one already exists with the same URI. If so, it uses the SDK's `remove()` method to unregister the old resource first, then registers the new one.\n\n## Test plan\n\n- [x] Called `gzip-file-as-resource` 10 times with default parameters - all succeed\n- [x] Called with same explicit name multiple times - succeeds\n- [x] Build passes with no TypeScript errors\n- [x] Verified using [Bellwether](https://bellwether.sh) MCP server validation tool\n\n## How this was found\n\nThis bug was discovered using [Bellwether](https://bellwether.sh), an open-source MCP server validation and documentation tool. Bellwether runs automated schema validation and behavioral testing against MCP servers, which caught this regression when repeatedly testing the `gzip-file-as-resource` tool.\n\n🤖 Generated with

"body": "## Summary\n\nThis PR **adds regression test coverage only** for a `directory_tree` structured-content validation bug that appears to have already been fixed upstream.\n\nThere are **no runtime behavior changes** in this PR.\n\n## Context\n\nThe `-32602` error reported in:\n\n- https://github.com/modelcontextprotocol/servers/issues/3106\n- https://github.com/modelcontextprotocol/servers/issues/3093\n\noccurs when a tool declares `outputSchema: { content: string }` but returns `structuredContent.content` as an **array**.\n\nFrom git history, this appears to have been fixed in:\n\n- `e6933ca` — \"Fix: Changed structuredContent output to match outputSchema (#3099)\" (2025-12-11)\n\nNote: I opened this PR after seeing the open bug reports and reproducing the issue in an older build, but I did not initially confirm that `main` already contained the fix. I’m keeping this PR scoped to test coverage in case it’s still useful as a regression guard.\n\n## What this PR does\n\n- Adds `src/filesystem/__tests__/directory-tree.mcp-sdk.test.ts`\n - Uses `@modelcontextprotocol/sdk` + `StdioClientTransport` to call `directory_tree` end-to-end.\n - Asserts that `structuredContent.content` is a `string` and JSON-parseable.\n- Makes `structured-content.test.ts` slightly more robust on macOS by resolving the temp directory with `fs.realpath()` so the allowlist path matches `/private/...` temp paths.\n\nThis is intended to help prevent reintroducing the same outputSchema/structuredContent mismatch.\n\n## Minimal reproduction snippet (for older builds)\n\nI was able to reproduce the `-32602` validation error by running the filesystem server over stdio and calling `directory_tree` through the MCP SDK client.\n\nMaintainers can run the following snippet directly (Node 20+):\n\n```ts\nimport { Client } from '@modelcontextprotocol/sdk/client/index.js';\nimport { StdioClientTransport } from '@modelcontextprotocol/sdk/client/stdio.js';\nimport fs from 'node:fs/promises';\nimport os from 'node:os';\nimport path from 'node:path';\n\nconst tmp = await fs.mkdtemp(path.join(os.tmpdir(), 'mcp-fs-tree-'));\nconst root = await fs.realpath(tmp);\nawait fs.writeFile(path.join(root, 'a.txt'), 'hello');\n\nconst transport = new StdioClientTransport({\n command: 'npx',\n args: ['-y', '@modelcontextprotocol/server-filesystem', root],\n});\n\nconst client = new Client({ name: 'debug-client', version: '1.0.0' }, { capabilities: {} });\nawait client.connect(transport);\n\nconst result = await client.callTool({\n name: 'directory_tree',\n arguments: { path: root },\n});\n\nconsole.log(result.structuredContent);\nawait client.close();\n```\n\nOn buggy builds, this call throws `McpError: -32602 ... Expected string, received array at path: [\"content\"]`.\n\n## Release context\n\nI have not traced the exact release tag for `e6933ca`, but based on timestamps it looks like the fix (2025-12-11) should be included in npm releases published **after that date** (for example `@modelcontextprotocol/server-filesystem@2025.12.18` and later).\n\nHappy to update this PR with the exact release tag if you'd like me to track it down precisely.\n\n## Test plan\n\n- `npm test --workspace @modelcontextprotocol/server-filesystem`\n\n## Follow-up suggestion (optional)\n\nIf you'd like, I can follow up with a small CI-level \"functional\" test job that runs a tiny MCP SDK client against the built `dist/index.js` binaries for select servers (filesystem, memory, etc.) to assert that schema validation passes for a few representative tool calls.\n\nI didn't include CI changes in this PR since I wasn't sure how you'd want to scope cross-package functional tests.\n\n## Authorship note\n\nThis contribution (bug identification, repro, test updates, and PR drafting) was authored with OpenAI Codex.\n", "created_at": "2026-01-24T16:13:10Z", "updated_at": "2026-01-24T16:23:56Z", "closed_at":

The same was true when using symbolic links which involved such characters. \r\n\r\nThe root cause was threefold:\r\n1. Missing UTF-8 encoding initialization for Windows STDIO communication\r\n2. Lack of Unicode normalization (NFC vs NFD forms causing string comparison failures)\r\n3. Inconsistent handling of symlinks pointing to or containing paths with umlauts\r\n\r\nThis PR fixes these issues by:\r\n- Adding UTF-8 encoding initialization for Windows STDIO\r\n- Implementing Unicode NFC normalization in path-utils\r\n- Improving symlink handling with proper encoding support\r\n- Adding better error messages for encoding-related issues\r\n\r\nThe fix benefits all languages with diacritical marks (German, French, Spanish, Nordic, Eastern European, etc.).\r\n\r\n## Publishing Your Server\r\n**Note: We are no longer accepting PRs to add servers to the README.** Instead, please publish your server to the [MCP Server Registry](https://github.com/modelcontextprotocol/registry) to make it discoverable to the MCP ecosystem.\r\n\r\nTo publish your server, follow the [quickstart guide](https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx). You can browse published servers at [https://registry.modelcontextprotocol.io/](https://registry.modelcontextprotocol.io/).\r\n\r\n## Server Details\r\n\r\n- Server: **filesystem**\r\n- Changes to: **Core path handling utilities, validation logic, and initialization**\r\n - `index.ts`: UTF-8 encoding initialization\r\n - `path-utils.ts`: Unicode NFC normalization\r\n - `lib.ts`: Enhanced symlink resolution and error handling\r\n - `roots-utils.ts`: Root URI parsing improvements\r\n\r\n## Motivation and Context\r\n\r\n\r\n### Problem\r\nUsers with non-ASCII characters in their file paths (common in German, French, Spanish, and many other languages) experienced complete filesystem access failures. Specifically:\r\n\r\n1. **Windows users**: Umlauts displayed as `?` due to STDIO encoding mismatch\r\n2. **macOS/Linux users**: Path validation failed because macOS stores filenames in NFD (decomposed Unicode: `ü` = `u` + combining diaeresis) while the server compared against NFC (composed: `ü` = single character)\r\n3. **All platforms**: Symlinks pointing to or containing umlauts failed due to `fs.realpath()` returning inconsistent Unicode forms\r\n\r\n### Real-world Impact\r\nThis made the filesystem server completely unusable for:\r\n- Users with non-English names in their home directory path\r\n- Projects with internationalized directory names\r\n- Any workflow involving symbolic links to such paths\r\n\r\n### Example Failure\r\n```\r\nUser creates: /Users/müller/Projekte\r\nmacOS stores: /Users/mu\\u0308ller/Projekte (NFD)\r\nServer checks: /Users/müller/Projekte (NFC)\r\nResult: \"Access denied\" - string comparison fails\r\n```\r\n\r\nRelated to issue #2098 where Windows users reported umlauts converting to `?`.\r\n\r\n## How Has This Been Tested?\r\n\r\n\r\nTested extensively with **Claude Desktop** on **macOS** with the following scenarios:\r\n\r\n### Test 1: Directory with umlauts\r\n- Created `/tmp/test-bücher/übung.txt`\r\n- `list_directory` correctly shows `übung.txt`\r\n- `read_file` correctly reads content with umlauts\r\n\r\n### Test 2: Symlink with umlaut in name\r\n- Created symlink: `verknüpfung → /target`\r\n- Successfully write files through symlink\r\n- Files appear correctly in target directory\r\n\r\n### Test 3: Symlink to directory with umlauts\r\n- Created symlink: `link → /übungen`\r\n- `list_directory` through symlink works\r\n- `read_file` and `write_file` work through symlink\r\n\r\n### Test 4: Create file with umlaut in name\r\n- Created `neue-übung.txt` with content containing `ÄÖÜ äöü ß`\r\n- File created successfully\r\n- Content preserved correctly\r\n\r\nAll 14 MCP filesystem tools (read, write, list, create, move, search, etc.) now work correctly with umlauts.\r\n\r\n**Testing environment:**\r\n- macOS Sonoma\r\n- Claude Desktop (latest version)\r\n- Node.js v18+\r\n\r\n## Breaking Changes\r\n\r\n\r\n**No breaking changes.** This is a pure bug fix that:\r\n- Maintains backward compatibility with ASCII-only paths\r\n- Requires no configuration changes\r\n- Requires no API changes\r\n- Does not change any existing behavior for paths without umlauts\r\n\r\nUsers can simply update to the new version without any migration steps.\r\n\r\n## Types of changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follow MCP security best practices\r\n- [ ] I have updated the server's README accordingly *(README does not require changes - this is a transparent bug fix)*\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [ ] New and existing tests pass locally *(No existing tests for this functionality; can add unit tests if requested)*\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options *(No new env vars or config options added)*\r\n\r\n## Additional context\r\n\r\n\r\n### Technical Implementation Details\r\n\r\n**Why NFC instead of NFD?**\r\n- NFC (Canonical Composition) is more compact and widely used\r\n- Windows and Linux prefer NFC\r\n- Most databases and APIs expect NFC\r\n- macOS handles both forms transparently\r\n\r\n**Why re-normalize after `fs.realpath()`?**\r\n- `fs.realpath()` resolves symlinks and returns the actual filesystem path\r\n- The filesystem may store paths in a different Unicode form than we normalized earlier\r\n- Critical for symlinks pointing to directories with umlauts\r\n\r\n**Error Handling Improvements:**\r\n- Added detection for `EILSEQ` (illegal byte sequence) and `EINVAL` (invalid argument) error codes\r\n- These indicate encoding issues and now provide helpful error messages\r\n- Helps users identify and report encoding-related problems\r\n\r\n**Performance Impact:**\r\n- `String.normalize('NFC')` adds ~0.01ms per path operation\r\n- Negligible compared to actual filesystem I/O (typically 1-10ms)\r\n- No measurable impact on real-world usage\r\n\r\n**Broader Language Support:**\r\nThis fix benefits all languages using diacritical marks:\r\n- German: ä, ö, ü, ß\r\n- French: é, è, ê, à, ç\r\n- Spanish: ñ, á, í, ó, ú\r\n- Nordic: å, ä, ö, æ, ø\r\n- Eastern European: ł, ż, ś, ć, č, š, ž\r\n- And many more\r\n\r\n### Files Modified\r\n- `src/filesystem/index.ts` (9 lines added - UTF-8 init)\r\n- `src/filesystem/path-utils.ts` (9 lines added - NFC normalization)\r\n- `src/filesystem/lib.ts` (10 lines modified - enhanced error handling)\r\n- `src/filesystem/roots-utils.ts` (8 lines modified - encoding fixes)\r\n\r\nTotal: ~36 lines changed across 4 files - a minimal, focused fix.", "created_at": "2026-01-21T15:51:41Z", "updated_at": "2026-01-23T10:38:35Z", "closed_at": null, "merged_at":

currently limited to pre-configured MCP servers\n- No way to dynamically discover new capabilities\n- No performance/reliability data available\n\n## What MCP Discovery provides\n\n- **Semantic search** using embeddings (24 servers indexed)\n- **Performance metrics** (latency, uptime)\n- **Side-by-side server comparison**\n- **Free hosted API** + self-hosted option\n\n## Tools\n\n| Tool | Description |\n|------|-------------|\n| `discover_mcp_server` | Find servers matching natural language needs |\n| `get_server_metrics` | Get performance data for a server |\n| `compare_servers` | Compare multiple servers side-by-side |\n\n## Example\n\n```\nAgent: \"I need a database with authentication\"\n→ Returns: Supabase MCP (94% confidence) + install command + uptime data\n```\n\n## Links\n\n- **Repo**: https://github.com/yksanjo/mcp-discovery\n- **Live API**: https://mcp-discovery-production.up.railway.app\n- **npm**: https://www.npmjs.com/package/mcp-discovery-api\n\nHappy to

"body": "## Summary\n\nInstead of crashing when a configured directory is unavailable (e.g., unmounted external drive, disconnected network share), the server now skips unavailable directories with a warning and continues operating with the remaining available directories.\n\n## Problem\n\nCurrently, if any directory in `allowed_directories` is unavailable at startup, the entire server crashes with `process.exit(1)`. This makes ALL filesystem access unavailable, even for paths that are accessible.\n\nThis is particularly problematic for:\n- Laptop users with external drives that aren't always connected\n- Users with network shares that may be temporarily unavailable\n- Anyone who wants to configure multiple directories where some might not always be mounted\n\n## Solution\n\nThe server now:\n- Validates each directory individually\n- Skips unavailable directories with a warning log message\n- Continues operating with the remaining available directories\n- Only exits if ALL specified directories are unavailable\n\n### Example log output\n\n```\nWarning: Skipping unavailable directory /Volumes/External-Drive: ENOENT: no such file or directory\nSkipped 1 unavailable directory: /Volumes/External-Drive\nServer starting with 2 available directories: /Users/username/Documents, /Users/username/Desktop\n```\n\n## Testing\n\nTested locally with a mix of available and unavailable directories. The server now starts successfully and operates on the available directories while logging warnings about the unavailable ones.\n\nFixes #2815", "created_at": "2026-01-06T12:57:53Z", "updated_at":

"## Description\r\n\r\nAdd optional `distill` parameter to the fetch server that aggressively cleans HTML content to minimize token usage. When enabled, removes scripts, styles, navigation, headers, footers, ads, and other non-essential elements before conversion to markdown. Achieves **72.8% average token reduction** across real-world tests.\r\n\r\n## Server Details\r\n- Server: fetch\r\n- Changes to: tools (added `distill` parameter to `fetch` tool)\r\n\r\n## Motivation and Context\r\n\r\nLLM token costs are a significant operational expense. Current `web-fetch` returns full HTML including navigation menus, ads, scripts, and UI clutter - wasting tokens on non-content elements.\r\n\r\n**Test Results:**\r\n| Website | Standard Tokens | Distilled Tokens | Reduction |\r\n|---------|-----------------|------------------|-----------|\r\n| MCP Docs | 2,154 | 13 | 99.4% |\r\n| TechCrunch | 506 | 263 | 48.0% |\r\n| Python Docs | 662 | 629 | 5.0% |\r\n| **Average** | 1,107 | 302 | **72.8%** |\r\n\r\n## How Has This Been Tested?\r\n\r\n- Tested with Claude Desktop as MCP client\r\n- Tested against multiple real-world websites (documentation sites, news sites, technical docs)\r\n- Verified backward compatibility - existing calls without `distill` parameter work unchanged\r\n\r\n## Breaking Changes\r\n\r\nNone. The `distill` parameter defaults to `False`, maintaining full backward compatibility.\r\n\r\n## Types of changes\r\n- [ ] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\nNo new dependencies required - uses existing `readabilipy` for content extraction.\r\n",

SSL certificate verification. This allows the fetch server to work with internal servers that use self-signed certificates.\r\n\r\n## Changes\r\n\r\n- Added `SSL_VERIFY` configuration via `MCP_FETCH_SSL_VERIFY` env var (default: `true`)\r\n- Added `verify=SSL_VERIFY` to both `AsyncClient` instances \r\n- Added comprehensive SSL error handling with helpful error messages\r\n- Error messages guide users to set `MCP_FETCH_SSL_VERIFY=false` for self-signed certs\r\n\r\n## Usage\r\n\r\n~~~bash\r\nexport MCP_FETCH_SSL_VERIFY=false\r\n~~~\r\n\r\n> ⚠️ **Security Note:** Disabling SSL verification reduces security.

}, "body": "## Description\r\n\r\nAdds support for SEP-1577 (Sampling With Tools) to the Everything server by introducing a new `trigger-agentic-sampling` tool that demonstrates the agentic sampling loop pattern.\r\n\r\nThis tool:\r\n- Sends a prompt to the client's LLM with tools available\r\n- Handles `tool_use` responses and executes tools locally\r\n- Loops until a final text response is received or max iterations reached\r\n- Only registers if the client supports `sampling.tools` capability\r\n\r\n## Server Details\r\n\r\n- Server: everything\r\n- Changes to: tools\r\n\r\n## Motivation and Context\r\n\r\nIssue: #3040\r\n\r\nSEP-1577 adds tool calling support to the MCP sampling API, enabling servers to provide tools that the LLM can use during sampling requests. This creates an \"agentic loop\" where:\r\n\r\n1. Server sends `sampling/createMessage` with a `tools` array\r\n2. If the LLM returns `stopReason: \"toolUse\"`, the server executes the tools\r\n3. Server sends tool results back and continues until final response\r\n\r\nThe Everything server is a reference implementation that demonstrates all MCP features, so it should include this capability.\r\n\r\n## How Has This Been Tested?\r\n\r\n- Build passes successfully\r\n- Tool registration is conditional on `sampling.tools` capability check\r\n- Follows the same pattern as existing conditional tools (`trigger-sampling-request`, `trigger-elicitation-request`)\r\n- Tested with custom client using local build of Typescript SDK (see also: https://github.com/modelcontextprotocol/typescript-sdk/issues/1346 )\r\n\r\n(We can wait to merge until I've had a chance to add a screengrab if that's preferred.)\r\n\r\n## Breaking Changes\r\n\r\nNo\r\n\r\n## Types of changes\r\n\r\n- [ ] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n### References\r\n- [SEP-1577 Proposal](https://github.com/modelcontextprotocol/modelcontextprotocol/issues/1577)\r\n- [Specification changes](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/1796)\r\n- [TypeScript SDK changes](https://github.com/modelcontextprotocol/typescript-sdk/pull/1101)\r\n- [Inspector support](https://github.com/modelcontextprotocol/inspector/issues/932)\r\n\r\n### Implementation Notes\r\nThe tool includes simple local implementations of `echo` and `add` tools for demonstration purposes. In a production scenario, tools could likely be reused via:\r\n- Internal `server.server.callTool()` calls\r\n- Connecting to other MCP servers as a client\r\n- Shared business logic functions\r\n\r\nI thought about trying to re-use existing tools already defined in the everything server, but then decided to keep it self-contained instead.", "created_at": "2025-12-30T03:59:58Z",

The bug causes:\r\n- Files appearing with ./ prefix (e.g., ./index.md)\r\n- The .git directory itself being staged\r\n- Corrupted commits requiring git filter-repo to fix\r\n\r\n## Motivation and Context\r\n\r\nThe previous implementation only handled the exact case of [\".\"] but failed to handle [\".\", \"other.md\"] or [\"./README.md\"]. This fix uses repo.git.add() (CLI wrapper) for all cases, which is consistent with how other git operations are implemented in this file and correctly handles all edge cases.\r\n\r\n## Testing\r\n\r\nI have been using the `mcp-server-git` MCP to allow Claude to edit a private [otterwiki](https://otterwiki.com). Prior to making this change locally, I was seeing corruption of the Git repository every few commits. Since applying the change about a week ago, I have been using the wiki with Claude every single day and have not seen a single error of any kind.\r\n\r\n## Breaking Changes\r\n\r\nNone\r\n\r\n## Types

"Title\r\nfix(memory): enhance schema compatibility for strict JSON validators (like Gemini CLI)\r\n\r\nDescription\r\nThis PR updates the memory server's Zod schemas to improve compatibility with MCP clients that enforce strict JSON schema validation, such as the Google Gemini CLI. \r\n\r\nThe changes include:\r\n 1. Formally declaring the optional type property in EntitySchema and RelationSchema.\r\n 2. Enabling .passthrough() on these schemas to allow for internal or future properties without breaking strict validation.\r\n\r\nServer Details\r\n - Server: memory\r\n - Changes to: tools (Output schemas for read_graph, search_nodes, and open_nodes)\r\n\r\nMotivation and Context\r\nStrict MCP clients like the Gemini CLI perform rigorous validation on tool outputs. The memory server includes a type field in its internal JSONL storage which is subsequently returned in tool outputs. Since this field was not declared in the tool's output schema, Gemini CLI rejected the response with an \"additional properties not allowed\" error (code -32602).\r\n\r\nBy declaring the type field and using .passthrough(), we ensure the server remains robust and compatible with both permissive and strict clients.\r\n\r\nHow Has This Been Tested?\r\nTested locally using google-gemini-cli:\r\n - Verified that read_graph no longer triggers validation errors and returns the full graph.\r\n - Verified that search_nodes and open_nodes successfully return structured content.\r\n - Confirmed that data remains intact in the memory.jsonl file.\r\n\r\nBreaking Changes\r\n - No. This change is additive and increases tolerance for existing data structures.\r\n\r\nTypes of changes\r\n - [x] Bug fix (non-breaking change which fixes an issue)\r\n - [ ] New feature (non-breaking change which adds functionality)\r\n - [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n - [ ] Documentation update\r\n\r\nChecklist\r\n - [x] I have read the [MCP Protocol Documentation (https://modelcontextprotocol.io)\r\n - [x] My changes follows MCP security best practices\r\n - [x] I have updated the server's README accordingly (N/A - no user-facing config changes)\r\n - [x] I have tested this with an LLM client\r\n - [x] My code follows the repository's style guidelines\r\n - [ ] New and existing tests pass locally (Need to run npm test)\r\n - [x] I have added appropriate error handling\r\n - [x] I have documented all environment variables and configuration options (N/A)\r\n\r\nAdditional context\r\nThe type discriminator is essential for the server's internal logic when parsing the JSONL file. Formalizing its presence in the communication schema resolves the \"hidden property\" conflict with strict validators.\r\n", "created_at": "2025-12-23T04:48:32Z", "updated_at": "2026-01-19T15:24:02Z",

"## Summary\n\nCreates a central `INSTALLATION.md` and updates all server READMEs to reference it, addressing documentation drift concerns raised in #2956.\n\n## Changes\n\n- **New:** `INSTALLATION.md` - Central installation guide covering:\n - Quick reference table for all 7 servers\n - TypeScript (npx) vs Python (uvx/pip) installation patterns\n - Client configurations (Claude Desktop, VS Code, Zed, Zencoder)\n - Docker patterns\n - Debugging with MCP Inspector\n\n- **Updated:** All 7 server READMEs with reference link to central guide:\n - `src/everything/README.md`\n - `src/fetch/README.md`\n - `src/filesystem/README.md`\n - `src/git/README.md`\n - `src/memory/README.md`\n - `src/sequentialthinking/README.md`\n - `src/time/README.md`\n\n## Why This Approach\n\nPer @domdomegg's comment in #2956: standardization prevents documentation drift where some apps have outdated setup steps compared to others.\n\nThis is a \"light touch\" approach that:\n1. Creates a single source of truth for common installation patterns\n2. Keeps server-specific details in their individual READMEs\n3. Minimizes review burden\n4. Can be extended in future PRs for fuller README standardization\n\n## Testing\n\n- [x] Verified all relative links resolve correctly (`../INSTALLATION.md`)\n- [x] Checked markdown renders properly\n- [x] No existing content removed\n\nFixes #3064", "created_at": "2025-12-08T06:56:54Z", "updated_at": "2025-12-08T07:07:11Z", "closed_at": null, "merged_at": null, "merge_commit_sha":

them from relations:\n```json\n{\"type\":\"entity\",\"name\":\"...\",\"entityType\":\"...\",\"observations\":[...]}\n```\n\nBut the output schema only expects `{name, entityType, observations}` - no `type` field.\n\nThis causes all read operations to fail with:\n```\nMCP error -32602: Structured content does not match the tool's output schema: data.entities[0] should NOT have additional properties\n```\n\n## Solution\nStrip the `type` field using destructuring before pushing to result arrays:\n```typescript\nif (item.type === \"entity\") {\n const { type, ...entity } = item;\n graph.entities.push(entity as Entity);\n}\nif (item.type === \"relation\") {\n const { type, ...relation } = item;\n graph.relations.push(relation as Relation);\n}\n```\n\n## Testing\n- All 39 existing tests pass\n- All read operations now return valid responses\n- Write operations continue to work correctly\n- Existing JSONL files remain fully compatible\n\nFixes #3074", "created_at":

default stdio transport.\r\n\r\n## Server Details\r\n\r\n- Servers: memory, sequential-thinking\r\n- Changes to: transport layer (added HTTP support alongside stdio)\r\n\r\n## Motivation and Context\r\n\r\nThis change enables these servers to be used in environments where HTTP transport is preferred or required over stdio, such as web-based clients or containerized deployments. The implementation maintains backward compatibility by defaulting to stdio transport.\r\n\r\n## How Has This Been Tested?\r\n\r\n- Tested stdio transport (default behavior) remains unchanged\r\n- Tested HTTP transport with `MCP_TRANSPORT=http` environment variable\r\n- Verified session management (initialization, message handling, cleanup)\r\n- Confirmed both POST/GET/DELETE request handling works correctly\r\n\r\n## Breaking Changes\r\n\r\nNo breaking changes. This is fully backward compatible:\r\n- Default behavior (stdio) is unchanged\r\n- HTTP transport is opt-in via `MCP_TRANSPORT=http` environment variable\r\n\r\n## Types of changes\r\n\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [x] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\nImplementation follows the pattern from the Immich MCP server PR. Key features:\r\n- Uses `@modelcontextprotocol/sdk` v1.23.0 StreamableHTTPServerTransport\r\n- Session management with UUID-based session IDs\r\n- Supports POST (send), GET (receive), DELETE (close) HTTP methods\r\n- Environment variables:\r\n - `MCP_TRANSPORT=http` - enables HTTP transport (default: stdio)\r\n - `PORT` - HTTP port number (default: 3000)\r\n", "created_at":

errors\r\n\r\n## Description\r\n\r\nSolves the following issue: Bug Report and Resolution: mcp-server-memory Failures due to Race Condition and Environment Misconfiguration #2579\r\n\r\nThe memory server had no protection against concurrent file writes. When multiple operations tried to read, modify, and write to the `memory.jsonl` file simultaneously, they would corrupt the file causing JSON parsing errors. This fix implements a Promise-based in-memory lock manager that serializes all file operations, ensuring atomic read-modify-write cycles without data loss or corruption.\r\n\r\n## Server Details\r\n\r\n- Server: memory\r\n- Changes to: Core file operation logic and locking mechanism\r\n\r\n## Motivation and Context\r\n\r\n\r\nThe memory server was experiencing critical failures when handling concurrent tool invocations:\r\n1. **Race Condition**: Multiple concurrent read-modify-write operations on `memory.jsonl`\r\n2. **File Corruption**: Interleaved writes resulted in truncated JSON lines\r\n3. **Data Loss**: Some writes would completely overwrite others\r\n4. **JSON Parse Errors**: \"Unexpected non-whitespace character after JSON\" when reading corrupted files\r\n\r\nThis was particularly problematic when Claude made multiple memory operations in quick succession or when the server handled rapid concurrent requests. The fix ensures all operations are properly serialized while maintaining high performance through JavaScript's asynchronous Promise-based queue system.\r\n\r\n## How Has This Been Tested?\r\n\r\n\r\nComprehensive testing with vitest including:\r\n- **Race Condition Prevention Tests** (5 tests): Concurrent entity/relation creation, high-concurrency scenarios, mixed read/write operations\r\n- **Lock Verification Tests** (6 tests): Serialization verification, JSONL format integrity, atomic operation verification\r\n- **Existing Tests**: All 30 original knowledge graph tests continue to pass\r\n- **Coverage**: 82.69% statement coverage, 97.46% branch coverage, 94.73% function coverage\r\n\r\nTotal: **50/50 tests passing** with no regressions\r\n\r\n## Breaking Changes\r\n\r\n\r\nNo breaking changes. The fix is transparent to users:\r\n- Same API and tool signatures\r\n- Same file format (JSONL)\r\n- No configuration changes required\r\n- Backward compatible with existing `memory.jsonl` files\r\n\r\n## Types of changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Implementation Details\r\n\r\n### Changes Made\r\n\r\n1. **Lock Manager Implementation** (`src/memory/index.ts`):\r\n - Added `LockManager` class using Promise-based queue for per-file serialization\r\n - All file operations wrapped with `executeWithLock()` to ensure atomicity\r\n - No external dependencies required (removed `proper-lockfile`)\r\n\r\n2. **Test Suite Enhancement**:\r\n - Created `race-condition.test.ts` with 5 comprehensive concurrent access tests\r\n - Created `lock-verification.test.ts` with 6 lock mechanism verification tests\r\n - Both follow vitest standards per CONTRIBUTING.md requirements\r\n - Removed Python test files in favor of TypeScript equivalents\r\n\r\n3. **Dependencies**:\r\n - Removed: `proper-lockfile` and `@types/proper-lockfile`\r\n - Added: None (uses built-in Promise-based async/await)\r\n\r\n### How It Works\r\n\r\nThe `LockManager` maintains a Map of Promise chains, one per file. When an operation is requested:\r\n1. Get the current lock promise for the file (or start with resolved Promise)\r\n2. Chain the new operation to that promise\r\n3. Store the updated promise chain for future operations\r\n4. This ensures operations execute sequentially without data corruption\r\n\r\n### Performance Considerations\r\n\r\n- **No blocking**: Uses JavaScript's asynchronous Promise queue, not OS-level blocking\r\n- **Minimal overhead**: Simple Map lookup and Promise chaining\r\n- **Efficient**: Operations complete faster due to serialization (no partial writes)\r\n- **Scalable**: Works for single instance deployments (intended use case)\r\n\r\n## Additional Context\r\n\r\n\r\n### Architecture Notes\r\n\r\nThe fix assumes a single MCP server instance, which is the standard deployment model for MCP servers. The in-memory Promise-based lock provides optimal performance for this scenario while preventing all race conditions within a single process.\r\n\r\n**⚠️ Important: This is a Temporary Measure for Single Editor Usage**\r\n\r\nThis implementation is designed for users running **one code editor/LLM client at a time** (e.g., Claude Desktop, VS Code, or CLI - but not multiple simultaneously). If you use multiple LLM clients or editors concurrently with the same memory file, you may still experience race conditions.\r\n\r\n### Multi-Client Scenarios\r\n\r\nIf you need to use multiple LLM clients/editors simultaneously (e.g., Claude CLI + Gemini CLI + VS Code all at the same time), you should implement one of the following production-ready locking strategies:\r\n\r\n#### Option 1: SQLite Database (Recommended)\r\n- **Library**: Use `better-sqlite3` or built-in Node.js SQLite support\r\n- **Advantages**: ACID transactions, process-safe, no external dependencies\r\n- **Implementation**: Replace JSONL storage with SQLite tables\r\n- **Example**:\r\n ```typescript\r\n import Database from 'better-sqlite3';\r\n \r\n const db = new Database('memory.db');\r\n // Transactions handle all locking automatically\r\n db.exec('BEGIN TRANSACTION');\r\n // ... read and write operations ...\r\n db.exec('COMMIT');\r\n ```\r\n\r\n#### Option 2: Redis with Atomic Operations\r\n- **Library**: `redis` npm package\r\n- **Advantages**: Distributed locking, multi-machine support, battle-tested\r\n- **Implementation**: Store graph in Redis with Lua scripting for atomic operations\r\n- **Example**:\r\n ```typescript\r\n const client = redis.createClient();\r\n // SET with NX (only if not exists) for locks\r\n const acquired = await client.set('memory:lock', '1', { NX: true, EX: 30 });\r\n ```\r\n\r\n#### Option 3: Filesystem Locks with Retry Logic\r\n- **Library**: `proper-lockfile` (production-ready version) or `fs-ext`\r\n- **Advantages**: No external services required, cross-process safe\r\n- **Implementation**: Use OS-level file locks with exponential backoff\r\n- **Note**: Requires careful error handling and timeout management\r\n\r\n#### Option 4: Message Queue Pattern\r\n- **Library**: Bull, RabbitMQ, or Apache Kafka\r\n- **Advantages**: Serializes all operations globally, scalable\r\n- **Implementation**: Queue all graph operations through a message broker\r\n- **Use Case**: Large-scale systems with many concurrent clients\r\n\r\n### Recommendations by Use Case\r\n\r\n| Use Case | Recommendation | Rationale |\r\n|----------|---|---|\r\n| Single editor (Claude Desktop or VS Code) | Current in-memory locks ✓ | Optimal performance, simple, sufficient |\r\n| Local multi-client (CLI + Desktop) | SQLite with transactions | No external dependencies, ACID guarantees |\r\n| Production deployment | Redis or SQLite | Robust, scalable, battle-tested |\r\n| Enterprise multi-machine | Redis + Lua scripting | Distributed locking support |\r\n\r\n### Future Improvements\r\n\r\nConsider opening an issue or PR to implement:\r\n1. Pluggable lock strategy pattern\r\n2. SQLite backend option as default\r\n3. Configuration to choose lock implementation\r\n4. Documentation on multi-client setups\r\n\r\n### Related Issues\r\n\r\n- Fixes the \"Unexpected non-whitespace character after JSON\" errors reported in issue #2579\r\n- Also prevents similar issues that could occur in the filesystem server or other servers with concurrent file access\r\n\r\n### Testing Recommendations\r\n\r\nWhen integrating with Claude Desktop or other LLM clients:\r\n1. Test rapid consecutive memory operations\r\n2. Test concurrent tool invocations\r\n3. Verify memory persists correctly across sessions\r\n4. Monitor for any JSON parsing errors in logs\r\n\r\nAll tests should pass with the new implementation.\r\n", "created_at": "2025-11-25T10:53:25Z", "updated_at": "2025-11-25T10:57:14Z", "closed_at":

This resulted in a Docker image that appeared to build successfully but was non-functional because the `dist` directory was missing.\r\n\r\nThis fix ensures the TypeScript code is properly compiled by explicitly running `npm run build` after installing dependencies.\r\n\r\n## How Has This Been Tested?\r\n- Built the Docker image using: `docker build -t mcp/sequentialthinking -f src/sequentialthinking/Dockerfile .`\r\n- Tested MCP protocol communication with: `echo '{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"initialize\",\"params\":{\"protocolVersion\":\"2024-11-05\",\"capabilities\":{},\"clientInfo\":{\"name\":\"test\",\"version\":\"1.0\"}}}' | docker run --rm -i mcp/sequentialthinking`\r\n- Verified the server responds correctly to `initialize` and `tools/list` requests\r\n- Tested with Augment Code MCP client configuration\r\n\r\n## Breaking Changes\r\nNo breaking changes. Users with the previous broken Docker image will need to rebuild it, but the configuration remains the same.\r\n\r\n## Types of changes\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n**Before:** The Dockerfile ran `npm ci --ignore-scripts --omit-dev` which prevented the TypeScript compilation.\r\n\r\n**After:** The Dockerfile now explicitly runs `npm run build` to compile TypeScript to JavaScript, ensuring the `dist` directory is created and the Docker image is functional.\r\n\r\nThis fix makes the Docker installation method documented in the README actually work as intended.", "created_at": "2025-11-07T15:39:33Z", "updated_at":

flag)\r\n- Add GitPush model with comprehensive field descriptions\r\n- Register git_push as a new tool in the MCP server\r\n- Add test coverage for push functionality\r\n- Update README with git_push tool documentation\r\nResolves #618\r\n\r\n## Description\r\n\r\nThis PR implements the `git_push` tool for the Git MCP server, enabling users to push branches to remote repositories. This addresses issue #618 where users need the ability to push branches remotely to support integration with other MCPs that create pull requests.\r\n\r\n## Server Details\r\n\r\n- Server: git\r\n- Changes to: tools, README documentation\r\n\r\n## Motivation and Context\r\n\r\nUsers working with multiple MCPs need the ability to push branches to remote repositories before creating pull requests through other tools. The Git MCP server previously lacked this functionality, limiting its utility in CI/CD and automation workflows. This feature enables seamless integration with other MCPs that depend on remote branch existence.\r\n\r\n## How Has This Been Tested?\r\n\r\n- Added `test_git_push_no_remote()` unit test to verify error handling when pushing to a non-existent remote\r\n- Verified syntax and imports compile correctly with Python 3.10\r\n- Tested with actual GitPython library to ensure proper argument composition\r\n\r\n## Breaking Changes\r\n\r\nNo breaking changes. This is a new tool addition that does not affect existing functionality.\r\n\r\n## Types of changes\r\n\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [x] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with unit tests\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all parameters and configuration options\r\n\r\n## Additional context\r\n\r\nThe implementation uses GitPython's `repo.git.push()` method with dynamic argument construction to support:\r\n- Optional branch specification (defaults to current branch)\r\n- Custom remote targets (defaults to 'origin')\r\n- Force push for overwriting remote history\r\n- Upstream tracking with the `-u` flag\r\n\r\nAll parameters are optional with sensible defaults, making the tool flexible for various use cases.\r\n\r\n---\r\n\r\n**Built with

"body": "## Description\r\n\r\nFixes #2807\r\n\r\nAdded two new tools to the filesystem MCP server for enhanced file modification capabilities:\r\n- `append_file`: Appends content to existing files without overwriting\r\n- `write_or_update_file`: Creates new files or appends to existing ones (smart create-or-append)\r\n\r\nThese tools complement the existing `write_file` tool by providing non-destructive file operations, addressing the common use case where users want to add content to files while preserving existing data.\r\n\r\n## Server Details\r\n\r\n- Server: filesystem\r\n- Changes to: tools (added 2 new tools), core library functions, tests\r\n\r\n## Motivation and Context\r\n\r\n\r\nThe existing `write_file` tool always overwrites file content, which is problematic when users want to:\r\n- Add content to existing log files or documents\r\n- Incrementally build up file content\r\n- Preserve existing data while adding new information\r\n\r\nThese new tools solve this by providing:\r\n1. **append_file**: Safe appending to existing files (fails if file doesn't exist)\r\n2. **write_or_update_file**: Flexible create-or-append operation (creates if needed, appends if exists)\r\n\r\n## How Has This Been Tested?\r\n\r\n\r\n- ✅ Tested with MCP client using local build\r\n- ✅ All unit tests pass (51/51)\r\n- ✅ Tested scenarios:\r\n - Appending to existing files\r\n - Creating new files with write_or_update_file\r\n - Appending to existing files with write_or_update_file\r\n - Error handling (file not found, permission errors)\r\n - Atomic write operations with concurrent access\r\n\r\n## Breaking Changes\r\n\r\n\r\nNo breaking changes. These are new tools that don't affect existing functionality.\r\n\r\n## Types of changes\r\n\r\n- [ ] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n\r\n**Implementation details:**\r\n- Both functions use atomic write operations (temp file + rename) for safety\r\n- Follow existing patterns from the codebase for consistency\r\n- Proper error handling and cleanup of temporary files\r\n- Comprehensive test coverage added (6 new test cases)\r\n- Tool descriptions clearly explain use cases and differences\r\n", "created_at": "2025-10-03T15:51:07Z", "updated_at": "2026-02-13T08:35:56Z", "closed_at": null, "merged_at": null, "merge_commit_sha":

"## Description\r\n\r\nAdd `read_graph_summary` function to the memory MCP server for efficient entity overview without loading the entire knowledge graph. This new function provides entity names, types, observation counts, and most recent observations while preserving full relation data, significantly reducing context usage for overview scenarios.\r\n\r\nThis allows LLMs to get an overview of the graph in order to make a better decisions about which entities to fully load into the context with `open_nodes`\r\n\r\n## Server Details\r\n- Server: memory\r\n- Changes to: tools (added new `read_graph_summary` tool)\r\n\r\n## Motivation and Context\r\nThe existing `read_graph` function returns complete entity data including all observations, which can become very large and consume significant context space when users only need an overview of their knowledge graph. This creates inefficiency when:\r\n\r\n- LLMs want to quickly scan what entities exist and their recent activity\r\n- LLM context is being consumed by large observation arrays\r\n- LLMs need to identify entities of interest before diving into full details\r\n\r\nThe `read_graph_summary` function solves this by providing:\r\n- Entity names and types for quick identification\r\n- Observation counts to understand data richness\r\n- Most recent observation for context about latest activity\r\n- All relations preserved for understanding connections\r\n\r\nLLMs can then use the existing `open_nodes` function to get full details for specific entities of interest.\r\n\r\n## How Has This Been Tested?\r\n\r\n**Comprehensive testing completed using VSCode with MCP integration:**\r\n\r\n1. **Functional Testing**:\r\n - Created test entities with varying observation counts (3-24 observations)\r\n - Verified correct entity summary structure (name, entityType, observationCount, lastObservation)\r\n - Confirmed most recent observation is correctly identified and returned\r\n - Tested with empty graph (returns empty arrays)\r\n\r\n2. **Performance Verification**:\r\n - Tested with entity containing 24 observations\r\n - `read_graph`: Returns full 24-observation array\r\n - `read_graph_summary`: Returns count + last observation only\r\n\r\n3. **Integration Testing**:\r\n - Verified tool registration in MCP protocol\r\n - Confirmed proper JSON schema validation\r\n - Tested workflow: `read_graph_summary` → identify entities → `open_nodes` for details\r\n\r\n4. **Edge Case Testing**:\r\n - Empty entities arrays\r\n - Entities with single observations\r\n - Relations-only graphs\r\n\r\n## Breaking Changes\r\n**No breaking changes** - This is a purely additive feature that:\r\n- Adds a new optional tool (`read_graph_summary`)\r\n- Does not modify existing tool behavior\r\n- Maintains backward compatibility\r\n- Requires no configuration changes\r\n\r\n## Types of changes\r\n- [ ] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [x] Documentation update\r\n\r\n## Checklist\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n**Implementation Details:**\r\n- Uses existing `loadGraph()` infrastructure for consistency\r\n- Creates lightweight `EntitySummary` interface separate from full `Entity`\r\n- Preserves all relations unchanged for compatibility\r\n- Returns `KnowledgeGraphSummary` type for clear API contracts\r\n- Follows existing async/await patterns and error handling\r\n\r\n**Performance Benefits:**\r\n- Significant reduction in context usage for overview scenarios\r\n- Enables efficient \"browse then deep-dive\" workflows\r\n- Maintains full functionality through complementary tool usage\r\n- Zero performance impact on existing tools\r\n\r\n**Design Decision:**\r\n- Returns most recent observation rather than first/random to provide most current context\r\n- Includes observation count to help users understand data richness\r\n- Keeps relations unchanged to maintain graph connectivity information\r\n- Uses separate interface to clearly

mixing glob and substring matching\n- Updated tests to reflect the new consistent glob-only behavior\n\n## Changes\n- Modified pattern matching in `buildTree` to use only minimatch glob patterns\n- Updated search_files to accept array of patterns instead of single pattern for better flexibility\n- Adjusted test cases to use proper glob patterns (e.g., `**/node_modules` for nested directories)\n- Improved tool descriptions in the API to be clearer about glob pattern usage\n\nFixes #896", "created_at": "2025-08-23T06:51:21Z", "updated_at": "2025-09-29T11:52:29Z", "closed_at": null, "merged_at":

graceful path validation. The server now logs warnings for problematic paths at startup but continues running, allowing operations to retry at runtime when storage becomes available.\r\n\r\n## Server Details\r\n\r\n- Server: filesystem\r\n- Changes to: startup validation logic, path handling, error handling, logging\r\n\r\n## Motivation and Context\r\n\r\n\r\nAddresses GitHub issues #2113 and #2483. The filesystem server would crash immediately if any configured directory path was invalid, inaccessible, or pointed to a file instead of a directory. This was problematic for users with:\r\n\r\n- Network Attached Storage (NAS) that might be temporarily offline\r\n- VPN-mounted drives that connect after server startup \r\n- USB/external drives that may not be connected at startup\r\n- Typos in path configuration\r\n- Directories that don't exist yet but will be created later\r\n\r\nThe original behavior provided a poor user experience and made the server fragile in dynamic storage environments.\r\n\r\n## How Has This Been Tested?\r\n\r\n\r\n- [x] Tested with valid accessible directories (normal operation)\r\n- [x] Tested with non-existent paths (graceful warning, runtime retry)\r\n- [x] Tested with file paths instead of directories (proper skipping)\r\n- [x] Tested with mixed valid/invalid configurations\r\n- [x] Verified parallel validation performance with Promise.all\r\n- [x] Confirmed runtime operations work when storage becomes available\r\n\r\n## Breaking Changes\r\n\r\n\r\nNo breaking changes. This is backwards compatible - existing configurations continue to work. The only change is that invalid paths now generate warnings instead of crashes.\r\n\r\n## Types of changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality) \r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [ ] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [ ] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n\r\n**Implementation Details:**\r\n- Replaced sequential validation loop with `Promise.all` for better performance\r\n- Added clear comments explaining retry vs skip logic for different path types\r\n- Regular files are permanently excluded (can never become directories)\r\n- Symlinks and special files are included for runtime retry (NAS/VPN scenarios)\r\n- Inaccessible paths are included for runtime retry (network storage, permissions)\r\n\r\n**Design Philosophy:**\r\nThe new approach is optimistic about dynamic storage - we include paths that might become valid directories later while permanently excluding things that can never be directories. This balances robustness with usability for modern storage environments.", "created_at": "2025-08-22T19:13:07Z", "updated_at": "2025-08-24T02:31:14Z", "closed_at": null, "merged_at": null,

encoding.\r\n\r\n## Description\r\n\r\nThis PR adds a new tool, `get_file_hash`, to the **filesystem** MCP server.\r\n\r\n- Computes cryptographic digests via Node `crypto.createHash` + streaming\r\n `fs.createReadStream` (efficient on large files)\r\n- Supported algorithms (policy gate): `md5`, `sha1`, `sha256` (default: `sha256`)\r\n- Output encoding: `\"hex\"` (default) or `\"base64\"` (optional)\r\n- Rejects non-regular files (directories/devices); respects roots/realpath checks\r\n- Zod input schema + `ListTools` registration\r\n- README updated with a tool entry consistent with existing docs\r\n\r\n## Server Details\r\n- Server: **filesystem**\r\n- Changes to: **tools** (new tool), **unit tests** (new tests), **docs** (README tools section)\r\n\r\n## Motivation and Context\r\n\r\nI’m a computer forensics expert; verifying file integrity is critical to chain of\r\ncustody. Standards (e.g., ISO/IEC 27037, SWGDE) emphasize hashing digital evidence.\r\nNIST recommends collision-resistant hashes (SHA-2); SHA-1/MD5 remain for legacy\r\nidentification but not for collision-sensitive uses. This tool defaults to SHA-256\r\nwhile retaining MD5/SHA-1 for interoperability. Keeping the algorithm set small\r\nimproves DFIR compatibility and simplifies model prompts.\r\n\r\nProviding `get_file_hash` inside the filesystem server lets LLM-driven workflows\r\ncompute/compare hashes under the same allowed-roots and realpath/symlink controls\r\nas other file operations—no external copying, consistent and auditable results.\r\n\r\n## How Has This Been Tested?\r\n\r\n- **Environment:** macOS 15.5, LM Studio 0.3.22\r\n- **MCP client:** LM Studio (server built via Docker and used as a Docker-mapped\r\n MCP server; tool discovered via `ListTools`)\r\n- **Models:**\r\n - qwen/qwen3-coder-30b (benefits from explicit “when to use” + args in prompt)\r\n - openai/gpt-oss-120b (works with concise descriptions)\r\n - mistralai/devstral-small-2507 (tool calls succeed)\r\n- **Unit tests:** text vectors (`\"abc\"`, `\"ForensicShark\"`), small binary snippet,\r\n encodings (hex/base64), non-regular paths rejected (dir/symlink/device), and\r\n unsupported algorithms (e.g., `sha512`, `crc32`, `whirlpool`) rejected by policy\r\n- **Manual:** end-to-end via stdio within LM Studio; expected digests returned;\r\n clear error on unavailable algorithms (FIPS/build)\r\n- **Platform note:** Not tested on Windows\r\n\r\n## Breaking Changes\r\nNone. Additive only.\r\n\r\n## Types of changes\r\n- [x] New feature (non-breaking)\r\n- [x] Documentation update\r\n- [ ] Bug fix\r\n- [ ] Breaking change\r\n\r\n## Checklist\r\n- [x] Follows MCP security best practices (roots-restricted, realpath/symlink checks)\r\n- [x] README updated (tool entry)\r\n- [x] Code follows repo style guidelines\r\n- [x] Appropriate error handling (unsupported algorithms / non-regular files)\r\n- [x] Inputs documented (path, algorithm, encoding)\r\n- [x] Tested with an LLM client (LM Studio)\r\n- [x] New and existing tests pass locally\r\n- [ ] CI not included in this PR (out of scope)\r\n\r\n## Additional context\r\n- Paths should be **relative to the allowed base directory** (as returned by\r\n `list_directory`) when calling the tool from clients.\r\n- Tool description made concise and Qwen-friendly; instructs models to return\r\n only the digest string.\r\n- Only `md5`, `sha1`, `sha256` are supported by design; no extended algorithms\r\n or env toggles in this PR.\r\n", "created_at": "2025-08-09T14:32:51Z", "updated_at": "2025-08-13T12:58:37Z", "closed_at": null, "merged_at": null, "merge_commit_sha": null, "assignee": null, "assignees": {},

and private label limiting access to only the current container on bind mount files (Z) referenced by Dockerfile RUN. This allows the container to be used with a podman and SELinux configuration. Without it, the build fails due to the security system (SELinux) blocking attempts to use bind mounted content /app/pyproject.toml (and eventually /app/uv.lock).\r\n\r\n**Resources:**\r\n- [https://developers.redhat.com/articles/2025/04/11/my-advice-selinux-container-labeling](https://developers.redhat.com/articles/2025/04/11/my-advice-selinux-container-labeling#2__run_container_with_a_private_volume_)\r\n- https://cheatsheetseries.owasp.org/cheatsheets/Docker_Security_Cheat_Sheet.html#rule-6-use-linux-security-module-seccomp-apparmor-or-selinux\r\n- https://docs.docker.com/engine/storage/bind-mounts/#configure-the-selinux-label\r\n\r\n## Server Details\r\n- Server: fetch, git, time\r\n- Changes to: Dockerfile\r\n\r\n## Motivation and Context\r\nIt improves compatibility / accessibility and enables security enhancements for hardened container environments.\r\n\r\nUltimately, the motivation is to allow using MCP servers with docker / podman on hosts that have [SELinux container separation enabled and enforcing](https://developers.redhat.com/articles/2025/04/11/my-advice-selinux-container-labeling) (default for podman). See also: [rule 6 from OWASP security cheat sheet](https://cheatsheetseries.owasp.org/cheatsheets/Docker_Security_Cheat_Sheet.html#rule-6-use-linux-security-module-seccomp-apparmor-or-selinux).\r\n\r\nAdditionally, one of the base images does not have the user / group “app” currently which is being used with a `--chown` that fails. This is secondary to the purpose of this PR, but `app:app` may need to exist in order for the build step to succeed in a fresh environment.\r\n\r\n## How Has This Been Tested?\r\nDocker / Podman build on the Dockerfile in question. Then the built images were run as integrations for a customized LLM client / frontend.\r\n\r\nUnder src/fetch directory\r\n`podman build -t mcp/fetch .`\r\n\r\nUnder src/time directory\r\n`podman build -t mcp/time .`\r\n\r\nUnder src/git directory\r\n`podman build -t mcp/git .`\r\n\r\nThe container build commands now succeed for docker / podman with security systems that are configured to handle containers.\r\n\r\n## Breaking Changes\r\nNo known / identified breaking changes.\r\n\r\n## Types of changes\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\nLLM client test done with [mcpo](https://github.com/open-webui/mcpo) Dockerfile that is setup to include the artifacts from the built mcp/time. Then this was included as a full OpenAPI spec in tools for the local LLM client in use (see screenshot for end result).\r\n![IMG_1081](https://github.com/user-attachments/assets/228bd28f-ac87-45d8-9a13-91158f924e67)\r\n\r\nFor the missing user/group scenario, consider approach from [DoD’s iron bank container for python312](https://repo1.dso.mil/dsop/opensource/python/python312/-/blob/development/Dockerfile?ref_type=heads#L72-73) which (at the time of writing this) explicitly creates a group / user with

read_file_lines:\r\n1. Basic functionality:\r\n - [x] Various offsets and limits\r\n2. Security boundaries:\r\n - [x] Only works in allowed dir\r\n3.

"\r\n\r\nTitle:\r\nfix: Unicode normalization for macOS screenshot files and Unicode filenames\r\n\r\n\r\n\r\n## Summary\r\n\r\n- All file operations now normalize Unicode in file paths (NFC, non-breaking space, special Unicode punctuation)\r\n- Fixes ENOENT errors for macOS screenshot files and similar Unicode edge cases\r\n- Adds excellent comments explaining rationale and edge cases\r\n- Documents change and test results in README and PR_TEST_RESULTS.md\r\n- All tests (create, move, read, list) pass for both normal and non-breaking space filenames\r\n- See PR_TEST_RESULTS.md for full test evidence.\r\n\r\n## Description\r\nSee PR_TEST_RESULTS.md for full test evidence.\r\n### Unicode Normalization for File Operations\r\nAdded a [sanitizeFilePath](https://musical-disco-q7wjww6rr6rf6x5g.github.dev/) utility in [index.ts](https://musical-disco-q7wjww6rr6rf6x5g.github.dev/) that:\r\nNormalizes all file paths to Unicode NFC form.\r\nReplaces non-breaking spaces (U+00A0) with regular spaces.\r\nReplaces a range of special Unicode spaces and punctuation that can appear in macOS screenshot filenames and other OS-generated files.\r\nIntegrated this normalization into all file operations by calling [sanitizeFilePath](https://musical-disco-q7wjww6rr6rf6x5g.github.dev/) in the [validatePath](https://musical-disco-q7wjww6rr6rf6x5g.github.dev/) function, ensuring every file operation (move, read, etc.) is robust against Unicode edge cases.\r\n\r\n## Server Details\r\n\r\nServer: filesystem\r\n\r\nChanges to:\r\n\r\n1. Core file path handling logic (Unicode normalization in all file operations)\r\n2. Documentation (README.md, new PR_TEST_RESULTS.md)\r\n3. Code comments (improved clarity and rationale in index.ts)\r\n\r\n## Motivation and Context\r\nManual drag-and-drop in Finder\r\nRename files to simpler names first\r\nUse Terminal with shell globbing: mv Screenshot*.png ./Images/\r\n\r\n## How Has This Been Tested?\r\nTest results attached in results.md. tested with Claude and Gemini\r\n\r\n## Breaking Changes\r\nNo\r\n\r\n## Types of changes\r\n\r\n- [ x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ x] Documentation update\r\n\r\n## Checklist\r\n\r\n- [ x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [ x] My changes follows MCP security best practices\r\n- [ x] I have updated the server's README accordingly\r\n- [x ] I have tested this with an LLM client\r\n- [x ] My code follows the repository's style guidelines\r\n- [ x] New and existing tests pass locally\r\n- [x ] I have added appropriate error handling\r\n- [x ] I have documented all environment variables and configuration options\r\n\r\n##

[issue #1869](https://github.com/modelcontextprotocol/servers/issues/1869) by adding a flexible mechanism to prevent accidental overwrites of sensitive files (such as `.env`) in the Filesystem MCP server.\r\n\r\nSummary of changes:\r\n- Added a `--ignore-write ...` command-line argument to the filesystem server.\r\n- The server now blocks write operations to any file matching the provided patterns (supports globs like `.env`, `.env.*`, `*.secret`, etc.), even if the file is within an allowed directory.\r\n- Updated the README.md to document the new option and provide usage examples.\r\n- Improved security and user control over which files are protected from write operations.\r\n\r\nMotivation:\r\nPreviously, the server could overwrite sensitive files (e.g., `.env`) without confirmation, risking data loss. This change allows users to specify which files should never be overwritten, improving safety and flexibility.\r\n\r\nTesting:\r\n- Manually tested with various ignore patterns and confirmed that write operations to matching files are blocked with an appropriate error.\r\n- Verified that normal write operations to non-matching files still succeed.\r\n\r\nDocumentation:\r\n- Updated README.md with usage instructions and security notes for the new `--ignore-write` option.\r\n\r\nChecklist:\r\n- [x] Thoroughly tested changes\r\n- [x] Documentation updated\r\n- [x] Linked to issue #1869\r\n-

Details\r\n- Server: filesystem\r\n- Changes to: command-line argument handling, path processing\r\n\r\n## Motivation and Context\r\nThe filesystem server was incorrectly interpreting paths with hyphens as command-line options, leading to errors when users tried to access directories or files with hyphens in their paths. This fix ensures that hyphenated paths are handled correctly.\r\n\r\n## How Has This Been Tested?\r\n- Tested with directories containing hyphens in their paths (e.g., \"sum-delme\")\r\n- Verified directory listing works correctly with hyphenated paths\r\n- Created test files to confirm proper path handling\r\n- Verified Docker deployment works with hyphenated paths\r\n\r\n## Breaking Changes\r\nNone. This is a backward-compatible bug fix that improves handling of paths with hyphens.\r\n\r\n## Types of changes\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [ ] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [ ] Documentation update\r\n\r\n## Checklist\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly (no changes needed as API remains the same)\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options (no changes needed)\r\n\r\n## Additional context\r\nThe fix implements a more robust approach to command-line argument parsing by:\r\n1. Filtering out arguments starting with '-' since they would be interpreted as flags\r\n2. Improving path normalization using Node.js native path functions\r\n3. Enhancing type safety with better TypeScript annotations\r\n\r\nThis ensures that paths with hyphens are correctly processed without affecting other functionality.", "created_at":

"site_admin": false }, "body": "## Description\r\n\r\n1. Fix #896: \"Search file by name\" enhancements\r\n 1. Rename the existing `search_files` function to `search_files_by_name`\r\n 2. Improve performance for deeply nested directories by processing directories in parallel batches.\r\n 3. Improve description to make it clear it's a file/directory name matcher, not a file content search.\r\n 4. Improve error handling\r\n2. Add new `search_file_contents` to search file content.\r\n 1. Plain text or regex pattern matching\r\n 2. Case-sensitive/insensitive search\r\n 3. Configurable result limits\r\n 4. Context lines around matches\r\n 5. File glob filtering (include/exclude)\r\n3. Better parameter documentation throughout\r\n4. Fix #735, #1067: sometimes the LLM was confused what is the exact syntax for file name matching. Is it substring match, regex match, glob pattern or something else? It wasn't very clear from the name and description. \r\n\r\n## Server Details\r\n\r\n- Server: filesystem\r\n- Changes to: tools\r\n\r\n## Motivation and Context\r\n\r\nBoth Claude and human users may misinterpret the `search_files` function as a content search tool (like grep) rather than a file/directory name matcher. The suggested description makes the distinction clear from the beginning and explicitly notes that it doesn't search file contents.\r\n\r\n## How Has This Been Tested?\r\n\r\nTested with Claude Desktop with the following prompts, before and after the change.\r\n1. The \"Before\" column shows which function was selected by the LLM before this PR.\r\n8. The \"After\" column shows which function was selected by the LLM with this PR, for the exact same prompt.\r\n\r\n| Prompt | Before | After |\r\n| --- | --- | --- |\r\n| Find all references to \"XYZ\" under
/Users/my_userid/my_project/ | search_files | search_file_content |\r\n| Find files whose names contain \"color\" under
/Users/my_userid/my_project/ | search_files | search_files_by_name |\r\n| Search files that contain \"XYZ\" under
/Users/my_userid/my_project using filesystem MCP. | search_files | search_file_content |\r\n| Search \"XYZ\" under
/Users/my_userid/my_project using filesystem MCP. | search_files | search_file_content |\r\n| Search \"xyz\" in file a/b/c/foo.cpp | search_files | search_file_content |\r\n\r\nFor prompt 1, the LLM can easily infer it should be searching for file contents, not matching file names. Previously, the LLM mistakenly invoked the `search_files` function, which typically would return no matching results.\r\n\r\nFor prompts 3 and 4, there is intentionally some prompt ambiguity to test how the LLM decide whether to use `search_files_by_name` or `search_file_content` based on the function names and descriptions.\r\n\r\n## Breaking Changes\r\n\r\n> Will users need to update their MCP client configurations?\r\n\r\nNo, but I'm not sure I understand breaking changes. I'm unclear whether it's ok to rename a function, or if it's considered to be a breaking change.\r\n\r\n## Types of changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (non-breaking change which adds functionality)\r\n- [ ] Breaking change (fix or feature that would cause existing functionality to change)\r\n- [x] Documentation update\r\n\r\n## Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follows MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested this with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [ ] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n## Additional context\r\n\r\n### Tests for the `search_file_contents` function\r\n\r\n- [x] Basic text search returns correct results for common terms\r\n- [x] Case-sensitive search correctly differentiates between uppercase and lowercase patterns\r\n- [x] Regex pattern search correctly identifies patterns like function declarations `async function \\w+\\(`\r\n- [x] Context lines display works correctly with different values (0, 2, 4 lines)\r\n- [x] Max results parameter properly limits the number of results returned\r\n- [x] File extension filtering correctly includes only the specified file types (.ts, .js, etc.)\r\n- [x] File extension filtering handles files without extensions correctly\r\n- [x] Exclude patterns with wildcards (`**/*.test.ts`) correctly filter out matching files\r\n- [x] Exclude patterns with simple strings (`*config*`) correctly filter content containing those strings\r\n- [x] Combined search with regex + case sensitivity + file types works correctly\r\n- [x] Search handles large files efficiently without excessive memory usage\r\n- [x] Directory recursion works correctly for nested file structures\r\n- [x] Error handling for inaccessible files or directories works as expected\r\n- [x] Race conditions are avoided when searching directories in parallel\r\n- [x] Files with non-UTF8 encoding are handled gracefully without crashing\r\n", "created_at": "2025-03-17T21:08:02Z", "updated_at": "2025-08-26T18:19:07Z", "closed_at": null, "merged_at":

Improvements\r\n\r\n1. **Enhanced Path Security** (`server.py`)\r\n - **New `PathValidator` Class:** \r\n - Blocks access to system directories (e.g. `/etc`, `/usr`, etc.) \r\n - Prevents path traversal (rejects paths containing `..`) \r\n - Resolves symlinks and validates that paths are within safe roots \r\n - Supports resolving both absolute and relative paths, ensuring that when a base directory (via `--repository`) is configured, all paths are contained within it\r\n\r\n - **Dual-Mode Validation:** \r\n - **Configured Mode:** \r\n - When a valid Git repository is directly configured, tool calls automatically use the base repository and ignore any provided `repo_path` \r\n - When a parent directory is configured, every tool call must include an explicit `repo_path` that is validated against the base directory \r\n - **Unconfigured Mode:** \r\n - The server restricts repository paths to pre-approved safe roots\r\n```mermaid\r\ngraph TD\r\n A[Client Request] --> B{--repository flag provided?}\r\n B -- Yes --> C[Configured Base Directory Provided]\r\n B -- No --> D[Require Explicit repo_path in Tool Call]\r\n\r\n C --> E{Is Configured Base a Git Repo?}\r\n E -- Yes --> F[Automatically use Base Repository]\r\n E -- No --> D\r\n\r\n D --> G[Validate Provided repo_path]\r\n G --> H{repo_path within Allowed Base?}\r\n H -- Yes --> I[Proceed with Operation]\r\n H -- No --> J[Reject Request with Error]\r\n```\r\n\r\n2. **Server Initialization Improvements** (`__init__.py`)\r\n - Removed the forced Git repository check during startup to support parent directories\r\n - Enhanced signal handling (SIGINT, SIGTERM) and graceful cleanup using an explicit event loop\r\n\r\n3. **Tool Access Control & Error Handling** (`server.py`)\r\n - Each tool call now:\r\n - Validates the repository path using the new `PathValidator` \r\n - Resolves relative paths against the configured base directory \r\n - Provides clear, actionable error messages if the path is out-of-scope or invalid\r\n - Tools such as `git_status`, `git_diff`, `git_create_branch`, etc., dynamically adjust their input schema based on the current configuration mode\r\n\r\n4. **Documentation Updates** (`README.md`)\r\n - Added a dedicated \"Repository Path Security\" section describing:\r\n - How operations are restricted to the configured repository (or subdirectories, if using a parent directory)\r\n - The enforcement of safe path practices (blocking `../` traversal, system directory protection)\r\n - Updated tool input details (e.g. renaming `start_point` to `base_branch` in branch creation)\r\n\r\n5. **Enhanced Testing** (`test_server.py`)\r\n - New tests assert that:\r\n - Paths outside the allowed scope are correctly rejected\r\n - The server properly resolves a configured repository or a child repository when a parent directory is used\r\n - Git operations (branch creation, checkout, diff) succeed when given valid paths, and fail gracefully when not\r\n\r\n### Motivation and Context\r\n\r\nThis change is necessary to ensure that the Git MCP server is not vulnerable to malicious path traversal or unintended access to critical system directories. In addition to improving security:\r\n- **Input Validation:** Only paths within the allowed boundaries are permitted.\r\n- **Flexibility:** By introducing parent directory support, the server can now manage multiple repositories safely.\r\n- **Robust Logging:** Enhanced error reporting allows users and administrators to diagnose issues more easily.\r\n\r\n### How Has This Been Tested?\r\n\r\n1. **Unit Tests**\r\n - Extensive tests in `test_server.py` covering safe/unsafe path checks, repository validation, and tool operations\r\n2. **Integration Tests**\r\n - Verified both single-repository mode and parent directory mode using UVX and LLM client calls\r\n - Tested against known system directories to ensure they are appropriately blocked\r\n3. **Security Tests**\r\n - Confirmed that symlink resolution, relative-path prevention, and overall boundary enforcement work as expected\r\n\r\n### Breaking Changes\r\n\r\n- **Configuration Update (Parent Directory Mode):**\r\n - When the `--repository` flag points to a parent directory (instead of a single Git repository), clients must provide an explicit `repo_path` with each tool call.\r\n - Existing configurations assuming a single repository might require adaptation.\r\n\r\n### Types of Changes\r\n\r\n- [x] Bug fix (non-breaking change which fixes an issue)\r\n- [x] New feature (adds functionality for multi-repository support)\r\n- [ ] Breaking change (may require configuration update for parent directory mode)\r\n- [x] Documentation update\r\n\r\n### Checklist\r\n\r\n- [x] I have read the [MCP Protocol Documentation](https://modelcontextprotocol.io)\r\n- [x] My changes follow MCP security best practices\r\n- [x] I have updated the server's README accordingly\r\n- [x] I have tested these changes with an LLM client\r\n- [x] My code follows the repository's style guidelines\r\n- [x] New and existing tests pass locally\r\n- [x] I have added appropriate error handling\r\n- [x] I have documented all environment variables and configuration options\r\n\r\n### Additional Context\r\n\r\n- **Defense-in-Depth Approach:**\r\n 1. Path normalization and resolution \r\n 2. System directory deny list \r\n 3. Symlink protection \r\n 4. Dual-mode containment checks \r\n 5. Copy-on-write argument handling\r\n\r\n- **Tool Dispatch Adjustments:** \r\n Adjusts the schema and parameters on the fly based on whether the base directory is a single repository or a parent directory containing multiple repositories.\r\n\r\n- **Security Impact:** \r\n This PR significantly improves the server's security posture by ensuring:\r\n 1. Unauthorized repository access is prevented.\r\n 2. System directories are blocked.\r\n 3. Symlink vulnerabilities are reduced.\r\n 4. Repository integrity is maintained through strict path validation.\r\n\r\nResolves [#604](https://github.com/modelcontextprotocol/servers/issues/604)", "created_at": "2025-02-15T23:33:55Z",
