It exposes three tools:\n\n| Tool | Description |\n|------|-------------|\n| `fetch_langfuse_traces` | Fetch a filtered, paginated list of traces |\n| `get_langfuse_trace_detail` | Fetch full detail for a single trace (including observations, scores) |\n| `list_langfuse_trace_filters` | Show available filter fields and usage examples |\n\n## Installation\n\n### From PyPI (Recommended)\n\n```bash\npip install langfuse-traces-mcp\n```\n\n### From Source\n\n```bash\n# Clone the repository\ngit clone https://github.com/yourusername/langfuse-traces-mcp.git\ncd langfuse-traces-mcp\n\n# Install in development mode (includes test dependencies)\npip install -e \".[dev]\"\n```\n\n## Prerequisites\n\n- **Python 3.10+**\n- **VS Code** with Gemini Code Assist extension (Agent Mode enabled)\n- **Langfuse instance** — cloud ([cloud.langfuse.com](https://cloud.langfuse.com)) or self-hosted\n\n## VS Code Setup\n\n1. Install the package: `pip install langfuse-traces-mcp`\n\n2. Add the MCP server configuration to your VS Code settings. Open VS Code settings (Ctrl/Cmd + ,) and search for \"Gemini Code Assist\". In the settings JSON, add:\n\n```json\n{\n  \"mcpServers\": {\n    \"langfuse-traces\": {\n      \"command\": \"langfuse-traces-mcp\"\n    }\n  }\n}\n```\n\n3. **Reload VS Code** after configuration.\n4. Open Gemini Code Assist chat and **toggle Agent Mode ON**.\n5. The `langfuse-traces` tools should now be available.\n\n## Usage\n\nOnce configured, you can ask your coding agent questions like:\n\n- \"Show me traces from production in the last hour\"\n- \"Get details for trace ID abc-123-xyz\"\n- \"List traces with errors tagged as 'critical'\"\n- \"Show me traces from user 'john.doe' in the staging e…","publisher":{"name":"KD","url":null},"homepage":"https://github.com/KarandeepSinghSodhi/Skill-to-fetch-traces","repository":"https://github.com/KarandeepSinghSodhi/Skill-to-fetch-traces/blob/main/CHANGELOG.md","version":"0.1.3","license":null,"protocols":["mcp"],"tags":["langfuse","mcp","observability","traces","vscode"],"pricing":null,"endpoints":[{"url":"pypi:langfuse-traces-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"dev.version-control","name":"Version Control","confidence":1,"provenance":"derived"},{"slug":"dev.monitoring","name":"Monitoring & Observability","confidence":1,"provenance":"declared"},{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":1,"provenance":"derived"}],"categories":["dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"langfuse-traces-mcp","registry":"pypi","observedAt":"2026-11-03T10:25:23.454Z","publishedAt":"2026-04-23T21:12:42.984828Z","latestVersion":"0.1.3"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"langfuse-traces-mcp","url":"https://pypi.org/project/langfuse-traces-mcp/","firstSeenAt":"2026-09-09T23:25:00.046Z","fetchedAt":"2026-11-03T10:24:44.276Z","normalizedAt":"2026-11-03T10:24:44.276Z"}]},"firstSeenAt":"2026-09-09T23:25:00.046Z","updatedAt":"2026-11-03T10:25:23.454Z"}
