Returns a `session_id` to use in subsequent calls. |\n| `langobs_report_trace` | Report a trace event (LLM call, tool call, decision, memory op, error). |\n| `langobs_report_memory` | Report a memory state change (created, updated, accessed, deleted). |\n\n## How It Works\n\nThe MCP server receives tool calls from your agent and forwards them to the LangObs HTTP server (`http://localhost:8766`). Events appear in the dashboard in real-time.\n\n```\nAgent → MCP call → langobs-mcp server → HTTP POST → LangObs server → Dashboard\n```\n\n## Example Usage (inside a Claude conversation)\n\nOnce the MCP server is connected, Claude can instrument its own tasks:\n\n```\n1. Call langobs_start_session → get session_id\n2. For each tool call: langobs_report_trace(session_id, event_type=\"tool_call\", ...)\n3. For each LLM decision: langobs_report_trace(session_id, event_type=\"decision\", ...)\n```\n\nOpen `http://localhost:5173` to watch the trace build in real time.\n\n## License\n\nMIT","publisher":{"name":"LangObs Contributors","url":null},"homepage":"https://github.com/langobs/langobs#readme","repository":"https://github.com/langobs/langobs/issues","version":"0.2.0","license":"MIT","protocols":["mcp"],"tags":["agents","ai","debugging","llm","mcp","model-context-protocol","observability"],"pricing":null,"endpoints":[{"url":"pypi:langobs-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"code.debugging","name":"Debugging","confidence":1,"provenance":"declared"},{"slug":"dev.monitoring","name":"Monitoring & Observability","confidence":1,"provenance":"declared"},{"slug":"analytics.reporting","name":"Reporting & Dashboards","confidence":0.814,"provenance":"derived"}],"categories":["analytics","code","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":"langobs-mcp","registry":"pypi","observedAt":"2026-10-28T08:28:14.955Z","publishedAt":"2026-07-07T22:12:03.114206Z","latestVersion":"0.2.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"langobs-mcp","url":"https://pypi.org/project/langobs-mcp/","firstSeenAt":"2026-09-09T23:25:00.783Z","fetchedAt":"2026-10-28T08:27:24.132Z","normalizedAt":"2026-10-28T08:27:24.132Z"}]},"firstSeenAt":"2026-09-09T23:25:00.783Z","updatedAt":"2026-10-28T08:28:14.955Z"}
