Jaeger Mcp
Connects Claude to your Jaeger distributed tracing backend via the standard Query API. Exposes five read-only tools: list services and operations, search traces with filters (time range, tags, duration), fetch full trace details with span trees, and map service dependencies. Returns both JSON and Markdown for each query, so you can ask "show me 500 errors in order-service from the last hour" or "what called postgres most often this week" and get actionable answers. Supports Bearer tokens, HTTP Basic auth, or no auth for internal deployments. Useful when you're debugging production incidents in chat and need to pull trace data without context switching to the Jaeger UI.

Readme
jaeger-mcp
MCP server for Jaeger distributed tracing. Give Claude (or any MCP-capable agent) read access to your trace data — search traces, inspect spans, compare traces, compute span statistics, map service dependencies, predict performance issues, and forecast capacity needs — without leaving the conversation.
Why another Jaeger MCP?
The existing Jaeger integrations require a running UI or custom scripts. This server:
