What the publisher says

From the Jaeger repository's README, as published. We do not edit it. Read it on GitHub

jaeger-mcp

<!-- mcp-name: io.github.mshegolev/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:

  • Speaks the standard Model Context Protocol over stdio — works with Claude Desktop, Claude Code, Cursor, and any MCP client.
  • Is read-only: all 15 tools carry readOnlyHint: true — zero risk of modifying trace data.
  • Returns dual-channel output: structured JSON (structuredContent) for programmatic use + Markdown (content) for human-readable display.
  • Has actionable error messages that name the exact env var to fix and suggest a next step.
  • Supports Bearer token, HTTP Basic auth, or no auth (common for internal deployments).
  • Includes OpenAPI specification documenting the underlying Jaeger Query API (openapi.yaml).
