TraceHub-MCP: One MCP Toolset to Query Traces Across Jaeger, Datadog, Sentry and More
Ok_Bell443 · reddit · 2026-09-14
- A developer released TraceHub-MCP (v0.4.0), an open-source project offering one unified set of MCP tools for querying traces across five backends: Jaeger, Tempo/Grafana Cloud, Traceloop, Datadog and Sentry, aimed at debugging LLM/GenAI apps.
- It lets an agent pull OTel traces straight into context instead of alt-tabbing between dashboards; it leans on genai. semantic conventions so span queries surface model calls, token counts and tool-call spans as structured data the agent can reason over.
- Forked from traceloop/opentelemetry-mcp-server (Apache-2.0, disclosed attribution), it adds Datadog/Sentry backends, a generic filter layer so tool calls need no backend-specific params, and hardened CI/supply chain: SHA-pinned Actions, bandit, pip-audit, Trivy, Codecov, branch protection, CodeRabbit.
- Installable via pip/uvx, listed on the official MCP registry and Glama, with a GHCR image available.
