Intro

SigNoz MCP Server connects MCP clients to your SigNoz instance: query traces/logs, inspect alerts, and automate observability workflows using an API key.

Best for: On-call engineers who want agents to triage incidents from traces and logs

Works with: SigNoz instance + API key, stdio MCP clients, Go binary or Docker

Setup time: 6-18 minutes

Key facts (verified)

  • GitHub: 92 stars · 31 forks · pushed 2026-05-13.
  • License: Apache-2.0 · owner avatar + repo URL verified via GitHub API.
  • README-verified entrypoint: go install github.com/SigNoz/signoz-mcp-server/cmd/server@latest.

Main

  • Start with self-hosted stdio mode if you already run SigNoz: add the binary to your MCP client config and pass SIGNOZ_URL + SIGNOZ_API_KEY as env.

  • Use Docker HTTP mode when you want a fixed port and simpler deployment; README provides a docker run example with TRANSPORT_MODE=http.

  • Version-pin SigNoz APIs: README notes SigNoz v0.120.0+ is required for some alert rule tools (v2 rules APIs).

Source-backed notes

  • README says only Admin users can create API keys in SigNoz (Settings → API Keys).
  • README includes go install ...@latest and a rename step to get a signoz-mcp-server binary on PATH.
  • README documents stdio MCP config with SIGNOZ_URL and SIGNOZ_API_KEY env vars, plus Docker HTTP mode examples.

FAQ

  • Do I need SigNoz Cloud?: No — README describes connecting to self-hosted instances via URL + API key.
  • What’s the safest first run?: Use read-only query tools first and confirm API key scope before automations that mutate alerts.
  • How do I deploy it without Go?: README offers release binaries and Docker images in addition to go install.
