SigNoz MCP servers: which one to use

Use SigNoz's own MCP server. The community ones offer about 9 query tools each, or a general SDK.

SigNoz makes an MCP server itself, and it is the one to use. SigNoz Cloud users connect to a hosted address for their region, and self-hosted users run the server program on their own machine. Both sign in with a SigNoz service account API key, and the official server can also create and update dashboards and alert rules, and delete notification channels. Create that key from a service account with only the access you want the assistant to have.

Good for

  • SigNoz Cloud users who want Claude or Cursor to search logs and traces
  • On-call engineers who want to ask about alerts and error rates in plain English
  • Self-hosted SigNoz teams who prefer a local server
  • Developers building their own tooling on the SigNoz API

Which SigNoz MCP server to use

Use the official SigNoz server: it is hosted for SigNoz Cloud and also runs on your own machine. Pick DrDroid's server for a small Python query tool, or the hoyasumii server if you want the whole SigNoz API behind a few tools.

Questions

Is there an official SigNoz MCP server?

Yes. SigNoz publishes SigNoz/signoz-mcp-server and documents it on its own docs site, with a hosted version for SigNoz Cloud.

What is the SigNoz Cloud MCP server URL?

It is https://mcp.<region>.signoz.cloud/mcp, with your region in place of <region>. Using the wrong region makes sign-in fail, so find yours under Settings, then Ingestion in SigNoz.

How do I sign in to the SigNoz MCP server?

You enter your SigNoz instance URL and a service account API key. SigNoz's docs say the MCP server checks them and then issues its own tokens for later requests.

Does the SigNoz MCP server work with self-hosted SigNoz?

Yes. The README has a self-hosted install where you run the server program yourself and point it at your SigNoz URL with an API key.

Can the SigNoz MCP server change or delete things?

Yes. Its tool list includes creating and editing dashboards, alert rules, and deleting notification channels. Use a service account with a limited role if you only want the assistant to read.

Does it work in Claude?

Yes. SigNoz's docs show adding SigNoz Cloud as a custom connector in Claude Desktop, and a claude mcp add command for Claude Code.

How is the official server different from DrDroid's and Calmo's?

DrDroid's and Calmo's READMEs each list 9 tools, mostly for fetching dashboards, services and APM metrics, plus ClickHouse and builder queries. The official server's README also lists tools to create and update dashboards and to delete notification channels.

What is the hoyasumii SigNoz server?

It is an unofficial TypeScript SDK for the SigNoz REST API with an MCP server and a CLI. Its README says it covers 241 of 241 API operations for SigNoz v0.142.1.

Are the SigNoz MCP servers free?

The server programs are free and open source: the official one is Apache-2.0 and hoyasumii's is MIT. You still need a SigNoz instance to connect to.
