概览

What is MCP Prometheus Server?

A production-ready Model Context Protocol (MCP) server implementation in Haskell that provides Claude Desktop with access to Prometheus metrics and queries. It offers five tools for querying, discovering, and exploring Prometheus metrics, built with strict exception handling and thread-safe patterns.

How to use MCP Prometheus Server?

Install using the pre-built binary, build from source with GHC 9.12+ and Cabal, or run via Docker. Configure Claude Desktop by adding an entry in claude_desktop_config.json pointing to the server binary with the --prometheus-url argument pointing to your Prometheus instance.

BSD 3-Clause open source license

Use cases of MCP Prometheus Server

Ask Claude "What's the current CPU usage?" using instant PromQL queries
Visualize memory usage trends over the last hour with range queries
Discover available metric names in your Prometheus instance
Find time series matching specific label selectors
Explore all label names used across metrics for filtering

常见问题

What dependencies are required to build from source?

GHC 9.12+ and Cabal 3.0+ are required; GHCup is recommended for installation.

How do I configure the Prometheus server URL?

Set the `PROMETHEUS_URL` environment variable or use the `--prometheus-url` command-line option (default: `http://your-prometheus-server:9090`).

What should I do if the Docker container exits immediately?

The MCP server expects stdio interaction; use the `-it` flags when running the container.

Can I connect to a Prometheus server on a different network with Docker?

Yes, ensure both containers are on the same Docker network by using `--network` flags.

Is the server compatible with JSON-RPC notifications?

Yes, it properly handles notifications without returning responses per the JSON-RPC specification.
