What is Prometheus MCP Server?

A Go-based MCP server that integrates with Prometheus, currently supporting only SSE transport mode. It is for users who want to interact with Prometheus metrics through the Model Context Protocol.

How to use Prometheus MCP Server?

Run the Docker container with environment variables for your Prometheus URL and optional authentication (basic auth or Bearer Token), then configure your MCP client (e.g., Cursor Desktop) with the SSE URL shown in the container logs. The server can be toggled to stdio mode by changing MCP_SERVER_TRANSPORT.

Does Prometheus MCP Server require Docker to run?

Yes, the primary deployment method is through Docker. The README provides a Docker run command and instructions for building the image yourself.

Can I build the server image myself?

Yes, you can clone the repository and run docker build -t prometheus-mcp-server . to create a custom image.

Where do I find the SSE URL to configure in my MCP client?

After starting the container, run docker logs prometheus-mcp-server to see the URL (e.g., http://10.0.0.1:8000/sse).
