Overview

What is prometheus-mcp-server?

A Golang-based Model Context Protocol (MCP) server that enables natural language interactions with Prometheus metrics and queries. It acts as a bridge between MCP-compatible clients (like Claude Desktop) and Prometheus servers, providing full compatibility with the Prometheus HTTP API v1.

How to use prometheus-mcp-server?

Run the server by specifying the Prometheus address and transport. Use Docker, a pre-built binary, or build from source. Example: prometheus-mcp-server --prom-addr="http://localhost:9090" (defaults to stdio transport). Configurable flags: -prom-addr, -transport (stdio, http, sse), -mcp-addr.
