# Using with Claude Desktop It’s recommended to use the Docker image when running the MCP server for Claude Desktop. ::: tip Reference Follow the official instructions to locate/modify your Claude Desktop configuration: - https://modelcontextprotocol.io/quickstart/user#for-claude-desktop-users ::: Edit your `claude_desktop_config.json` to add an entry like one of the following. ## Option A: Run via Docker (recommended) No credentials required on Prometheus (local instance): ```json { "mcpServers": { "prometheus": { "command": "docker", "args": [ "run", "--rm", "-i", "prometheus-mcp:latest" ] } } } ``` With host Prometheus and metrics exporter on port 9091 (macOS/Windows): ```json { "mcpServers": { "prometheus": { "command": "docker", "args": [ "run", "--rm", "-i", "-p", "9091:9091", "prometheus-mcp:latest", "--mcp", "--prometheus-url", "http://host.docker.internal:9090", "--metrics-exporter", "--metrics-port", "9091" ] } } } ``` With Basic Auth (provide env vars): ```json { "mcpServers": { "prometheus": { "command": "docker", "args": [ "run", "--rm", "-i", "-e", "PROMETHEUS_URL=https://prom.example.com", "-e", "PROMETHEUS_USERNAME=api", "-e", "PROMETHEUS_PASSWORD=secret", "prometheus-mcp:latest", "--mcp" ] } } } ``` Linux: to access the host Prometheus without publishing ports, add `--network host` (works only on Linux): ```json { "mcpServers": { "prometheus": { "command": "docker", "args": [ "run", "--rm", "-i", "--network", "host", "prometheus-mcp:latest", "--mcp", "--prometheus-url", "http://localhost:9090" ] } } } ``` ## Option B: Run the local binary If you built or installed the binary locally: ```json { "mcpServers": { "prometheus": { "command": "prometheus-mcp", "args": [ "--mcp", "--prometheus-url", "http://localhost:9090" ] } } } ``` ::: warning Secrets Prefer environment variables (or a host secret manager) over placing credentials directly in `claude_desktop_config.json`. :::
