{
  "mcpServers": {
    "grafana": {
      "type": "stdio",
      "command": "bunx",
      "args": ["@daanrongen/grafana-mcp"],
      "env": {
        "GRAFANA_URL": "http://localhost:3000",
        "GRAFANA_API_KEY": "your-service-account-token"
      }
    }
  }
}

Claude Code CLI

claude mcp add grafana \
  -e GRAFANA_URL=http://localhost:3000 \
  -e GRAFANA_API_KEY=your-service-account-token \
  -- bunx @daanrongen/grafana-mcp

Development

bun install
bun run dev        # run with --watch
bun test           # run test suite
bun run typecheck  # type-check with tsc
bun run lint       # biome lint
bun run format     # biome format
bun run build      # bundle to dist/main.js

Inspecting locally

Use the MCP Inspector to browse and call tools interactively against a real Grafana instance:

GRAFANA_URL=http://localhost:3000 \
GRAFANA_API_KEY=your-service-account-token \
bun run inspect

This opens the MCP Inspector UI in the browser, pointed at the locally built server.
