Add to Claude Code

Already added MetricDuck in claude.ai? Claude Code signed in with that Claude account (a claude.ai subscription login, not an API key) already has it: /mcp lists it as claude.ai MetricDuck. Skip the commands below; adding the server here replaces that connector in Claude Code.

claude mcp add --transport http -s user metricduck https://mcp.metricduck.com/mcp
claude mcp login metricduck

The login step opens your browser once for one-click sign-in (Google or GitHub); your account is created on first use. Over SSH, add --no-browser. For headless agents, use an API key as a Bearer token.

ChatGPT: add MetricDuck in ChatGPT. Claude: add it from Claude’s connector directory. Cursor, VS Code and other clients: the setup guide (Claude Code steps).
