How is data accessed?

All queries go directly against the Prometheus HTTP API; no data is stored locally by the server.

What transport protocols are supported?

stdio (default), HTTP, and SSE (deprecated). HTTP is recommended for web integrations.

What credentials does it need?

It reads `AUTH_TOKEN` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
