Credentials

Resend API keyapi_key$ resend login

Acquired by the CLI — running resend login opens the auth flow and stores the credential.

OAuth 2.0oauth2

OAuth 2.0 — self-onboarding

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
