FAQ from Email sending MCP 💌

How do I authenticate with the remote server?

The remote server uses OAuth via a browser login. For headless clients, pass a Resend API key as a Bearer token in the Authorization header.

Can I run the server locally instead of using Resend’s hosted version?

Yes. Install resend-mcp via npx and configure it with your API key. It supports both stdio and HTTP transport modes.

What transport modes are available for the local server?

Stdio (default) and HTTP (Streamable HTTP). Use --http and --port flags to run the HTTP server on a custom port.

Do I need a verified domain to send emails?

Yes, you must verify a domain in Resend. You can also use the default [email protected] sender for testing.

What happens if I don’t set a default sender email address?

The server will ask for the sender email each time you call the send tool. You can set a default using SENDER_EMAIL_ADDRESS or the --sender option.
