Frequently asked questions

What is the difference between the remote and local server?

The remote server is hosted by Resend at `mcp.resend.com/mcp`, requires no installation, and uses OAuth. The local server runs via `npx` and uses your Resend API key directly.

How do I authenticate with the server?

For the remote server, use OAuth or pass a Resend API key as a Bearer token via an `Authorization` header. For the local server in stdio mode, set the `RESEND_API_KEY` environment variable.

What are the runtime requirements?

The local server requires Node.js and npx (no additional dependencies). It can be run directly with `npx -y resend-mcp`.

Where do I get an API key and verify a domain?

Create a Resend API key at https://resend.com/api-keys. Verify a sender domain at https://resend.com/domains to send emails.

What transports does the local server support?

The local server supports two transport modes: stdio (default) and HTTP (Streamable HTTP). The remote server uses Streamable HTTP only.
