概要

What is Email sending MCP 💌?

The Email sending MCP 💌 server connects AI agents to the Resend platform, enabling them to send and receive emails, manage contacts, broadcasts, domains, and more. It works with any MCP client like Claude, Cursor, or Claude Code and is offered both as a remote hosted server and a local npm package.

How to use Email sending MCP 💌?

Use the remote server at https://mcp.resend.com/mcp with OAuth login, or install the local server via npx -y resend-mcp with a Resend API key (set RESEND_API_KEY environment variable). The local server supports stdio (default) and HTTP transport modes. For web‑based clients, simply add the remote URL as a custom connector.

よくある質問

1

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.

2

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.

3

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.

4

Do I need a verified domain to send emails?

Yes, you must verify a domain in Resend. You can also use the default `onboarding@resend.dev` sender for testing.

5

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.
