Resend's official MCP server: send and read email, manage contacts, broadcasts, domains and webhooks from your agent
Install
claude mcp add --transport http resend https://mcp.resend.com/mcpRemote server; complete OAuth via /mcp after adding.
This is third-party code. Review the repository files before installing.
What it does
The server exposes nearly the whole Resend platform to the agent. It can send email with attachments, scheduling and tags, read inbound mail, and manage templates, contacts, segments and subscription topics. It handles broadcasts and automations, sender domains, the suppression list, API keys and webhooks, and can inspect API request logs. It runs as a remote server hosted by Resend with OAuth, or locally as an npm package.
Who it is for. For developers and marketers who send transactional email and newsletters through Resend.
Good fit when
- You need to send an email or test broadcast straight from the agent
- You need to set up a domain, template or webhook without the dashboard
- You need to debug a failed delivery through logs and events
Not a fit when
- You do not send email through Resend
- You want bulk sending without human review
Example request
Send a test email to my address through Resend using the welcome templateLimitations
Requires a Resend account and a verified sender domain. The local server needs an API key, the remote one uses OAuth. Without a default sender address the server asks for one on every send.
How to disable. Run claude mcp remove resend or delete the entry from the client config, then revoke the API key in the Resend dashboard.

FAQ
Remote or local server?
The remote one is hosted by Resend, needs no install and uses OAuth. The local one runs via npx with an API key over stdio or HTTP.
How do I connect without a browser?
Pass your Resend API key as a Bearer token in the Authorization header.
