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

- Transport
- stdio, http
- Authentication

Environment variables
RESEND_API_KEYrequired, secret- Resend API key, required for local stdio mode
SENDER_EMAIL_ADDRESS- Default sender address on a verified domain
REPLY_TO_EMAIL_ADDRESSES- Comma-separated reply-to addresses
MCP_PORT- Port for HTTP mode
Limitations
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.
