The MCP server itself is open source and free to run. You need a Resend account, which has a free tier; sending volume beyond it is billed by Resend.

Does it support remote/OAuth?

The default is local stdio with a RESEND_API_KEY. It can also run over HTTP for remote integrations, where each client passes its Resend API key as a bearer token in the Authorization header. There is no OAuth flow.

Run npx -y resend-mcp with RESEND_API_KEY set, or use claude mcp add resend -e RESEND_API_KEY=re_xxx -- npx -y resend-mcp for Claude Code.

Resend MCP server

OfficialResend522Config last verified Jun 1, 2026

Resend's official MCP server lets agents send, schedule, and manage email plus contacts, broadcasts, and domains.

Resend MCP is Resend's official server for sending and managing email from any MCP client. The agent can send a single transactional email or batch send to many recipients, with full support for HTML and plain text, attachments by local path, URL, or base64, CC/BCC, reply-to, scheduling in natural language, and tags. Beyond sending it manages the full Resend surface: inbound received emails and their attachments, contacts and segment and topic memberships, broadcast campaigns, reusable templates with a live visual editor, sender domains, audience segments, subscription topics, custom contact properties, automations, events, logs, API keys, and webhooks.

The canonical setup is stdio over npx (npx -y resend-mcp) with a RESEND_API_KEY environment variable, which is the simplest way to wire it into Claude Desktop, Cursor, or Claude Code. It can also run over HTTP for remote or web-based integrations, in which case each client authenticates by passing its Resend API key as a bearer token in the Authorization header. An optional default sender and reply-to address can be supplied so the agent does not have to ask each time.

What you can do with it

Send and schedule transactional email

An agent drafts and sends a one-off email, or schedules it with natural language like 'tomorrow at 10am', then checks delivery status with get-email.

Run a broadcast campaign

The agent creates a broadcast, composes it in the visual editor, and sends it to an audience, then manages contacts, segments, and topics around it.
