Resend MCP Server

An MCP server for Resend — connect any MCP-compatible client to the Resend transactional email API.

What is this?

An MCP (Model Context Protocol) server that gives AI assistants and agents full access to Resend's email API — send single or batch emails, manage sending domains, API keys, audiences, and contacts — through natural language.

Use it with Claude Desktop, Cursor, Windsurf, Cline, Continue, or any MCP-compatible client to send emails, manage infrastructure, and build automation around email.

Why use this?

• 18 built-in tools — covers sending (single + batch), domains, API keys, audiences, and contacts
• Send emails by talking — "send a welcome email to jane@example.com" just works
• Manage your infrastructure — create/verify/delete domains, mint/revoke API keys, manage contacts
• Batch sending — send up to 100 emails in a single API call
• Full contact CRUD — create, read, update, and delete contacts across audiences
• Rate-limited automatically — respects Resend's 10 req/s free tier, retries on 429
• Works with every MCP client — Claude Desktop, Cursor, Windsurf, Cline, Continue, and more

Quick Start

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "resend": {
      "command": "npx",
      "args": ["-y", "resend-mcp-server"],
      "env": {
        "RESEND_API_KEY": "re_xxxxxxxxxxxx"
      }
    }
  }
}
