Install Resend in Claude Code, Cursor or VS Code

Runs npx -y @supernova123/resend-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

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. claudedesktopconfig.json):

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

Get a free API key at resend.com/api-keys.

Use it

Ask your AI assistant things like:

  • "Send an email to jane@example.com thanking her for signing up"
  • "List the last 5 emails I sent"
  • "What happened to email ID abc-123?"
  • "Create a new sending domain for mail.acme.com"
  • "Verify domain domain-xyz"
  • "Mint a new API key called 'production-server'"
  • "Add jane@example.com to audience audience-1"
