Overview

This server integrates the Resend platform directly into MCP-compatible clients such as Claude, Cursor, and Windsurf. It provides tools to interact with your email ecosystem, including sending messages, managing contacts, broadcasting, and domain administration.

Our verdict

This server holds a high risk level with a security score of 45/100, primarily due to the fact that its OAuth and read-only mode implementations have not yet been editorially reviewed. It is suitable for users comfortable handling API-based integrations but should be approached with caution in highly sensitive environments until security auditing is more robust.

  • Supports both remote HTTP and local execution modes
  • Small footprint with only six direct dependencies
  • Active development with commits within the last three days
  • Security implementation remains unverified by editorial review
  • Missing official homepage link for secondary verification

Setup

Claude Desktop
{
  "mcpServers": {
    "resend-mcp": {
      "args": [
        "-y",
        "resend-mcp"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

  • No read-only mode — running this grants full read/write access.
  • No built-in authentication — anyone with access to this config can invoke every tool it exposes.
