Overview

The Resend MCP Server facilitates deep integration between your AI agents and the Resend email platform. Users can perform actions such as sending emails, managing contact lists, overseeing broadcasts, and configuring domains by issuing commands from compatible MCP clients like Claude, Cursor, and Claude Code. The server is available in both a hosted remote format and a local package. The remote version simplifies setup by removing the need for local process management, relying on OAuth for secure authentication in browser-based AI environments, while the local TypeScript implementation offers more granular control for self-hosted configurations.

Our verdict

With a security score of 45/100, this project carries a high risk level. Key concerns include the fact that the project is not officially maintained by the vendor and its OAuth and read-only support mechanisms have not yet undergone an editorial security review. It is best suited for developers comfortable managing third-party tools that handle sensitive email communications.

Supports both remote hosted and local deployment modes
Small dependency footprint with only six direct packages
Active development with commits within the last day
Twenty-four contributors reduce single-point-of-failure risks

Community-maintained rather than official vendor software
Lacks editorial verification of security implementation
No homepage link provided in repository metadata

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.
