Content
Resend MCP Server
A Model Context Protocol (MCP) server implementation for the Resend email
service.
Features
- Send emails using Resend through a standardized MCP interface
- TypeScript support
Prerequisites
- A Resend API key (get one at resend.com)
- Node.js 18 or later
Installation
- Clone the repository
- Install dependencies:
npm install
Configuration
Create a .env file in the root directory with your Resend API key:
RESEND_API_KEY=your_api_key_here PORT=3000 # Optional, defaults to 3000
Development Status
The server implementation is currently blocked by TypeScript type issues with
the MCP SDK. The following issues need to be resolved:
- The
Serverclass from@modelcontextprotocol/sdkis not properly exposing
its request handling methods in the TypeScript types. - The exact method name for handling requests needs to be determined (tried:
handleRequest,handle,receiveMessage,receive,processRequest).
Next Steps
- Check the MCP SDK documentation or source code for the correct method name
- Update the TypeScript types in the SDK if they are incorrect
- Consider using JavaScript temporarily until the types are fixed
Usage
