This project provides a simple Message-Centric Processing (MCP) server for sending emails directly from AI chat applications like Cursor and Claude Desktop. It allows users to leverage AI models for composing emails and then send them without manual copy-pasting, streamlining workflows for tasks like sending script results or team updates.

How It Works

The MCP server is built using Node.js and integrates with the Resend API for email delivery. It acts as a bridge, translating commands from the AI chat application into API calls to Resend. This approach enables direct email sending capabilities within the chat interface, supporting plain text and HTML emails, scheduling, CC/BCC recipients, and customizable sender/reply-to addresses.

Quick Start & Requirements

• Install: Clone the repository, run npm install, and npm run build.
• Prerequisites: Node.js, a Resend account with an API key, and a verified domain for sending emails to other addresses.
• Setup: Configure the MCP server within Cursor or Claude Desktop settings by providing the absolute path to the build/index.js script and your Resend API key.
• Docs: Resend Email Sending Docs

Highlighted Details

Limitations & Caveats

The project requires local building and manual configuration within the host application. Sending emails to addresses other than your own requires domain verification with Resend. The README does not mention any specific limitations regarding email volume or sending frequency.
