Gmail MCP Server

# MCP Gmail Server A minimal Model Context Protocol (MCP) server that sends emails through Gmail. ## Quick Start 1. Install dependencies: ```bash npm install ``` 2. Set up Gmail credentials: ```bash cp .env.example .env # Edit .env with your Gmail credentials ``` 3. Build and run: ```bash npm run build npm start ``` ## Configuration Set these environment variables in `.env`: - `GMAIL_USER`: Your Gmail address - `GMAIL_PASS`: Gmail App Password (not your regular password) ## Usage The server exposes one tool: `send_email` **Parameters:** - `to`: Recipient email address - `subject`: Email subject line - `body`: Email content (plain text) ## Files - `src/index.ts` - Main MCP server implementation - `.well-known/mcp.json` - MCP server manifest - `.vscode/mcp.json` - VS Code MCP configuration ## Testing ```bash # Test with MCP Inspector npx @modelcontextprotocol/inspector node build/index.js ## How It Works 1. Creates MCP server with Gmail transporter 2. Registers `send_email` tool with input validation 3. Connects via STDIO transport for MCP communication 4. Returns structured responses with success/error states
