From the repository

Clone the repository, configure SMTP credentials (e.g., Gmail app password) in Application.java, build with mvn clean package, then run with --stdio, --sse, or --streamable-http flags. For Claude Desktop, add the server configuration to the client’s config.json. Test via MCP Inspector, REST API (POST /api/test-email, GET /api/health), or direct MCP client calls.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.
