Nitrosend MCP Server

Optional stdio bridge for Nitrosend. Most clients should connect directly to Nitrosend's remote MCP server at https://api.nitrosend.com/mcp; this package exists for stdio-only clients and local development.

People connecting email tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
