Provides a Node.js-based Model Context Protocol server for sending and reading email through standard SMTP and IMAP protocols.

The Email MCP Server is a versatile Node.js application that transforms standard email protocols (SMTP for sending, IMAP for reading) into a unified Model Context Protocol (MCP) interface. It acts as a middleware, allowing developers to easily integrate email functionality into their applications. Designed to be provider-agnostic, it can connect to any SMTP and IMAP server, with explicit support and configuration guidance for ProtonMail via its Proton Bridge. Clients interact with the server using Server-Sent Events (SSE) for real-time updates and POST requests for sending MCP messages, making it suitable for building dynamic email-aware applications.
