JMAP Email MCP MCP Server

This MCP server enables seamless interaction with the JMAP modern email protocol, providing developers and applications with a robust interface for email communication. Built in TypeScript, it delivers contemporary email functionality that moves beyond traditional SMTP and IMAP limitations, offering standardized, efficient access to email systems. The server acts as a bridge between client applications and JMAP-compliant email servers, simplifying integration of advanced email capabilities into any development project.

The server supports comprehensive email operations including message retrieval, composition, sending, and management across multiple mailboxes and accounts. It handles full JMAP protocol specifications with features such as push notifications, real-time synchronization, and efficient bandwidth usage through batched requests. Users can perform sophisticated filtering, sorting, and searching operations while maintaining full control over email organization and metadata. The implementation provides reliable error handling and supports modern authentication mechanisms required by contemporary email infrastructure.

Compatible with any client application capable of communicating with MCP servers, this solution serves developers building email clients, productivity tools, and communication platforms. Organizations implementing JMAP-based email systems can leverage this server to accelerate development cycles and reduce integration complexity. Typical use cases include building custom email applications, automating email workflows, developing multi-account email managers, and creating specialized communication tools that require direct protocol-level email access. The community-driven approach ensures continuous improvement and broad compatibility across diverse email environments.
