I build and maintain fastmail-mcp, an open-source Model Context Protocol (MCP) server that lets AI assistants like Claude interact with Fastmail — managing email, contacts, and calendars through 38+ tools.

This project bridges the gap between AI and everyday productivity by giving assistants secure, structured access to your Fastmail account via the JMAP and CalDAV protocols. Features include advanced email search, bulk operations, threading, attachments, contact management, and calendar support.

Your sponsorship helps me dedicate time to maintaining and improving this project and future projects— adding new features, keeping up with protocol changes, responding to issues, and building more MCP integrations for the tools people rely on.

Thank you for supporting open-source development!
