Jmap Mcp

A solid JMAP implementation that connects Claude to modern email servers like FastMail, Cyrus IMAP, and Stalwart. You get the full email toolkit: search with filters, send and reply, move messages between folders, mark as read/flagged, and handle threads. The incremental sync tools let you poll for changes efficiently using state tokens. Built on the jmap-jam client library with proper TypeScript types and Zod validation. Most useful when you need programmatic email access that goes beyond basic IMAP, especially for building email automation workflows or integrating with JMAP-compliant providers.
