## Description

JMAP-MCP is a connector that enables AI assistants to read and search emails through the JMAP (JSON Mail Access Protocol) standard, specifically designed for integration with Fastmail servers. Built by Jahfer Husain, the implementation provides three core tools: retrieving mailbox lists, searching emails with extensive filtering options including date ranges, keywords, attachments, and full-text search, and fetching complete email content including text and HTML bodies. The server handles complex email operations like thread collapsing, cross-mailbox searches, and blob content downloading, making it valuable for users who want conversational access to their email data without manual inbox management or complex JMAP API interactions.
