Exposes your entire Thunderbird mailbox to Claude via 12 MCP tools covering read, search, compose, reply, attachment handling, and folder operations. The architecture is clever: credentials stay in Thunderbird, a background bridge daemon proxies WebExtension API calls, and the MCP layer surfaces them as AI-friendly tools. Everything defaults to safe behavior (replies save as drafts, deletes require confirmation). Tested at scale with 22 accounts and 249,000 messages. Ships with a companion Claude Skill that teaches token-efficient field selection and trust-metadata checks. If you already trust Thunderbird with your email and want Claude to handle triage, search, or draft responses without re-configuring IMAP anywhere, this is the tool.
