An open-source project for a local iCloud Mail MCP integration. Currently provides only contribution and quality foundations, with Apple Mail access and MCP features deferred.

Enables AI agents to search and page through local Thunderbird mbox mail, read message bodies and attachments with SHA-256 verification, open native compose windows, create native drafts, and send explicitly authorized email through existing Thunderbird identities over MCP stdio. Queries stay read-only and never modify the mbox, while account authentication and real delivery remain with Thunderbird.

Lets an AI assistant save drafts and open compose windows for sending mail in Thunderbird or Betterbird, with optional account listing for sender selection. It deliberately exposes no ability to read, search, move, delete, forward or reply to mail, and has no contact, calendar, folder or filter access.
