Why this exists

Most AI mail connectors live in the cloud and only work with Gmail or Outlook. If your mail lives in Apple Mail — a self-hosted IMAP server, iCloud, a company account — there was no clean way to give an assistant access.

This MCP server talks to the apps on your Mac directly. That means:

• Any MCP client. Desktop chat apps, local-model apps, coding agents — anything that can start an MCP server over stdio.
• Any account Apple Mail can open works. Self-hosted, iCloud, Exchange, Gmail-via-IMAP — if it's in Mail.app, your assistant can see it.
• Nothing to install. No Node, no Python, no Homebrew. It runs on JavaScript for Automation, which ships with every Mac.
• Your mail stays on your Mac. The server has no network code. The assistant only sees what it asks for; where that goes next depends on your model (a local model keeps everything on the Mac).
• Two permission prompts, not thirty. Everything is grouped into a read tool and a write tool. Approve read once and forget about it.
• Works with small local models too. Arguments are forgiving ("true", "3 days ago", folder instead of mailbox), and every mistake comes back with a plain "how to fix" line instead of a dead end.

What it can do

Ask in plain words — "what's waiting for my reply?", "forward the printer invoice to accounting", "put a call with Sam on Tuesday at 1pm", "save the PDFs from the contract email". Under the hood:

📥 Triage — "what needs my attention?"
