Unlisted staging preview

Apple Mail and Calendar, securely connected.

A local macOS bridge that allows a selected MCP client to use only the Mail accounts and calendars you explicitly choose.

The beta is not available yet. This is a design and documentation preview. There is intentionally no download link: signing, Apple notarization, and clean-Mac acceptance must pass first.

How you use it

Ask in everyday language. Stay in control.

The bridge connects ChatGPT desktop or Codex to Apple Mail and Apple Calendar on the same Mac. It translates your request into a local, account-scoped action.

You ChatGPT or Codex local bridge Mail and Calendar

  1. Install and connect

    Install the app, approve the macOS permission dialogs yourself, and connect the local MCP helper once.

  2. Choose the scope

    Select the Mail accounts and individual calendars the bridge may use. Nothing is selected automatically.

  3. Ask naturally

    Tell ChatGPT or Codex what you want to find, draft, change, move, schedule, or remove.

  4. Review protected actions

    Sending email and deleting Mail or Calendar items require your one-time approval in the bridge.

What you can ask

Apple Mail

  • “Find the latest invoice in my Gmail account.”
  • “Create a reply draft for Femke.”
  • “Mark this message as read and move it to Archive.”

A draft remains unsent until you explicitly ask to send it and approve that action.

Apple Calendar

  • “Schedule a personal appointment tomorrow at 9:00 AM.”
  • “Repeat this every weekday and alert me at the start time.”
  • “Move next week's appointment to Friday afternoon.”

Created and updated events are saved in a selected calendar. Deletion still requires approval.

Explicit selection

You select Mail accounts and calendars separately. New accounts are never selected automatically.

Protected actions

Sending mail and deleting Mail or Calendar items require one-time confirmation in the bridge.
