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.

Local, scoped, and under your control

Local processing

The bridge runs on your Mac. Straeder does not receive messages, calendar items, or account details through the app.

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.

What the local alpha supports

Planned first beta

Apple silicon (arm64) running macOS 15.6–26.x. Codex or ChatGPT desktop runs on the same Mac; ChatGPT web cannot start the local stdio helper directly.

Download unavailable

No DMG has been published or approved as a beta. Before downloading, the final page will always show the version, build, architecture, and SHA-256.
