Why It Exists

Local-first

Your files stay on your computer. ChatGPT calls tools only after authorization.

OAuth-ready

Supports discovery metadata, Dynamic Client Registration, PKCE, and bearer tokens.

Operator-friendly

Use a fixed HTTPS tunnel and launchd to keep the bridge alive for long-running work.

Activity console

Open the local `/app` console to inspect tool calls, cloud downloads, audit events, and setup state.
