Connect Antigravity to Agent Master Key

Agent Master Key (AMK) gives Antigravity its own scoped, revocable key while your real provider keys stay in an encrypted vault on your Mac. AMK connects Antigravity as a one-click connect harness.

How it works

1. Download Agent Master Key and connect a provider (your key never leaves the Mac).
2. Open Connect an agent and pick Antigravity. AMK creates a scoped agent key and merges the connection into the config below (backup first).
3. Restart Antigravity so it picks up the AMK connection.

Config file

~/Library/Application Support/Antigravity/User/mcp.json

The entry points at AMK's local launcher only — it never contains your provider keys or an agent key. Revoke Antigravity's access anytime from the AMK dashboard; revocation takes effect immediately and does not touch your other agents.
