Agent requests reach you as approvals you decide with a biometric. On the Mac that's a menu-bar app and Touch ID. On iPhone and iPad it's Face ID, on Android the Keystore. Every decision becomes a signed receipt your backend can verify offline.
A menu-bar app. Requests appear as a popover; you approve with Touch ID. Keys live in the Secure Enclave and never leave the machine. Signed with a Developer ID certificate and notarized by Apple; updates arrive automatically.
The full approver in your pocket: pending queue, plain-language requests, severity at a glance, Face ID to decide, signed receipts in history. Keys are generated on the device and stay in the Secure Enclave.
The same approver, backed by the Android Keystore. Fingerprint or face to decide, the pending queue and receipt history in your pocket, and push the moment an agent asks.
The apps are for approvers. If you're wiring an agent to request approval, you want the SDK and the MCP server — start here. Six lines to the first approval.
