+Control implementations. MCP wraps this HTTP API without API keys. Changes
+require a separate user approval; power also retains its password prompt. The

+for a message. Screenshot context is separately opt-in. Model replies cannot
+operate the headset. Tools → Open assistant opens the page; the linked guide
+covers putting it in a Chromium panel on the Frame.
