<p>Rouse Context turns your Android phone into an on-demand <a href="https://modelcontextprotocol.io/">MCP</a> (Model Context Protocol) server. An AI client connects to a URL, your phone wakes up, and a direct encrypted session is established. The client asks for what it needs — health data, notifications, app usage — your phone answers, then goes back to sleep.</p> <p>Your data stays on the device. The session runs end-to-end encrypted between the AI client and your phone; the relay that connects them only forwards that encrypted traffic and can't read it.</p> <p>Wake-ups use <a href="https://unifiedpush.org/">UnifiedPush</a>, so install a UnifiedPush distributor (for example ntfy) to be reached while the app is in the background.</p> <p>Features:</p> <ul> <li>On-demand — your phone is only reachable while a client is connected, then sleeps again. No always-on background service draining the battery.</li> <li>You stay in control — you enable each integration explicitly, and every tool call an AI client makes is recorded in an on-device audit history you can review.</li> <li>Private by design — data never leaves the device except through a live, user-approved session.</li> <li>Certificate monitoring — the app checks public transparency logs (crt.sh, or Certspotter as backup) for certificates issued to your device's address, so a forged one doesn't go unnoticed. Runs every 12 hours by default; change the interval or turn it off in Settings.</li> <li>Free and open source, with no analytics or tracking in the app.</li> </ul>
