Phone Harness is released as open source, letting agents control personal or cloud phones
Phone Harness is released as open source, letting agents use the user's own phone or a cloud iPhone/Android, and can test and use real mobile apps, send messages and make calls, and obtain 2FA verification codes. The project is accessed through MCP, CLI, or API, and Larsen Cundric added that it can also operate apps without a web version, such as ordering food, hailing a ride, or making appointments within the app.

Body
Most of life still runs through a mobile device.
And until now agents couldn't touch it.
Phone Harness (open source btw) gives your agent the ability to use your own or a cloud phone:
> test real mobile apps > message and call people > use apps that have no web version > order food or a ride in the app > book that appointment only the app can do
Excited to see where @shawn_pana takes this 🙏
