Phone Harness MCP Gives Agents Real Phones

Phone Harness turns mobile apps into an agent-accessible surface, pushing automation beyond APIs and browsers into real device workflows.

• –MCP exposes familiar controls for screenshots, OCR, accessibility data, taps, swipes, typing, and app management
• –Cloud Android emulators start at 5¢ per minute, while hosted real iPhones use a subscription model
• –Real devices enable workflows involving persistent logins, phone numbers, SMS, and 2FA
• –The convenience comes with a serious trust problem: agents need strict approval gates before sending, buying, deleting, or changing settings
• –Camera, Face ID, multi-touch, and some locked-device flows remain practical limitations
