The cart says $0
mobile-mcp lets the agent confirm the total is wrong. Argent shows it whether the cart request failed on iOS and, in React Native apps, what the server sent back.
Argent vs. mobile-mcp
Your agent taps Checkout, waits, takes a screenshot and reports back: the spinner is still spinning. Accurate, but you knew that.
mobile-mcp, from Mobile Next, launches apps, taps, types and records the screen on iOS and Android. Argent does that too, then looks inside the app: which requests failed on iOS, and why the screen is slow.
Based on each tool's public documentation, checked October 20, 2026.
What your agent can see after the tap
A slow scroll, explained
Argent profiles the app and shows the agent each freeze. On iOS it also says where the freeze came from and what to try first.
A closer look at React Native apps
If your app is built with React Native or Expo, the agent can also read console logs, run code in the live app and look through its components.
Keep the run that worked
Ask the agent to record a path that worked, and Argent saves it as a YAML flow your agent and CI can replay. mobile-mcp leaves that to Mobilewright, a separate library.
Argent and mobile-mcp, tool by tool
Both connect a coding agent to iOS and Android apps over MCP. They differ most in what the agent can see inside the app.

mobile-mcp questions, answered
Find out why the spinner keeps spinning
With Argent, your agent taps through your iOS and Android app and finds out why a screen is slow or empty. The paths that work can become end-to-end tests.
