## AI overview

This tutorial explains how Claude Code, Cursor, Codex, and other MCP-enabled coding agents can use Maestro MCP to explore mobile app interfaces on iOS Simulators, Android emulators, physical Android devices, and Chromium, then save the tested steps as reusable Flow files. The saved Flows can be rerun through an agent or the CLI, including in CI, to detect UI changes.

## Source excerpt

Have Claude Code, Cursor or Codex run a UI test on an iOS Simulator or Android emulator, then save it as a Flow and run the same test again.
