Give your coding agent eyes and hands, so it can e2e test your mobile app and you know it works before you ship.

The Maestro MCP reads our live docs, and we update those every week. So it keeps getting better and smarter without us shipping any code

Does your app still work the way it should? Install Maestro MCP, then ask Claude Code, Codex or whatever coding agent you use to test it end to end, like the pros do.

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.

Maestro MCP is the part that touches the phone. The agent decides what to test, Maestro taps, types and long-presses for it, and here it's adding and deleting a habit in Habitica.

This is what agentic UI testing looks like, Claude Code runs a full ASOS shopping flow on Android through the Maestro MCP, and even closes the promo pop-up that showed up halfway through.

We are entering the agentic era of E2E tests and agents interacting directly with Android emulators. Things are evolving quickly as we speak. Maestro MCP is a game changer in this matter 🔥

Told @claudeai Code to browse Google News, follow the Technology topic and open the top story, and the Maestro MCP gave it the Android emulator to go do it.

Claude wrote its own QA test plan in Simplenote, then pinned it. Every tap through Maestro MCP. Open source.

Building a Wikipedia test in this Office Hours clip, Claude Code noticed the first-run tooltips and dismissed each one on its own. Nobody told it they would appear or how to handle them. It wrote the test and reran it, all through the Maestro MCP.
