Expo Android MCP
Automates Android emulators and devices through ADB commands exposed as MCP tools. You get UI inspection with element parsing, tap and swipe gestures, text input, app launching, and screenshot capture. The inspect tool returns a structured element tree you can query by text, content description, resource ID, or class. Useful for building automated UI tests, screen scrapers, or any workflow that needs to drive an Android device programmatically. Handles device selection automatically or lets you target specific serials. Requires Android SDK platform-tools installed and a connected emulator or physical device.
