Example Prompts

Basic Usage

• "Take a screenshot of my phone"

• "List all installed apps containing 'flutter'"
• "What's currently on screen? Get all the text"

UI Testing

• "Find the login button and tap it"
• "Scroll down until you find 'Settings'"
• "Get all clickable elements and their positions"
• "Type '[e-mail]' into the current field"

Debugging

• "Show me the last 50 Flutter logs"

Visual QA

• "Capture this screen for comparison with Figma"
• "Take a screenshot and tell me about the UI structure"
• "Set the font scale to 1.3 and take a screenshot for accessibility testing"

Extending

Add new tools easily:

@mcp.tool()
def my_custom_tool(param: str, device_serial: str | None = None) -> str:
    """Description shown to AI"""
    return run_adb(["shell", "your-command", param], device_serial)

Tips for Flutter Development

1. Speed up tests: Use set_animation_scale(0) to disable animations
2. Visual QA: Use capture_screen_for_comparison() with Figma MCP
3. Debug logs: get_flutter_logs() filters Flutter-specific output
4. Hot reload: Keep flutter run terminal open, use device for interaction
5. Responsive testing: Use change_screen_size() and change_density()
