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 'test@email.com' into the current field"

Debugging

"Show me the last 50 Flutter logs"
"Are there any crash logs for my app?"
"What's the memory usage of com.myapp?"

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"

Performance Testing

"Set animation scale to 0 and run through the app"
"Get frame stats for my app - is there any jank?"
"What's the GPU rendering performance?"

Device Simulation

"Change the screen to 1080x1920 to simulate a smaller phone"
"Rotate to landscape mode"
"Set location to San Francisco (37.7749, -122.4194)"

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

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