Implementation Reference
- puppeteer.py:822-879 (handler)The handler function for the MCP tool 'type_text'. It connects to the Android device using uiautomator2, enables fast input IME, and uses device.send_keys() to type the provided text, optionally clearing the field first. The @mcp.tool() decorator registers it as an MCP tool.@mcp.tool() async def type_text(text: str, device_id: str = None, clear_first: bool = False) -> dict: """Type text into the currently focused input field on the Android device/emulator.
