Implementation Reference
- puppeteer.py:448-508 (handler)The handler function for the MCP tool 'press'. It performs a tap at the specified coordinates (x, y) on an Android device/emulator. If a duration is provided, it executes a long press using a swipe gesture from the point to itself. Uses ADB shell input commands via subprocess.

The tool name is derived from the function name 'press'.
@mcp.tool() - puppeteer.py:449-450 (schema)Input schema defined by function parameters: x (int, required), y (int, required), device_id (str, optional), duration (int, optional). Returns dict with success status, message, coordinates, etc. Docstring provides description.
