Implementation Reference
- src/adb_mcp_server/server.py:57-61 (handler)The handler function for the 'list_devices' tool. It is decorated with @mcp.tool() which registers it with the FastMCP server. The function executes `adb devices -l` via the run_adb helper to list connected Android devices with details.
@mcp.tool() def list_devices() -> str: """List all connected Android devices with details""" return run_adb(["devices", "-l"]) - src/adb_mcp_server/server.py:24-39 (helper)Helper function used by list_devices to execute ADB commands safely, handling errors, timeouts, and device selection.
def run_adb(args: list[str], device_serial: str | None = None, timeout: int = 30) -> str: """Run an ADB command and return output""" cmd = ["adb"] if device_serial: cmd.extend(["-s", device_serial]) cmd.extend(args) try: result = subprocess.run(cmd, capture_output=True, text=True, timeout=timeout) if result.returncode != 0 and result.stderr: return f"Error: {result.stderr}" return result.stdout except subprocess.TimeoutExpired: return "Error: Command timed out" except Exception as e: return f"Error: {str(e)}"
