Mobile Next MCP Server

Instructions

Implementation Reference

• src/server.ts:356-370 (registration)

  Registration of the 'mobile_double_tap_on_screen' MCP tool, including input schema (device, x, y) and handler that calls doubleTap on the device-specific Robot instance.

  tool(
  	"mobile_double_tap_on_screen",
  	"Double Tap Screen",
  	"Double-tap on the screen at given x,y coordinates.",
  	{
  		device: z.string().describe("The device identifier to use. Use mobile_list_available_devices to find which devices are available to you."),
  		x: z.number().describe("The x coordinate to double-tap, in pixels"),
  		y: z.number().describe("The y coordinate to double-tap, in pixels"),
  	},
  	async ({ device, x, y }) => {
  		const robot = getRobotFromDevice(device);
  		await robot!.doubleTap(x, y);
  		return `Double-tapped on screen at coordinates: ${x}, ${y}`;
  	}
  );

• src/server.ts:365-369 (handler)

  The tool handler function for mobile_double_tap_on_screen, which retrieves the Robot for the device and invokes its doubleTap method.

  async ({ device, x, y }) => {
  	const robot = getRobotFromDevice(device);
  	await robot!.doubleTap(x, y);
  	return `Double-tapped on screen at coordinates: ${x}, ${y}`;
  }

• src/android.ts:446-450 (helper)

  AndroidRobot.doubleTap implementation: performs two taps at the coordinates with a 100ms delay between them.

  public async doubleTap(x: number, y: number): Promise<void> {
  	await this.tap(x, y);
  	await new Promise(r => setTimeout(r, 100)); // short delay
  	await this.tap(x, y);
  }

• src/ios.ts:194-197 (helper)

  IosRobot.doubleTap implementation: delegates to WebDriverAgent (wda).doubleTap.

  public async doubleTap(x: number, y: number): Promise<void> {
  	const wda = await this.wda();
  	await wda.doubleTap(x, y);
  }

• src/mobile-device.ts:184-188 (helper)

  MobileDevice.doubleTap implementation (for simulators): performs two sequential taps.

  public async doubleTap(x: number, y: number): Promise<void> {
  	// TODO: should move into mobilecli itself as "io doubletap"
  	await this.tap(x, y);
  	await this.tap(x, y);
  }
