What it does

Mobile Device MCP lets an agent tap, scroll, type, take screenshots, read the UI tree and run code on real iOS and Android devices and emulators. It works with several devices at once. The architecture has three layers: lightweight on-device HTTP servers on UIAutomator and XCUITest, a UI tree filter that normalizes both formats into a flat element list, and the external MCP server. On first use the server installs the driver app itself, allocates a port and waits for readiness. After that calls are proxied over localhost. Among 14 tools are `list_devices`, `screenshot`, `uitree`, `tap`, `type_text`, `launch_app`, `install_app` and `run_code`, which executes sandboxed JavaScript on the device.

Who it is for. Mobile developers and QA engineers who need to give an agent parallel work with several phones and emulators.

Good fit when

  • One scenario runs at once on several Android and iOS devices
  • The agent takes a screenshot and the element tree with no manual markup
  • An app is installed on a device from a local `.apk`, `.app` or `.ipa`
  • A native screen and an embedded WebView are described in one list

Not a fit when

  • There is no Android SDK with `adb` or Xcode
  • A test framework with reports is needed instead of manual control
  • A device cannot be left under an agent's control

Limitations

Node.js 18 or newer for `npx`, the Android SDK with `adb` on `PATH` for Android and Xcode with `xcrun` and `simctl` for the iOS simulator are required. A real iPhone additionally needs `xcodebuild`, `devicectl` and `iproxy` from libimobiledevice. Building from source requires Bun, Gradle and Xcode. Driver ports are set with the `MDMS_PORT_ANDROID` and `MDMS_PORT_IOS` variables. The `run_code` tool runs code on the device in a sandbox, but the agent overall gets full control of the phone, including app installation.

How to disable. Remove the `mobile-device-mcp` entry from the client with `claude mcp remove mobile-device-mcp` and delete the driver app from the device.

FAQ

How do I connect Mobile Device MCP?

Run `claude mcp add mobile-device-mcp -- npx -y @srmorete/mobile-device-mcp@latest`. For your own ports add `-e MDMS_PORT_ANDROID=20000 -e MDMS_PORT_IOS=21000`.

What does run_code do?

It runs sandboxed JavaScript on the device: on Android in the Rhino engine with UIAutomator bindings, on iOS XCUITest-style commands are allowed.

How do several devices work?

The server discovers devices, installs a driver on first use, allocates a port and then proxies calls to each device over localhost separately.

Is a real phone needed?

No, Android emulators and iOS simulators work. A real iPhone needs `devicectl` and `iproxy`.

What is uitree?

A flat list of UI elements that normalizes UIAutomator and XCUITest trees into one format. Off-screen elements are excluded by default.

README in short

The README describes the server as a way to control iOS and Android from an agent, explains the three-layer architecture and lists the tools. `run_code`, requirements, installation, build and license are covered separately.
