mobile-debug-mcp

Mobile Debug Tools

A minimal, secure MCP server for AI-assisted mobile development. Build, install, interact and inspect Android/iOS apps from an MCP-compatible client.

Support:

• KMP
• Android
• iOS
• Flutter - not tested
• React native - not tested

Requirements

• Node.js >= 18
• Android SDK (adb) for Android support
• Xcode command-line tools for iOS support
• idb for iOS device support

Environment Setup

The server discovers Android and iOS tools automatically from standard locations by default. Manual environment setup is still supported, but it should be treated as the fallback for non-standard installs, overrides, or reproducible pinned toolchains.

Use explicit paths when:

• you have multiple SDKs installed
• the tools live outside standard locations
• you want deterministic setup across machines
• automatic discovery does not find the expected binary

Leave the variables unset when:

• the tools are already on PATH
• the standard Android and Xcode locations are enough

Common environment variables:

• ADB_PATH: explicit path to adb
• ANDROID_SDK_ROOT or ANDROID_HOME: Android SDK root
• XCRUN_PATH: explicit path to xcrun
• MCP_IDB_PATH or IDB_PATH: explicit path to idb
• GRADLE_JAVA_HOME or JAVA_HOME: Java home for Gradle-backed operations

For normal use, call get_system_status first. It reports the detected host, Android, and iOS toolchain state so the client can decide whether automatic discovery is sufficient or whether explicit overrides are needed.

Configuration

Android setup

Recommended when you want Android only, or when you want to make the Android toolchain explicit.

{
  "mcpServers": {
    "mobile-debug": {
      "command": "npx",
      "args": ["--yes","mobile-debug-mcp","server"],
      "env": {
        "ADB_PATH": "/path/to/adb",
        "ANDROID_SDK_ROOT": "/path/to/android/sdk",
        "GRADLE_JAVA_HOME": "/path/to/jdk"
      }
    }
  }
}

For Android-only setups, XCRUN_PATH and IDB_PATH are not required unless you want to pin them explicitly.

iOS setup

Recommended when you want iOS simulator or device support, or when idb lives in a non-standard location.

{
  "mcpServers": {
    "mobile-debug": {
      "command": "npx",
      "args": ["--yes","mobile-debug-mcp","server"],
      "env": {
        "XCRUN_PATH": "/usr/bin/xcrun",
        "MCP_IDB_PATH": "/path/to/idb",
        "IDB_PATH": "/path/to/idb"
      }
    }
  }
}

For iOS-only setups, ADB_PATH and ANDROID_SDK_ROOT are not required unless you want to pin them explicitly.

Codex

Use STDIO

command: npx

args:

• --yes
• mobile-debug-mcp

environment variables:

• ADB_PATH: /path/to/adb
• XCRUN_PATH: /usr/bin/xcrun
• IDB_PATH: /path/to/idb
• MCP_IDB_PATH: /path/to/idb
• ANDROID_SDK_ROOT: /path/to/android/sdk
• GRADLE_JAVA_HOME: /path/to/jdk
• JAVA_HOME: /path/to/jdk

If you are unsure whether the environment is configured correctly, run get_system_status first. It reports the detected host, Android, and iOS toolchain state in a structured form.

Usage

For clients that support Agent Plugins, the agent-plugin package installs the MCP server configuration together with the existing usage skill. Direct npm/MCP configuration above remains supported.

Examples:

Crash fixing:

I have a crash on the app, can you diagnose it, fix and validate using the mcp tools available

Feature building:

Add a button, hook into the repository and confirm API request successful
