WebDriverIO MCP Server

A Model Context Protocol (MCP) server that enables Claude Desktop to interact with web browsers and mobile applications using WebDriverIO. Automate Chrome, Firefox, Edge, and Safari browsers plus iOS and Android apps—all through a unified interface.

Installation

Setup

Option 1: Configure Claude Desktop or Claude Code (Recommended)

Add the following configuration to your Claude MCP settings:

{
  "mcpServers": {
    "wdio-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@wdio/mcp"
      ]
    }
  }
}

Option 2: Global Installation

npm i -g @wdio/mcp

Then configure MCP:

{
  "mcpServers": {
    "wdio-mcp": {
      "command": "wdio-mcp"
    }
  }
}

Note: The npm package is @wdio/mcp, but the executable binary is wdio-mcp.

Restart Claude Desktop

⚠️ You may need to fully restart Claude Desktop. On Windows, use Task Manager to ensure it's completely closed before restarting.

Usage Examples

Real-World Test Cases

Example 1: Testing Demo Android App (Book Scanning)

Test the Demo Android app at C:\Users\demo-liveApiGbRegionNonMinifiedRelease-3018788.apk on emulator-5554:
1. Start the app with auto-grant permissions
2. Get visible elements on the onboarding screen
3. Tap "Skip" to bypass onboarding
4. Verify main screen loads
5. Take a screenshot

Example 2: Testing World of Books E-commerce Site

You are a Testing expert, and want to assess the basic workflows of worldofbooks.com:
- Open World of Books (accept all cookies)
- Get visible elements to see navigation structure
- Search for a fiction book
- Choose one and validate if there are NEW and used book options
- Report your findings at the end

Browser Automation

Basic web testing prompt:

You are a Testing expert, and want to assess the basic workflows of a web application:
- Open World of Books (accept all cookies)
- Search for a fiction book
- Choose one and validate if there are NEW and used book options
- Report your findings at the end

Browser configuration options:

// Default settings (headed mode, 1280x1080)
start_browser()

// Firefox
start_browser({browser: 'firefox'})

// Edge
start_browser({browser: 'edge'})

// Safari (headed only; requires macOS)
start_browser({browser: 'safari'})

// Headless mode
start_browser({headless: true})

// Custom dimensions
start_browser({windowWidth: 1920, windowHeight: 1080})

// Headless with custom dimensions
start_browser({headless: true, windowWidth: 1920, windowHeight: 1080})

// Pass custom capabilities (e.g. Chrome extensions, profile, prefs)
start_browser({
  headless: false,
  capabilities: {
    'goog:chromeOptions': {
      args: ['--user-data-dir=/tmp/wdio-mcp-profile', '--load-extension=/path/to/unpacked-extension']
    }
  }
})

Mobile App Automation

Testing an iOS app on simulator:

Test my iOS app located at /path/to/MyApp.app on iPhone 15 Pro simulator:
1. Start the app session
2. Tap the login button
3. Enter "testuser" in the username field
4. Take a screenshot of the home screen
5. Close the session

Preserving app state between sessions:

Test my Android app without resetting data:
1. Start app session with noReset: true and fullReset: false
2. App launches with existing login state and user data preserved
3. Run test scenarios
4. Close session (app remains installed with data intact)

Testing an iOS app on real device:
