# WebDriverIO MCP Server

A Model Context Protocol (MCP) server that enables AI assistants 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

[![mcp MCP server](https://glama.ai/mcp/servers/webdriverio/mcp/badges/score.svg)](https://glama.ai/mcp/servers/webdriverio/mcp)

Add the following configuration to your MCP client settings:

**Standard config** (works in most clients):

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

----
> ⚠️ **Restart Required**: After adding the configuration, fully restart your MCP client to apply the changes.

### Option 2: Global Installation

If you prefer to install globally:

```bash
npm install -g @wdio/mcp
```

Then use `wdio-mcp` as the command:

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

📖 **Need help?** Follow the [MCP install guide](https://modelcontextprotocol.io/quickstart/user).

### HTTP Transport (for non-subprocess clients)

By default the server uses **stdio** (subprocess) transport. For clients that cannot launch subprocesses (e.g.
llama.cpp, OpenAI Codex secure mode), enable HTTP transport:

```bash
npx @wdio/mcp --http --port 3000
```

| Flag               | Default                            | Description                                             |
|--------------------|------------------------------------|---------------------------------------------------------|
| `--http`           | —                                  | Enable HTTP transport mode                              |
| `--port`           | `3000`                             | Port to listen on                                       |
| `--allowedHosts`   | `localhost,127.0.0.1,::1`          | Allowed `Host` header values (DNS rebinding protection) |
| `--allowedOrigins` | _(none — browser clients blocked)_ | Allowed `Origin` values for CORS. Use `*` to allow all. |

Then point your MCP client at `http://localhost:3000/mcp`.

### Prerequisites For Mobile App Automation

- **Appium Server**: Install globally with `npm install -g appium`
- **Platform Drivers**:
    - iOS: `appium driver install xcuitest` (requires Xcode on macOS)
    - Android: `appium driver install uiautomator2` (requires Android Studio)
- **Devices/Emulators**:
    - iOS Simulator (macOS) or physical device
    - Android Emulator or physical device
- **For iOS Real Devices**: You'll need the device's UDID (Unique Device Identifier)
    - **Find UDID on macOS**: Connect device → Open Finder → Select device → Click device name/model to reveal UDID
    - **Find UDID on Windows**: Connect device → iTunes or Apple Devices app → Click device icon → Click "Serial Number"
      to reveal UDID
    - **Xcode method**: Window → Devices and Simulators → Select device → UDID shown as "Identifier"

Start the Appium server before using mobile features:

```bash
appium
# Server runs at http://127.0.0.1:4723 by default
```

## Cloud Providers

Run browser and mobile app tests on cloud real devices and browsers without any local setup. Currently supports

<summary>Digital.ai Testing</summary>

```bash
export DIGITALAI_CLOUD_URL=https://your-cloud.example.com
export DIGITALAI_ACCESS_KEY=your_access_key
```

```json
{
  "mcpServers": {

}
```

| `DIGITALAI_CLOUD_URL` | Digital.ai cloud host, e.g. `https://your-cloud.example.com` (required) |
| `DIGITALAI_ACCESS_KEY` | Digital.ai access key (required) |

The access key is sent via the `digitalai:options` capability (mobile) or the flat `digitalai:accessKey` capability (web).

**Report pass/fail status:** WebdriverIO defaults to the BiDi protocol, over which Digital.ai's cloud cannot observe command failures — so reports default to "Passed". To make the cloud reflect actual pass/fail, opt in to classic WebDriver per session:

```js
start_session({
  provider: 'digitalai', platform: 'browser', browser: 'chrome',
