Webdriverio MCP

WebDriverIO MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to interact with web browsers, local Electron applications, and mobile applications using WebdriverIO. Automate Chrome, Firefox, Edge, Safari, Electron, iOS, and Android through a unified interface.

Installation

Add the following configuration to your MCP client settings:

Standard config (works in most clients):

{

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

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS), %APPDATA%\Claude\claude_desktop_config.json (Windows), or ~/.config/Claude/claude_desktop_config.json (Linux):

{

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

Claude Code

claude mcp add wdio-mcp -- npx -y @wdio/mcp@latest

Cline

Add to your VS Code settings.json or cline_mcp_settings.json file:

{

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

Cursor

Go to Cursor Settings → MCP → Add new MCP Server, or create .cursor/mcp.json:

{

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

Codex

Use the Codex CLI:

codex mcp add wdio-mcp npx "@wdio/mcp@latest"

Or edit ~/.codex/config.toml:

[mcp_servers.wdio-mcp]

command = "npx" args = ["@wdio/mcp@latest"]

Goose

Go to Advanced settings → Extensions → Add custom extension, or run:

goose configure

Or edit ~/.config/goose/config.yaml:

extensions:

wdio-mcp: name: WebDriverIO MCP cmd: npx args: [ -y, "@wdio/mcp@latest" ] enabled: true type: stdio

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

{

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

Zed

Edit Zed settings (~/.config/zed/settings.json):

{

"context_servers": { "wdio-mcp": { "source": "custom", "command": "npx", "args": [ "-y", "@wdio/mcp@latest" ] } } }

VS Code (Copilot)

code --add-mcp '{"name":"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:

npm install -g @wdio/mcp

Then use wdio-mcp as the command:

{

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

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:

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

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:

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 BrowserStack, Sauce Labs, LambdaTest, TestingBot, and Digital.ai Testing.

Prerequisites

Set your provider credentials as environment variables or in your MCP client config:

BrowserStack

export BROWSERSTACK_USERNAME=your_username

export BROWSERSTACK_ACCESS_KEY=your_access_key

{

"mcpServers": { "wdio-mcp": { "command": "npx", "args": ["-y", "@wdio/mcp@latest"], "env": { "BROWSERSTACK_USERNAME": "your_username", "BROWSERSTACK_ACCESS_KEY": "your_access_key" } } } }

Sauce Labs

export SAUCE_USERNAME=your_username

export SAUCE_ACCESS_KEY=your_access_key

{

"mcpServers": { "wdio-mcp": { "command": "npx", "args": ["-y", "@wdio/mcp@latest"], "env": { "SAUCE_USERNAME": "your_username", "SAUCE_ACCESS_KEY": "your_access_key" } } } }

| SAUCE_USERNAME | Sauce Labs username (required) | | SAUCE_ACCESS_KEY | Sauce Labs access key (required) |

The data center is set per-session via the region parameter in start_session (defaults to eu-central-1).

LambdaTest (TestMu)

export TESTMU_USERNAME=your_username

export TESTMU_ACCESS_KEY=your_access_key

{

"mcpServers": { "wdio-mcp": { "command": "npx", "args": ["-y", "@wdio/mcp@latest"], "env": { "TESTMU_USERNAME": "your_username", "TESTMU_ACCESS_KEY": "your_access_key" } } } }

| TESTMU_USERNAME | LambdaTest username (required) | | TESTMU_ACCESS_KEY | LambdaTest access key (required) |

TestingBot

export TESTINGBOT_KEY=your_key

export TESTINGBOT_SECRET=your_secret

{

"mcpServers": { "wdio-mcp": { "command": "npx", "args": ["-y", "@wdio/mcp@latest"], "env": { "TESTINGBOT_KEY": "your_key", "TESTINGBOT_SECRET": "your_secret" } } } }

| TESTINGBOT_KEY | TestingBot key (required) | | TESTINGBOT_SECRET | TestingBot secret (required) |

Digital.ai Testing

export DIGITALAI_CLOUD_URL=https://your-cloud.example.com

export DIGITALAI_ACCESS_KEY=your_access_key

{

"mcpServers": { "wdio-mcp": { "command": "npx", "args": ["-y", "@wdio/mcp@latest"], "env": { "DIGITALAI_CLOUD_URL": "https://your-cloud.example.com", "DIGITALAI_ACCESS_KEY": "your_access_key" } } } }

| 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:

start_session({

provider: 'digitalai', platform: 'browser', browser: 'chrome', os: 'Windows 10', capabilities: { 'wdio:enforceWebDriverClassic': true } })

(Pure client-side assertion failures still report as "Passed" — only failures that reach the cloud as WebDriver command errors are detected.)

Mobile (Appium): configure your Digital.ai project for Appium-server execution and pick its default Appium version via the project's "Manage default Appium server version" setting — the version is chosen at the project level (and tracks the versions your cloud supports), so this MCP does not pin one. See Appium Server Test Execution.

Browser Sessions

Run a browser on a specific OS/version combination:

// BrowserStack

start_session({ provider: 'browserstack', platform: 'browser', browser: 'chrome', // chrome | firefox | edge | safari browserVersion: 'latest', // default: latest os: 'Windows', // e.g. "Windows", "OS X" osVersion: '11', // e.g. "11", "Sequoia" reporting: { project: 'My Project', build: 'v1.2.0', session: 'Login flow' } })

// Sauce Labs start_session({ provider: 'saucelabs', platform: 'browser', browser: 'chrome', os: 'Windows', // combined with osVersion → platformName osVersion: '11', // e.g. "11", "15" (numbered Mac naming) region: 'eu-central-1', // default: eu-central-1 reporting: { build: 'v1.2.0', session: 'Login flow' } })

// LambdaTest start_session({ provider: 'testmu', platform: 'browser', browser: 'chrome', os: 'Windows', // combined with osVersion → platformName osVersion: '11', // e.g. "11", "Sequoia" (optional) reporting: { project: 'My Project', build: 'v1.2.0', session: 'Login flo
