Selenium MCP Server

A Model Context Protocol (MCP) server that provides comprehensive Selenium WebDriver automation tools for AI assistants and applications. This server enables automated web browser interactions, testing, and scraping through a standardized interface.

🚀 Overview

The Selenium MCP Server bridges the gap between AI models and web automation by providing a robust set of tools for browser control, element interaction, and web testing. Built with TypeScript and modern ES modules, it offers type-safe browser automation capabilities through the Model Context Protocol.

✨ Key Features

• Multi-Browser Support: Chrome, Firefox, and Edge browser automation
• Comprehensive Element Interaction: Click, type, hover, drag & drop, file uploads
• Advanced Navigation: Forward, backward, refresh, window management
• Wait Strategies: Intelligent waiting for elements and page states
• Type Safety: Full TypeScript implementation with Zod validation

🤝 Integration

MCP Client Integration

Configure your MCP client to connect to the Selenium server:

You can install the package using either npm, or Smithery

Using npm:

npm install -g selenium-webdriver-mcp@0.1.2

Using Smithery

To install Selenium MCP for Claude Desktop automatically via Smithery:

npx @smithery/cli install @pshivapr/selenium-mcp --client claude

Installation in VS Code

Install the Selenium MCP server in VS Code using one of these buttons:

Alternatively, you can install the Selenium MCP server using the VS Code CLI:

# For VS Code
code --add-mcp '{"name":"Selenium","command":"npx","args":["selenium-webdriver-mcp"]}'

# For VS Code Insiders
code-insiders --add-mcp '{"name":"Selenium","command":"npx","args":["selenium-webdriver-mcp"]}'

After installation, the pshivapr Selenium MCP server will be available for use with your GitHub Copilot agent in VS Code.

⚙️ Configuration

Browser Options

Configure browser-specific settings when opening a browser:

// Chrome options example
{
  "browser": "chrome",
  "options": {
    "headless": false,
    "windowSize": {
      "width": 1920,
      "height": 1080
    },
    "args": [
      "--disable-web-security",
      "--disable-dev-shm-usage"
    ]
  }
}

Supported Browser Options

• headless: Run browser in headless mode
• windowSize: Set initial window dimensions
• args: Additional browser arguments
• binaryPath: Custom browser binary path
• userDataDir: Custom user data directory

Element Locator Examples

// By ID
{ "by": "id", "value": "login-button" }

// By CSS Selector
{ "by": "css", "value": ".submit-btn" }

// By XPath
{ "by": "xpath", "value": "//button[text()='Submit']" }

// By Name
{ "by": "name", "value": "username" }

// By Class Name
{ "by": "class", "value": "error-message" }

// By Tag Name
{ "by": "tag", "value": "input" }

📖 Usage Examples

Basic Web Automation

// Open browser
await tool("browser_open", { 
  browser: "chrome", 
  options: { headless: false } 
});

// Navigate to website
await tool("browser_navigate", { 
  url: "https://example.com" 
});

// Find and click a button
await tool("browser_click", { 
  by: "id", 
  value: "submit-button" 
});

// Type in a form field
await tool("browser_type", { 
  by: "css", 
  value: "#username", 
  text: "myusername" 
});

🐛 Troubleshooting

Common Issues

Browser not starting:

• Ensure the target browser is installed
• Check browser binary path in options
• Verify no other processes are using the browser

Element not found:

• Increase timeout value
• Verify locator strategy and value
• Check if element is in an iframe
• Wait for page to fully load

Module resolution errors:

npm run clean
