An MCP (Model Context Protocol) server that provides browser automation capabilities using Playwright. This allows you to navigate websites, extract content, and perform web tasks through simple prompts.

Features

• Navigate to URLs - Open and load web pages
• Extract page content - Get text or HTML content from pages
• Get page titles - Retrieve page titles
• Take screenshots - Capture page screenshots
• Interact with pages - Click elements, type text, wait for selectors

Installation

1. Install dependencies:

npm install

2. Install Playwright browsers:

npx playwright install chromium

Configuration

For Cursor IDE

Cursor uses an MCP configuration file located at:

• Windows: %USERPROFILE%\.cursor\mcp.json (e.g., C:\Users\YourName\.cursor\mcp.json)
• macOS/Linux: ~/.cursor/mcp.json

Quick Setup (Windows)

1. Automated setup: Run the provided PowerShell script:

   powershell -ExecutionPolicy Bypass -File setup-cursor-config.ps1
   

2. Manual setup: Create or edit the file at C:\Users\YourName\.cursor\mcp.json and add:

   {
     "mcpServers": {
       "playwright-browser": {
         "command": "node",
         "args": [
           "D:\\Sumit\\Code\\vibe\\mcp-practice\\src\\server.js"
         ],
         "cwd": "D:\\Sumit\\Code\\vibe\\mcp-practice"
       }
     }
   }
   

   Important: Update the paths to match your actual project location.

Quick Setup (macOS/Linux)

1. Create the directory if it doesn't exist:

   mkdir -p ~/.cursor
   

2. Create or edit ~/.cursor/mcp.json:

   {
     "mcpServers": {
       "playwright-browser": {
         "command": "node",
         "args": [
           "/full/path/to/mcp-practice/src/server.js"
         ],
         "cwd": "/full/path/to/mcp-practice"
       }
     }
   }
   

After Configuration

1. Restart Cursor completely for the changes to take effect
2. The MCP server will automatically start when you use browser-related prompts
3. Verify it's working by trying: "Navigate to https://example.com and summarize the page"

If you're using Claude Desktop instead:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json
