A Playwright-based Node.js tool that bypasses search engine anti-scraping mechanisms to execute Google searches and extract results. It can be used directly as a command-line tool or as a Model Context Protocol (MCP) server to provide real-time search capabilities to AI assistants like Claude.

This tool has been specially adapted for Windows environments:

1. .cmd files are provided to ensure command-line tools work properly in Windows Command Prompt and PowerShell
2. Log files are stored in the system temporary directory instead of the Unix/Linux /tmp directory
3. Windows-specific process signal handling has been added to ensure proper server shutdown
4. Cross-platform file path handling is used to support Windows path separators

When using the --get-html option, the output will include information about the HTML content:

{
  "query": "playwright automation",
  "url": "https://www.google.com/",
  "originalHtmlLength": 1291733,
  "cleanedHtmlLength": 456789,
  "htmlPreview": "<!DOCTYPE html><html itemscope=\"\" itemtype=\"http://schema.org/SearchResultsPage\" lang=\"zh-CN\"><head><meta charset=\"UTF-8\"><meta content=\"dark light\" name=\"color-scheme\"><meta content=\"origin\" name=\"referrer\">..."
}

If you also use the --save-html option, the output will include the path where the HTML was saved:

{
  "query": "playwright automation",
  "url": "https://www.google.com/",
  "originalHtmlLength": 1292241,
  "cleanedHtmlLength": 458976,
  "savedPath": "./google-search-html/playwright_automation-2025-04-06T03-30-06-852Z.html",

  "htmlPreview": "<!DOCTYPE html><html itemscope=\"\" itemtype=\"http://schema.org/SearchResultsPage\" lang=\"zh-CN\">..."
}

This project provides Model Context Protocol (MCP) server functionality, allowing AI assistants like Claude to directly use Google search capabilities. MCP is an open protocol that enables AI assistants to safely access external tools and data.

# Build the project
pnpm build

1. Edit the Claude Desktop configuration file:

   • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
     • Usually located at C:\Users\username\AppData\Roaming\Claude\claude_desktop_config.json
     • You can access it directly by entering %APPDATA%\Claude in Windows Explorer address bar

2. Add server configuration and restart Claude

{
  "mcpServers": {
    "google-search": {
      "command": "npx",
      "args": ["google-search-mcp"]
    }
  }
}

For Windows environments, you can also use the following configurations:

1. Using cmd.exe with npx:

{
  "mcpServers": {
    "google-search": {
      "command": "cmd.exe",
      "args": ["/c", "npx", "google-search-mcp"]
    }
  }
}

2. Using node with full path (recommended if you encounter issues with the above method):

{
  "mcpServers": {
    "google-search": {
      "command": "node",
      "args": ["C:/path/to/your/google-search/dist/src/mcp-server.js"]
    }
  }
}

Note: For the second method, you must replace C:/path/to/your/google-search with the actual full path to where you installed the google-search package.

After integration, you can directly use search functionality in Claude, such as "search for the latest AI research".

• TypeScript: Development language, providing type safety and better development experience
• Node.js: Runtime environment for executing JavaScript/TypeScript code
• Playwright: For browser automation, supporting multiple browsers
• Commander: For parsing command line arguments and generating help information
• Model Context Protocol (MCP): Open protocol for AI assistant integration
• MCP SDK: Development toolkit for implementing MCP servers
• Zod: Schema definition library for validation and type safety
• pnpm: Efficient package management tool, saving disk space and installation time

All commands can be run in the project root directory:

# Install dependencies
pnpm install

# Install Playwright browsers
pnpm run postinstall

# Compile TypeScript code
pnpm build

# Clean compiled output
pnpm clean

# Run in development mode
pnpm dev "search keywords"

# Run in debug mode (showing browser interface)
pnpm debug "search keywords"

# Run compiled code
pnpm start "search keywords"

# Test search functionality
pnpm test

# Run MCP server in development mode
pnpm mcp

# Run compiled MCP server
pnpm mcp:build

The tool has built-in robust error handling mechanisms:

• Friendly error messages when browser startup fails
• Automatic error status return for network connection issues
• Detailed logs for search result parsing failures
• Graceful exit and useful information return in timeout situations

• This tool is for learning and research purposes only
• Please comply with Google's terms of service and policies
• Do not send requests too frequently to avoid being blocked by Google
• Some regions may require a proxy to access Google
• Playwright needs to install browsers, which will be automatically downloaded on first use

• State files contain browser cookies and storage data, please keep them secure
• Using state files can effectively avoid Google's anti-bot detection and improve search success rate

• MCP server requires Node.js v16 or higher
• When using the MCP server, please ensure Claude Desktop is updated to the latest version
• When configuring Claude Desktop, use absolute paths to the MCP server file

• In Windows environments, you may need administrator privileges to install Playwright browsers for the first time
• If you encounter permission issues, try running Command Prompt or PowerShell as administrator
• Windows Firewall may block Playwright browser network connections; allow access when prompted
• Browser state files are saved by default in the user's home directory as .google-search-browser-state.json
• Log files are stored in the system temporary directory under the google-search-logs folder

Compared to paid search engine results API services (such as SerpAPI), this project offers the following advantages:

• Completely Free: No API call fees
• Local Execution: All searches are executed locally, no dependency on third-party services
• Privacy Protection: Search queries are not recorded by third parties
• Customizability: Fully open source, can be modified and extended as needed
• No Usage Limits: Not subject to API call count or frequency limitations
• MCP Integration: Native support for integration with AI assistants like Claude
