Configuring in Cursor

Note: Requires Cursor version 0.45.6+

The WebScraping.AI MCP server can be configured in two ways in Cursor:

1. Project-specific Configuration (recommended for team projects): Create a .cursor/mcp.json file in your project directory:

   {
     "servers": {
       "webscraping-ai": {
         "type": "command",
         "command": "npx -y webscraping-ai-mcp",
         "env": {
           "WEBSCRAPING_AI_API_KEY": "your-api-key",
           "WEBSCRAPING_AI_CONCURRENCY_LIMIT": "5",
           "WEBSCRAPING_AI_ENABLE_CONTENT_SANDBOXING": "true"
         }
       }
     }
   }
   

2. Global Configuration (for personal use across all projects): Create a ~/.cursor/mcp.json file in your home directory with the same configuration format as above.

If you are using Windows and are running into issues, try using cmd /c "set WEBSCRAPING_AI_API_KEY=your-api-key && npx -y webscraping-ai-mcp" as the command.

This configuration will make the WebScraping.AI tools available to Cursor's AI agent automatically when relevant for web scraping tasks.
