You can configure your LLM to use these tools for web scraping tasks.\n\n### Example: Configuring Claude with MCP\n\n```javascript\nconst { Claude } = require('@anthropic-ai/sdk');\nconst { Client } = require('@modelcontextprotocol/sdk/client/index.js');\nconst { StdioClientTransport } = require('@modelcontextprotocol/sdk/client/stdio.js');\n\nconst claude = new Claude({\n apiKey: process.env.ANTHROPIC_API_KEY\n});\n\nconst transport = new StdioClientTransport({\n command: 'npx',\n args: ['-y', 'webscraping-ai-mcp'],\n env: {\n WEBSCRAPING_AI_API_KEY: 'your-api-key'\n }\n});\n\nconst client = new Client({\n name: 'claude-client',\n version: '1.0.0'\n});\n\nawait client.connect(transport);\n\n// Now you can use Claude with WebScraping.AI tools\nconst tools = await client.listTools();\nconst response = await claude.complete({\n prompt: 'What is the main topic of example.com?',\n tools: tools\n});\n```\n\n## Development\n\n```bash\n# Clone the repository\ngit clone https://github.com/webscraping-ai/webscraping-ai-mcp-server.git\ncd webscraping-ai-mcp-server\n\n# Install dependencies\nnpm install\n\n# Run tests\nnpm test\n\n# Add your .env file\ncp .env.example .env\n\n# Start the inspector\nnpx @modelcontextprotocol/inspector node src/index.js\n```\n\n### Contributing\n\n1.
