remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Integrations

  • Enables custom JavaScript execution on target web pages, including headless Chrome/Chromium rendering and the ability to run custom JS scripts with configurable timeout settings.

WebScraping.AI MCP Server

A Model Context Protocol (MCP) server implementation that integrates with WebScraping.AI for web data extraction capabilities.

Features

  • Question answering about web page content
  • Structured data extraction from web pages
  • HTML content retrieval with JavaScript rendering
  • Plain text extraction from web pages
  • CSS selector-based content extraction
  • Multiple proxy types (datacenter, residential) with country selection
  • JavaScript rendering using headless Chrome/Chromium
  • Concurrent request management with rate limiting
  • Custom JavaScript execution on target pages
  • Device emulation (desktop, mobile, tablet)
  • Account usage monitoring

Installation

Running with npx

env WEBSCRAPING_AI_API_KEY=your_api_key npx -y webscraping-ai-mcp

Manual Installation

# Clone the repository git clone https://github.com/webscraping-ai/webscraping-ai-mcp-server.git cd webscraping-ai-mcp-server # Install dependencies npm install # Run npm start

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" } } } }
  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.

Running on Claude Desktop

Add this to your claude_desktop_config.json:

{ "mcpServers": { "mcp-server-webscraping-ai": { "command": "npx", "args": ["-y", "webscraping-ai-mcp"], "env": { "WEBSCRAPING_AI_API_KEY": "YOUR_API_KEY_HERE", "WEBSCRAPING_AI_CONCURRENCY_LIMIT": "5" } } } }

Configuration

Environment Variables

Integration with LLMs

This server implements the Model Context Protocol, making it compatible with any MCP-enabled LLM platforms. You can configure your LLM to use these tools for web scraping tasks.

Example: Configuring Claude with MCP

const { Claude } = require('@anthropic-ai/sdk'); const { Client } = require('@modelcontextprotocol/sdk/client/index.js'); const { StdioClientTransport } = require('@modelcontextprotocol/sdk/client/stdio.js'); const claude = new Claude({ apiKey: process.env.ANTHROPIC_API_KEY }); const transport = new StdioClientTransport({ command: 'npx', args: ['-y', 'webscraping-ai-mcp'], env: { WEBSCRAPING_AI_API_KEY: 'your-api-key' } }); const client = new Client({ name: 'claude-client', version: '1.0.0' }); await client.connect(transport); // Now you can use Claude with WebScraping.AI tools const tools = await client.listTools(); const response = await claude.complete({ prompt: 'What is the main topic of example.com?', tools: tools });
