The Complete Guide to MCP Web Scraping: Everything Developers Need to Know

The Model Context Protocol (MCP) has fundamentally changed how AI assistants interact with the web. This comprehensive guide covers everything developers need to know about MCP web scraping - from foundational concepts to advanced techniques.

Part 1: Understanding MCP

What is the Model Context Protocol?

MCP (Model Context Protocol) is an open standard developed by Anthropic that allows AI assistants like Claude to connect to external tools and data sources. Think of it as a universal adapter that lets AI models use specialized tools.

Why MCP Matters for Web Scraping

Before MCP, AI assistants couldn't reliably access web data:

MCP solves these by providing:

• Standardized interface - One protocol for all tools
• Real-time data - Fresh information from any source
• Tool composability - Combine multiple tools seamlessly
• Security model - Controlled access to external resources

How MCP Works

MCP uses a client-server architecture with JSON-RPC:

1. Server Discovery

2. Tool Registration

3. Tool Invocation

4. Response
