01 / Plain-language context

How MCP (Model Context Protocol) works.

MCP standardizes how AI applications connect to the world. Instead of building custom integrations for every tool, MCP provides a single protocol. An MCP server exposes tools (functions the AI can call), resources (data the AI can read), and prompts (templates). MCP clients (like Claude Code, Cursor, or your custom app) connect to these servers. Think of it as "USB for AI" - one standard connector for everything.
