I recently started learning MCP (Model Context Protocol), introduced by Anthropic, and it gave me a clear view of how AI actually works with real systems.
At a basic level, the flow is simple:
AI (inside a Host app) → MCP Client → MCP Server → Tools/Data.
The client acts as a bridge, the server exposes tools, and the host is where AI lives. Instead of guessing, AI can now fetch real data and perform actions.
It’s a small concept, but it opens the door to building real AI-powered systems.
