MCP Explained — Model Context Protocol for AI Agents | Architecture, Security & Ecosystem

AI agents can reason, but they cannot reach your tools, files, or data. Model Context Protocol (MCP) fixes that. Created by Anthropic and now governed by the Linux Foundation, MCP is the open standard connecting every AI agent to every tool — the USB-C for AI. This tutorial covers the full architecture, all six primitives, how to build a server in five lines, the security research every team needs to see, and the 10,000-server ecosystem. 30 scenes, zero fluff.
