MCP Explained Simply — How AI Finally Connects to Real Tools (Every Engineer Must Know)

The smartest AI on the planet still can't check your Kubernetes cluster, roll back a deployment, or raise an incident ticket — on its own. In this video I explain MCP (the Model Context Protocol), the open standard from Anthropic that finally lets AI connect to your real tools, data, and systems. No jargon, no messy live demo — just a simple monitoring analogy and a clear, step-by-step walkthrough any engineer can follow. If HTTP standardised the web and USB-C standardised our chargers, MCP is doing the same thing for AI. Learn how it works, why it beats old-style API integrations, and how to avoid the mistakes engineers make when they build their own MCP server. 🔔 Day 20 of the 30-Day AI Series.
