MCP for Beginners: Build, Connect & Debug MCP Servers

About this course

This course contains the use of artificial intelligence.

Your AI assistant is clever, but on its own it can't see your files, your repository or your data. MCP changes that.

The Model Context Protocol (MCP) is an open standard that lets AI applications connect to tools, data and services in one consistent way. Claude, ChatGPT, Cursor, VS Code and many other apps already support it. Build an MCP server once, and every one of those apps can use it.

This course takes you from "what is MCP?

" to a working MCP server of your own in under an hour. There are no long protocol lectures. You follow one small online shop, ShopLite, through every lesson: you read its project files, query its sales database, check its GitHub issues and finally build its business tools yourself.

What makes this course different

Real demonstrations, not mock-ups. Every AI conversation you see on screen was recorded against a live MCP server: the official filesystem and GitHub servers, OpenAI's documentation server, a SQLite database and the server you build.

Current tooling. The code uses the stable MCP TypeScript SDK v2, which implements the 2026-07-28 MCP specification, and MCP Inspector 2.9.

Safety built in from the start. You'll see a server refuse a file outside its folder, a database server reject a DELETE, and the difference between GitHub's full toolset and its read-only endpoint.

Real-world troubleshooting. A whole lesson on two problems teams actually hit with MCP over SSE: the "changing port" that turns out to be normal, and the stream that keeps closing, with a diagnostic matrix and a heartbeat fix."

Pause and predict" moments in most lessons, to check you've understood before the answer appears.
