Welcome to AgentDojo
What this site is, what you will learn, and how to use it.
Welcome! AgentDojo is a free, hands-on learning site for the modern AI-coding stack. If W3Schools taught you HTML, this is where you learn to drive Claude Code, Codex, Gemini CLI, Cursor and the Model Context Protocol.
What you'll learn
- Platforms — install and use the major AI coding tools, from terminal agents to full editors.
- MCP — connect assistants to files, databases, browsers and APIs.
- Agentic coding — how autonomous coding agents actually work, and how to keep them safe and effective.
- Prompting — the patterns that turn a vague request into reliable code.
How to use this site
- Read a lesson. Each one is short and example-driven.
- Try it — open the Playground to run code, validate MCP configs, or drive a simulated agent terminal.
- Practice — every section has exercises with instant feedback. Your progress is saved in your browser.
Before you start
You'll get the most out of this if you know basic programming (any language) and can open a terminal. You do not need a GPU, and most lessons need nothing more than an API key or a free local model.
Tip: Bookmark the [Playground](playground.php) — you'll come back to it often.
