How to Build AI Agents — Free Video Roadmap
A step-by-step path through the best free YouTube videos on building AI agents — from the core ideas, to tool use with MCP, to hands-on framework courses, orchestration, and shipping to production. Built from 11 agent frameworks and 30 hand-sequenced videos.
To learn to build AI agents in 2026, follow this order: understand the agent loop, add tool use with the Model Context Protocol (MCP), build hands-on with a framework like LangGraph or CrewAI, then add orchestration and memory and ship to production. This roadmap sequences 30 of the best free YouTube videos — beginning with "LangChain Explained in 13 Minutes | QuickStart Tutorial for Beginners" by Rabbitmetrics (1,127,407 views).
