This tutorial guides you through Google's new Agent Developer Kit (ADK), the standard for effortless coding of AI agents across all models, companies, and platforms. Learn how ADK works with MCP servers, Crew.ai, LangGraph, and OpenAPI applications. Follow along as the instructor explores the ADK manual, detailed workflow instructions, and numerous code examples for building AI agents with specialized tools, multi-agent configurations, dynamic memory, and state-dependent logic. Discover how to code more intelligent tools and manage multi-agent protocols using Agent2Agent, Google's open-source protocol. Based on work by Erwin Huizenga (Machine Learning Lead) and Bo Yang (Software Engineer) from Google for Developers.
