Giao thức A2A

In the world of AI, one thing is clear: the future won’t be powered by a single agent. It will be powered by many agents working together — reasoning, delegating, and collaborating. But here’s the catch: without a shared language, agents can’t truly communicate.

That’s where A2A (Agent-to-Agent Protocol) comes in.

This course is your complete introduction to A2A — a standardized protocol that allows agents to share information, delegate tasks, and collaborate seamlessly, regardless of who built them or what tools they use.

Think of A2A as the “Internet Protocol” for AI agents — a foundation that makes interoperability possible. If you want to understand the future of AI systems and learn how to actually build agents that talk to each other, this course is for you.

By the end of this course, you’ll not only understand the design principles behind A2A, but also build, run, and interact with your own A2A-enabled agents.

What You’ll Learn

• Understand the fundamentals of the Agent-to-Agent (A2A) Protocol.

• Learn how Agent Cards & Skills define agent identity and capabilities.

• Explore how A2A connects with MCP (Agents  <-> Tools vs Agents <-> Agents).

• Build your own Agent Executor — the brain that powers agent logic.

• Start and run an A2A Server to bring agents to life.

• Interact with agents using the A2AClient (streaming & non-streaming requests).

• Master both the theoretical foundations and hands-on coding practices of agent collaboration.

Who This Course Is For

• Developers & AI enthusiasts who want to build interoperable agents.

• Researchers curious about multi-agent communication standards.

• Tech professionals exploring AI protocols and infrastructure.

• Anyone interested in the next frontier of AI collaboration.

Requirements

• Basic programming knowledge (Python preferred).

• Familiarity with AI/ML concepts helps, but not required.

• Curiosity about how agents collaborate in real-world systems.
