This video tutorial explores Google's A2A (Agent-to-Agent) Protocol, which standardizes communication between AI agents similar to how MCP standardizes remote tool calling. Learn about the A2A protocol's design principles and implementation through Chris Hay's a2a-cli tool. Discover how to build and host your own agent using ADK (Agent Development Kit) with practical demonstrations. The tutorial covers key components including agent capabilities, tasks, artifacts, and provides a step-by-step guide to creating an agent with A2A-Server. Access the GitHub repositories for a2a-cli, a2a-server, and a2a-agent-record to follow along and implement your own agent communication systems.
