Tutorial on extending MCP/A2A agents, cutting-edge agent orchestration.
Summary
A tutorial extends a currency agent built on Google's A2A (Agent2Agent) and MCP protocols with A2UI, enabling real-time streaming of interactive UI components like charts and approval forms. The agent uses the ADK framework (Python, Go, Java support) and Antigravity CLI, the Gemini CLI successor, requiring a Google Cloud project with gemini-2.5-flash and ADK 2.1.0. It demonstrates multi-agent interoperability with dynamic UIs, using A2A for agent communication and A2UI for custom frontends.
