A2A: Agent-to-Agent protocol

15 min applied30 min research3 curated resources

Learn the difference: MCP connects an agent to tools; A2A connects agents to other agents, even when built by different teams or frameworks. Each agent publishes an 'Agent Card' (who it is, what skills it has, how to call it). Expose your help agent as an A2A service and call it from the supervisor.

Builds on: Module 3 · Project 2: Company Tools as an MCP Server (Model Context Protocol)
