Join Allen Firstenberg and Noble Ackerson in a deep dive into the evolving world of AI agent protocols. In this episode of Two Voice Devs, they unpack the Agent-to-Agent (A2A) protocol, comparing it with the Model Context Protocol (MCP). They explore the fundamental differences, from A2A's conversational, stateful nature to MCP's function-call-like structure. The discussion also touches on the new Agent Payment Protocol (AP2) and its potential to revolutionize how AI agents interact and transact. Is A2A the key to unlocking a future of autonomous, ambient AI? Tune in to find out!
