Let me begin by addressing a common concern regarding whether AI agents are simply superior to MCP. Comparing an AI agent to MCP is like comparing the brain to the nervous system. When customer traffic peaks, every store’s agent independently reaches the same smart conclusion: reroute customer overflow to the healthiest route and/or exit. While MCP handles the agent’s reach across the network, A2A handles its communication with its peers. This time, one store’s agent feels the pressure and sends a message to the network: “Can anyone absorb my overflow for a few minutes?”
