The MCP announcement had me excited on day one. Compared to that, this is a miss for me. The capabilities it provides seem to be no more than a system prompt, which was already a mostly solved problem.
What “agents” need is not a protocol for operating, they need a protocol for discovery and addressability. How do I find someone’s agent? How do I talk to it and verify its identity? Once I’ve done that, it can just be a normal chat interface for all I care.
An endpoint implementing this protocol would describe the agent and its capabilities, including examples. So I guess you could index that and create a discovery service.
