You realize that not every user of agents uses them like Claude or Codex on your local CLI right? MCP is the standard for cloud agents. How do you get a cloud agent working in an ephemeral container access to skills? The answer is MCP.

A 'skill' is generic concept - as short set of right-sized instructions for a given cli or api call, it can be applied in any context.

If MCP did not exist today, we wold not invent it.

We'd probably hormonize in basic conventions around json calls, and not much more.

The rest would just be api use / instructions.

LLMS to day are exceedingly good at calling RESTful APIs, the MCP standard provides little advantage.

The advantage of 'skills' is that they are more generic - an Enterprise LLM can evoke 'capabilities' which may or may not involved rpc type calls, and if they do, there will be varying level of instructions provided.

There's almost not point to MCP.

Yea so your answer is to build something that’s like MCP basically. You’d standardize conventions around json, great, now standardize auth. Oauth is nice right? That’s MCP. MCP is literally a restful API using JSON with OAuth.

You’re arguing against MCP but have nothing to offer that isn’t nearly the same thing.

Agreed, not sure what people arguing against MCP are even arguing against. The only valid critique of MCP is that you think the RPC protocol isn't ideal, sure, you could argue about the protocol design, for example I wish there was better support for stateless calls. But why wouldn't you want a protocol for back-end API calls? Otherwise you need custom clients for each possible backend you want to invoke.
