I think there's going to be a lot of places where you want the middleare that's only exposing a sub-set of apis. and the Ideas that you copy some URL, put it in your LLM Client, and then it magically gets all the tools/endpoints available to you, and you start interacting with it, simplifies the process greatly for a lot of users. No swagger, no http post, body vs params, etc....just play with with your prompt sentance until you get it to do what you want.

(edit: sorry, I responded to wrong thread.)

> LLM Can call tools without MCP 100% fine.

but can the LLM host UI ask me for permission (in an outside-of-LLM domain) if the LLM wants to call API foo.bar ?
