Wasn't the point of REST supposed to be runtime discoverability though? Of course REST in practice just seems to be json-rpc without the easy discoverability which seems to have been bolted on with Swagger or whatnot. But what does MCP do that (properly implemented) REST can't?

Half the point of MCP is just making it easy for an LLM to use some language in a standard way to talk to some other tool. I mean MCP is partly a standard schema for tools to interact and discover each other, and part of it is just allowing non-webserver based communication (like stdio piping, especially useful since initial the use case is running local scripts

That's so wrong. REST in practice is more like HTTP with JSON payloads. If you find anything similar to json-rpc calling itself REST just please ask them politely to stop doing that.
