It's literally JSON-RPC I'm not sure why you say it's a REST API. It's not even close to a REST API.

In this context/application I see a lot of similarities.

They both provide stateless RPC methods and human readable metadata that makes them easy to route.

You could ask why json-rpc was even necessary for 2.0. I think mostly just for stdio and backwards compatibility.

In the venn diagram of MCP and REST, there is an (optional) overlap for sure but one does not subsume the other.

REST is explicitly not RPC.
