Why don’t they just own a REST or RPC server? This is the part of the MCP motivation I’m not totally getting. In fact, you can prove to yourself that your LLM can hook into almost any existing REST api in a few minutes, which gives it more existing options and functionality than just about anything else as it stands now.

Things like swagger or graphql already provide you discovery.

Would it help you to know that the original use case of MCP was communicating information about and facilitating communication with servers that the LLM frontend would run locally and communicate with over stdio, and that remains an important use case?
