It would, but the point of MCP is that it's discoverable by an AI. You can just go change it and it'll know how to use it immediately
If you go and change the parameters of a REST API, you need to modify every client that connects to it or they'll just plain not work. (Or you'll have a mess of legacy endpoints in your API)
Not a fan, I like the "give an LLM a virtual environment and let it code stuff" approach, but MCP is here to stay as far as I can see.
