Interesting points. A couple of questions. Do you have a frontend (React, Vue, anything) and if you do, does it interact with the server using the MCP server or the JSON API? Are all your clients AIs or do you expect that most of them will be AIs?
The reason I'm asking those questions is that a customer of mine has a service with a JSON API, a Vue frontend and a score of customers using that JSON API. We know that the newest ones are using bots to code their clients (and they are using them wrong, by the mistakes they do.) I don't see a near future in which all those third party apps become LLMs that would benefit from a MCP server and we retire the API.
I do have a front-end, but it interacts with the server with a specific, private API. It's using a more compact data encoding than JSON optimised for streaming the data that's needed for the front-end.
But yes I agree with your point: for a simpler app with a more traditional web UI it's likely the API used by the front-end would largely overlap with the user-oriented API. Then indeed the REST API has to be maintained for as long as humans continue to use the front-end.
