I appreciate the take. I can certainly see your position.

In my mind what we are doing is building a common place to evolve the pattern. I wouldn’t really call it “standardize”, since in the end in this space adoption matters. (Writing a standard is worth nothing if nobody is using it). I expect MCP apps to evolve and iterate independent from the main spec for a while. You are right, it’s early and premature to say “this is done”. That’s the goal with extensions.

I do believe that I rather have commonalities between a Claude.ai and a ChatGPT as a developer (not sure that’s true if I was mostly looking at it from a product perspective). I also think you will see chat providers iterate on top of it, and mcp apps is more a common core than the full thing one can use on every platform.
