You linked to one part of the spec and just wanted to ignore everything else? That's fine, but then you wouldn't be obeying the standard and wouldn't be an "MCP."
So, are you agreeing with me?
Respectfully I think I've engaged with you before and you just seem generally confused about nuanced concepts.
I'm open mindedly hoping you'll be more specific in what about the protocol you find problematic?
The base protocol is just JSON-RPC, and then you have to implement initialize. Everything else is optional.
