Why MCP can't be as simple as Naive Context Protocol

Since the introduction of Model Context Protocol, I've been wondering why this protocol is so complicated to work with and after many wasted hours and a few MCP spec updates, I've decided to write down what I think MCP should have been and I call it Naive Context Protocol ¯\_(ツ)_/¯.

Maybe this approach is in fact naive (please tell why!), the "spec" is very minimal at this point (I will expand based on feedback here) and it probably ignores some use-case (some of them on purpose), but I would like to hear:

1. What everyone here thinks the MCP/NCP should've been/should be?

2. What use-cases would you like a context protocol to support?
