Lets say MCP is used for 100% of the ecosystem's need of tool calling, who exactly is earning the money for that usage?

Based on the earnings statements thus far this year if the question is "who is making money" the answer is "NVIDIA". It passes through other hands first sometimes, but at 75-85% net earnings for over a year or whatever, it's pretty much all going to the same place.

MCP that you pay $10.00 a month too and it enables an LLM to do all your Amazon shopping with ease? This is far out, and I'm not convinced it will be MCP that corners this.
