MCP is eating the world

I'm still getting the hang of this but Apple's Foundation Models framework [1] (the one recently announced in WWDC) follows this protocol, correct? Does this mean that MCP, as a protocol, can actually take on different forms depending on how platforms/OSes want to allow their users to integrate with LLMs?

Apple’s Foundation Models support “tool calling”, but that is not MCP. It is a different approach that those interested in MCP should check out, via Swift protocols and macros. Notably I think the structured Swift marshalling is cool. An understated part of WWDC this year.
