What's all the fuss about Model Context Protocol?

Agreed. This is an overblown explanation of a protocol for API communication between agents. Nothing more.

It could be useful if setup in a way that works for you on both ends. And we all know how likely that is with anyone else's API. Also, if you use MCP, you will be the one setting up your tool calls to use that protocol, when you could do them directly any way you want to. It's extra scaffolding that's not always an advantage by itself.
