It isn't hard to see why. I had a really hard time wrapping my head around why MCP was necessary and useful but I tried using* one recently and it's remarkable how big the gap between just being able to reply and being able to interact is.
*after forking and modifying it for my use case
yeah current AIs are surprisingly good at figuring out which tools to call and how to call them!
I'm curious to hear which one you forked and found useful? I've looked at the awesome MCP list but was a bit struck by decision paralysis when trying to figure out what to try, so I ended up just not trying any.
