> That is a factual statement,

I think most people, even most devs, don't actually know how crappy an MCP client is built, and that it's essentially an MITM approach and that the client sends the LLM on the other end a crappy pretext of what tools are mounted and how to call their methods in a JSON, and then tries to intelligently guess what response was a tool call.

And that intelligent guess is where it gets interesting for pentesting, because you cannot guess anything failsafe.
