What if you don't need MCP at all?

Yeah, "MCP" felt like BS from jump. Basically it's the problem that will always be a problem, namely "AI stuff is non-deterministic."

If there was some certainty MCP could add to this equation that would perhaps be theoretically nice, but otherwise it's just .. parsing, a perhaps not "solved" problem, but one for which there's already ample solutions.

Why are they nondeterministic? You can use a fixed seed or temperature=0.

The whole point of "agentic AI" is that you don't have to rigorously test every potential interaction, which means that even a temperature zero model may behave unexpectedly, which is bad for security.

Even with zero temperature (and some of the latest models don’t allow that) you’re still not absolutely guaranteed deterministic output.

Just repeatable output.

What does deterministic mean in this case?

Right, I'm using a perhaps loose definition of deterministic here, as in -- "With AI tools, you cannot 100% predict any output based on input, the way you can with most programming."

It's also kind of an impossible request given that AI tools are for generic unpredictable input.
