That only applies if you are talking about a well established recurrent workflow. That's not how MCPs are used to begin with.

It's easier if you started a while back shunning all human labor (including your own) in favor of fully deterministic systems. Reality is deterministic so your company or project logically can be run off a single compiled binary with formal verification of correctness for every possible scenario.
