No, it really matters because of the impact it has on context tokens. Reading on GH issue with MCP burns 54k tokens just to load the spec. If you use several MCPs it adds up really fast.
I do think that we should adopt Amp's MCPs-on-skills model that I've mentioned in my original comment more (hence allowing on-demand context management).
Even if the model doesn’t already know the cli commands it can interrogate them at a much lower token cost for just the commands needed.
Eventually I hope that models themselves become smarter and don't save the whole 54k tokens in their context window
