My Aldi compressor, which is the same as those Mean Mother ones, just has the clip on chuck and it keeps pumping away until I look at the gauge. One could be made to fit inline from the chuck to the valve using a pressure relief valve so it just releases the air from the compressor but you'd need to put a one way valve in aswell so the air doesn't come back out once the pressure is reached. Could be made pretty easily. Is it worth your while though?
Hmm, I think I have most of the parts here to make something. I might have to look into this now...
Lol
If you want to go "auto" for the vast majority of 12 volt jobbies then you will need an adjustable pressure regulator and switch.
The reg will have to be adjustable so you can set what pressure to inflate the tyre.
The switch will be to turn off the Compressor.
If you don't have that the compressor will just run it's guts out while you are dicking around elsewhere and not needed and either overheat or exceed it's duty cycle.

The reg is easy but the switch set up would be tricky
