Minecraft Cobblestone Generator Bot?

I'm looking for a Minecraft Bot, which I then just place in a Cobblestone generator and it automatically degrades for me Cobblestone but unfortunately I find nowhere in the net such a simple Bot:

hope for your help

You can make obsi behind the cobbl and just put a heavy object on your mouse then he dismantles it and because of the obsi does not happen that you accidentally dismantle something else

I would also like to activate it while I'm working on my pc
