Just the normal tools, that is no MB special tools are needed. I think there might have been bolts that took a 20 or 21mm socket but I might be wrong on that. I also recall using a torx head socket maybe #40. If you have a good set of 1/2" drive metric sockets and torx head sockets you should be covered.

I do remember having trouble getting the piston to go back into the caliper, not enough arm strength on my part, so I used a large C clamp and had no problem.
