This mod adds damage from the stonecutter to the player if they are standing on it, and it works on any type of mob.

This mod allows you to kill groups of identical mobs with a single blow. Hold down the ~ (tilde) key (this can be changed in the control settings) and hit any mob – all mobs of the same type within a 2-block radius will receive the same damage.

GroundCheck is a simple client-side mod that warns you when you're about to break the block you're standing on - preventing accidental falls.
