LiveBuddy

Every Buddy carries a name of its own, its own settings and a distinct skin, and several Buddies can be active together. A Buddy works in one of three operational modes: it stays close to the player, it stays in one place and sleeps at night, or it works as an autonomous workhorse that carries out assigned tasks. Buddies move with vanilla pathfinding, open doors, swim through water and cross uneven terrain. When night falls, a Buddy looks for a bed near its registered home position and rests there.

The mod is aimed at players who want help with resource gathering, since tasks such as chopping, farming, grading, carving and torch placement run without tools or consumables. Combat damage is fixed at the equivalent of an iron sword, and tools never lose durability. A Buddy holds 27 storage slots reserved for it, and whatever it gathers while working goes into them without manual sorting; once more than 18 of those slots are occupied, the Buddy heads to a chest close by and empties its load into it. A server running it needs every connecting player to have it too. LiveBuddy has no required dependencies, though its notes say that spawning many Buddies needs a capable setup.
