The Mod replaces the vanilla ankylosaurus with a new version that can autoharvest resources if it is close enough, just like the doedicorus.
I tested it in Singleplayer and it can harvest fast and quite reliable till it hits 50% weight. This Mod is not overpowered IMO but makes it for
soloplayer on the server less of a chore to farm metal, while the doufarm-method is still much better.

Might be worth thinking about it.
