AutoLibrarian is a lightweight automation mod that takes the tedium out of librarian villager trading. Instead of manually breaking and replacing lecterns for 20–40 minutes to reroll a single enchanted-book trade, AutoLibrarian handles the entire process for you — fast, reliably, and with no commands or config files.
Main Features
- Automatically rerolls a librarian's enchanted-book trade until one of your selected enchantments appears.
- Pick enchantments on a selection screen with a MAX. PRICE of your choice (K by default).
- Start and stop the loop with a single key (J by default) or by .al chat commands.
- 31 supported enchantments, including Mending, Unbreaking III, Efficiency V, and more. (SEE THE FULL LIST DOWN BELOW)
- Plays a soundeffect and announces the find on the action bar when a match is found, then stops automatically.
- Breaks the librarian's own lectern, picks up the drop, and places it back. No spare lecterns required.
- Auto-swaps to an axe (if one is in your hotbar) while breaking, then swaps back to your previous slot.
- Client-side only — works on any server, no server-side install required.
