About this project

What does Auto Librarian add?

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 (K by default).
Start and stop the loop with a single key (J by default) or by .al chat commands.
28 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.

How It Works

Press K to open the selection screen. Toggle the enchantments you want — green ✓ means selected. Close the screen.
Stand within ~3 blocks of a librarian villager and its lectern. An axe in your hotbar is recommended.
Press J to start (or use .al <enchantment> in chat). The mod will
- Find the nearest librarian within 5 blocks.
- Open its trade list and read the offered enchanted book.
- Compare the book's enchantment against your selection.
- If it's a match → stop, play the sound, and announce the find.
- If not → break the lectern, wait for the drop to be picked up, place the lectern back, check trades again.
- Repeat until a match is found or you press J again to stop.
