Auto Villager (Librarian) Reroll
Auto Villager (Librarian) Reroll repeatedly replaces a librarian's lectern until a chosen enchanted book appears among the villager's trades.
What it does
The mod automates librarian lectern rerolls. A player lists the enchanted books wanted, sets the highest emerald price they will pay for each one, and starts the process by right-clicking a lectern. The mod breaks and replaces the lectern, then checks the villager's offers, and keeps going until a match appears or the player presses Stop in the GUI. An optional setting can lock the trade once a match is found, so it is not rerolled away.
Controls for the mod are found under Options, Controls and Miscellaneous, where the Open Villager Reroll hotkey can be rebound. The mod is client-side only, so it changes nothing on a server and multiplayer players need nothing extra. It runs on Fabric for 26.1 – 26.2 and is released under the MIT License. The source code and issue tracker are public, and the first release came out on 2026-05-19.

How it compares
Villager trade-trade runs on the server only, with files for 26.2 – 26.3 under the MIT License, and it is not open source. Start Reroll is open source under the MIT License and needs both client and server, with files for 26.1.2 – 26.2. Librarian Trade Finder is client-side only, open source under the GNU General Public License v3.0 only and covers 1.19.2 – 26.1.2. Each of these differs in its version range or environment, so pick by the game version in use.
