Auto XP
Auto XP is a Fabric mod that repeatedly throws Bottles o' Enchanting so that a damaged item with Mending gets repaired without manual work.
What it does
Holding one key starts the throwing routine. The mod looks for Bottles o' Enchanting anywhere in the inventory, moves one into the hotbar, and throws it at a configurable pace until the repair is complete, then stops on its own. Once the gear is repaired, or the player runs out of bottles, a message is shown and the routine ends.
The mod is a client-side Fabric mod for Minecraft 1.21.9 – 1.21.11, so only the player's game needs it, and no server installation is needed. It requires Fabric API and Java 21, and it works with Fabric Loader 0.16 or newer. Once the routine ends, the original hotbar slot is restored when the key is released, and the mod throws from the main hand or the off hand. Auto XP is published under All rights reserved and is not open source.
Key features
Hold-to-throw key
A single key held down runs the throwing routine, so the player does not need to click for each bottle.
Automatic stop
Throwing stops once the item is fully repaired or no bottles remain, and a message reports the stop.
Configurable pace
The rate at which bottles are thrown can be set in the mod's options.
Hotbar restore
The selected hotbar slot returns to its original position when the key is released.
