iammojogo's Auto Switch Tool
by iammojogo
iammojogo's Auto Switch Tool changes the hotbar slot automatically, so a player who mines or fights never has to pick the right tool by hand.
What it does
When a block is broken, the mod selects the tool in the hotbar that mines it fastest. When a hostile mob is attacked, it selects a sword instead. The whole inventory is checked, not only the hotbar, and the chosen tool is moved into the hotbar as needed. Damaged tools are preferred so that their remaining durability gets used up before fresh ones are touched. Axes are left out of combat switching, which keeps weapon choice closer to ordinary play.
The mod works in single-player and on multiplayer servers, but only the client needs it, so players can join a server without installing anything. It is published for Fabric, Forge and NeoForge, and the files cover game versions 1.12.2 and 1.21.11. The latest build, 1.2.0 for 1.21.11, was released on 2026-08-20. The code is released under the MIT License, which allows free use, modification and redistribution, though the project is not open source.
Key features
Automatic tool for blocks
Breaking a block selects the hotbar tool that mines it most quickly, without any key press.
Sword for hostile mobs
Attacking a hostile mob switches to a sword from the inventory, so combat needs no manual swap.
Whole-inventory search
The mod looks through the entire inventory and the hotbar when it picks a tool, not just the current slots.
Damaged tools first
Partly worn tools are chosen before undamaged ones, so durability is used up in a steady order.

Use cases
Who it’s for: Players who want fewer hotbar changes during mining and combat, in single-player or on a server that they join without any server-side install.
