InvUtils
by P1x3lc0w
InvUtils is a Fabric client-side utility that swaps items in the player's inventory with a single key press, for tools, armor and the main hand.
What it does
Per the author notes, the mod works on the client alone, so only the player running the game needs it. It handles inventory swaps: it can put the item suited to the block under the crosshair into the main hand, exchange a chestplate with an Elytra, and switch a tool to a non-Silk Touch version when needed. Players bind these actions to keys, and the swaps happen without opening menus.
InvUtils requires Fabric Language Kotlin, and it can use Cloth Config API and Mod Menu for its settings screen. The license is GNU General Public License v3.0 only, and the source code and issue tracker are public. Builds cover 1.19 – 26.3 with 16 release versions, and the latest Fabric file is 1.5.4+mc26.3 for 26.3, published on 2026-09-18. The first release came out on 2022-12-19.
Key features
Tool swap for focused blocks
The main hand item can be replaced with the tool that suits the block the player is looking at.
Chestplate and Elytra swap
The chestplate slot can be exchanged with an Elytra, so a player can switch between armor and flight without digging through the inventory.
Silk Touch switching
A tool can be swapped to a version without Silk Touch, or the reverse, for mining that needs the enchantment or leaves it out.
Key-driven actions
Each swap is triggered by a key, so the actions run from the keyboard while the game is in play.

Who it’s for: Players on Fabric who want fast inventory changes during play. Only the client needs the mod, so it can be added to a single-player or multiplayer client without server installation.
