Keybind break fixer

This mod resolves a Minecraft issue in which binding the Attack/Destroy action to any key other than left or right click incorrectly triggers anticheat…

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

⬇ Download for 26.2⬇ Download for 26.1.1–26.1.2
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This Minecraft mod fixes a long-standing compatibility problem between custom keybinds and server-side anticheat systems.

By default, Minecraft uses left click for attacking and right click for interacting or placing blocks. But many PvP players remap the Attack/Destroy action to other mouse buttons or keyboard keys. The issue is that some anticheat plugins don’t handle these remapped inputs correctly and can mistake them for FastBreak or other suspicious behavior.

The mod resolves this by making sure all valid inputs for the Attack/Destroy action are recognized the same way the game would handle default controls. It keeps input timing consistent with vanilla behavior so that remapped controls don’t create unusual packet patterns that could be misinterpreted by anticheat systems.

In practice, this means players using custom keybinds, accessibility tools, or alternative setups get a more reliable experience without being falsely flagged.
