How do I install Force Lowercase Commands?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

The listing gives Minecraft 1.20.5, 1.20.6, 1.21, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

Force Lowercase Commands

fabric forge

Forces Minecraft client to use lowercase letters in commands.

After Minecraft 1.19.1 update, Bukkit changed player commands to be handled with Minecraft's command system which means that commands added by plugins can no longer be used case-insensitively on servers such as Bukkit, Spigot, Paper, Purpur, or other forks. This mod works around that change clientside by lowercasing command when sending.

I find this useful when trying to type commands fast, but the caps lock is on or I accidentally started typing a command with an uppercase letter.

How does it work?

When sending a command in chat this mod replaces uppercase letters in the command with lowercase letters. If the command has arguments, those won't be touched by this mod.

Example behavior of this mod:

The command you typed in chat --> How this mod changes it

/SPAWN --> /spawn

/Spawn --> /spawn

/HELP SPAWN --> /help SPAWN

/Help SPawn --> /help SPawn
