CommandsMC mod -
Stop guessing what a command does. Just start typing it.

CommandsMC mod is a lightweight, client-side Fabric mod that explains Minecraft commands while you type them. Open the chat, type a command, and a clean tip card appears in the top-left corner showing exactly what it does, its syntax, and a real example. No hovering, no tabbing out to a wiki, no memorizing arguments.

It is powered by commandsmc.online and uses the same on-brand styling, so the in-game card looks just like the website.

Why you'll want it

Live as you type. The card updates with every keystroke. Type /eff and it already knows you mean /effect.
Argument-aware help. Once you're past the command name, the card highlights the exact argument your cursor is on and explains that part. After /give @s it shows what goes in the item slot.
Color-coded syntax. Targets, coordinates, literals, and optional arguments are each colored, so a long command is easy to read at a glance.
Smart matching. Prefixes and aliases just work: /w finds /msg, /tm finds /teammsg, /? finds /help.
The full vanilla command set. 83 commands covered, from beginner staples like /give and /tp to advanced tools like /execute, /scoreboard, and /data.
One key to toggle. Press F6 to turn the tips on or off, in-game or with chat open.
Perfect for

Players learning commands for the first time
Map makers and datapack creators who live in /execute and /scoreboard
Server admins reaching for /ban, /whitelist, and /gamerule
Anyone tired of alt-tabbing to look up syntax
