On Join Commands

On Join Commands is a lightweight Fabric client-side mod that automatically executes configured commands whenever you join a Minecraft world or server.

Brief overview:

With this mod you can apply commands on world or server join without manually typing them.

For example:

• Server commands: if you want for a weather to be always clear when you join, you can type server:/weather clear in .cfg file. If you write server:/say Hello, then you will send message Hello in chat everytime you enter a world/server;
• Client commands: you can automatically execute Fabric client-side commands registered by other mods. How it works: this Fabric mod: https://www.curseforge.com/minecraft/mc-mods/skin-changer uses /skinc client-side commands to change a player's skin, but you have to reapply them every time you open Minecraft. If you write client:/skinc file *your local file path* in On Join Command's config file, then you will always load your skin from a local directory automatically.
