Server Creative Killer (Fabric)

Server Creative Killer — a lightweight, exclusively server-side mod for Minecraft 1.21.11 and 26.3 that adds a precision administration tool. It allows server operators to instantly eliminate troublemakers or test game mechanics while completely ignoring Creative Mode, immortality effects, and third-party modifications.

Since the mod operates on the server side (Server-side only), players don't need to download anything — they can join the server from a completely vanilla client.

🚀 Key Features

• Full Creative Mode Bypass: Standard Minecraft damage ignores players in Creative. This mod bypasses this limitation at the server packet level.
• Ignoring Immortality Mods: Instead of dealing standard damage, the code uses a hard entity removal method (discard()), which prevents totems, custom armor, or third-party "absolute invulnerability" effects from triggering.
• Safety for Regular Players: The elimination weapon works strictly in the hands of server operators (OP) with permission level 2 or higher. A regular player, even if they somehow obtain this item, will not be able to activate its property.
• Vanilla Compatibility: The mod does not register new items in the game registry, which eliminates client crashes. The logic is tied to a regular Netherite Sword with a specific name component.

🛠 Installation and Usage

1. Compile the project using the command ./gradlew clean build.
2. Place the resulting .jar file from the build/libs/ folder into your server's mods folder.
3. Restart the server.

How to Obtain the Weapon

Join the server with operator rights and run the vanilla item-giving command (in versions 1.21+, the format of old NBT tags has been changed to a component system):

/give @s netherite_sword[custom_name='Creative Killer'] 1

After that, any hit with this sword on a player (in any game mode) will instantly send the target to the respawn screen.
