Hardcore Creative is a Fabric server-side mod that gives the recorded world owner controlled creative access without making every operator, LAN guest, command block, console source, or server player a mod administrator.

It is designed for singleplayer worlds, LAN worlds, and dedicated Fabric servers. The same jar works in all supported environments. On dedicated servers, vanilla clients can connect without installing the mod.

What It Does

Hardcore Creative records a per-world owner UUID and uses that player as the trusted administrator for creative access. The owner can grant, revoke, enable, or disable creative access for selected players.

Authorized players can use their own creative access, but they cannot grant access to other players unless they are the recorded world owner.

Features

Keeps console and RCON from becoming implicit mod administrators.

Ownership System

In singleplayer and LAN, the Minecraft singleplayer owner becomes the mod owner.

On a dedicated server, if the world has no saved owner yet, the first player who initializes the world becomes the recorded owner. After that, administration is locked to that UUID.

This means operators do not automatically become mod administrators. Only the recorded owner controls who gets creative access.
