Fabric Utility

Store persistent tags directly on chunks or individual 16-block-tall subchunks using /tagchunk.

The built-in invulnerability tag can protect areas from:

• Block interaction by unauthorized players
• Explosions and TNT
• Falling block damage

Tags support custom values and player bypass lists, allowing protected regions while still granting access to trusted players.

Custom tags can also be utilized by other mods through the Fabric Utility API.
