Fabric Utility
Fabric Utility bundles chunk-based protection, player nicknames, proximity chat and item customization into one package for server administrators on Fabric.
What it does
Chunk tagging stores persistent tags directly on chunks and on individual 16-block-tall subchunks, using the tagchunk command. Protected areas build on those tags, with a built-in invulnerability tag, custom tag values and bypass lists that let trusted players enter protected regions. Other mods can read the same custom tags through the Fabric Utility API.
Nicknames appear automatically once set, and a full nickname system keeps a history of changes and gives administrators control over them. Chat formatting uses MiniMessage, and the built-in proxy chat offers several communication channels, including proximity chat and chat areas that work with the chunk tagging system, without any extra mod. Entities can be petted through a configurable interaction, and items can be given custom names and descriptions in-game with the Inscriber.
Fabric Utility is licensed under CC0 1.0 Universal and is open source. Installation covers the server and each player's game. Files are published for Fabric only, for the 1.20.1 – 1.21.1 range, and the latest file targets 1.21.1. Action Deck requires it.
Key features
Chunk and subchunk tagging
Persistent tags can be stored on whole chunks or on 16-block-tall subchunks, and each tag can carry a custom value.

Regions can be protected with a built-in invulnerability tag, and a bypass list lets chosen players still enter.
Advanced nicknames
Players get nicknames shown automatically, with a recorded history and administrative controls over every change.
MiniMessage chat formatting
Chat and item text accept MiniMessage tags, so server staff can style messages and item names.
Proximity and chat areas
Built-in proxy chat provides proximity chat and chat areas, tied to chunk tagging for simple management.
Item inscriber
Players and administrators can rename items and edit their descriptions directly in the game.
Configurable entity petting
