NSvc — Virtual Chests for Fabric

NSvc adds command-based virtual chests to your Fabric server. Create private or public chests, open them without placing physical blocks, and manage everything with permissions, deletion protection, auto-save and localization.

Environment: Server-side Fabric mod
Requires: Fabric Loader, Fabric API
Minecraft: See the Versions tab

✨ Features

• Virtual chests — open vanilla-style 9x3 / 9x6 container GUIs via commands.
• Private & public chests — private chests are owner-only; public chests are shared.
• Two sizes — small = 27 slots (3 rows), large = 54 slots (6 rows). Default: large.
• Permission system — admins use the command tag nsvc_admin. Console is admin by default.
• Safe deletion — private chests require confirmation; public chests have a 3-game-day cooldown; admins can delete instantly.
• Data persistence — chest data is saved automatically and can be saved manually with /NSvc save.
• Localization — uses nsvc.* translation keys.
• Tab completion — player names, allplayer, small, large.
• Legacy command compatibility — old command style still works.
