Player Carpet Extension
by nielsplayz
Player Carpet Extension gives server operators a way to view and manage other players' inventories, through a 54-slot viewer and an auto-switch hotbar system, on top of Carpet Mod.
What it does
The viewer shows a target player's inventory on the client as a 9×6 container, laid out to mirror the player's real inventory and split into marked sections with decorative glass panes. Changes travel both ways: when a viewer picks up, places, swaps or modifies an item, the change is pushed straight to the target player, and the viewer refreshes every 10 ticks, about half a second, so it stays current while the target moves items around. A sync flag stops the two sides from looping endlessly during setup.
The mod is a server-side Fabric extension that builds on Carpet Mod and is needed on both the server and the client. Install Fabric Loader and Carpet Mod first, then place this mod in the mods folder. Once the server starts, the log and the Carpet rules list show the extension registered under its own name. The mod is published for 1.20.4 – 1.21.11 with 14 release versions, and the latest Fabric file is 2.0.0 for 1.21.11. It is released under All rights reserved and is not open source.
Key features
Inventory viewer
Opens a 54-slot view of another player's inventory, arranged in the same structure as the real one.
Bidirectional sync
Item changes made in the viewer reach the target player immediately, and the view updates every 10 ticks.
Inventory Pull
Pulls items from the main inventory slots 9 to 35 into the selected hotbar slot, or fills the whole hotbar when it is empty.
Hotbar auto-switch
Monitors the selected hotbar slot and refills it automatically when it becomes empty, which suits automated farms and PvP servers.

How it compares
Full Inventory GUI is a Fabric mod for 1.20.1 – 1.21.11 that runs on the client and server and is not open source. veryHotbar is a client-side only Fabric mod for 1.21 – 1.21.11 under a Creative Commons Attribution No Derivatives 4.0 license, so it changes nothing on the server. Configured Keep Inventory is server-side only and covers 1.20.1 – 1.21.1, which makes it a server option rather than an inventory viewer. Player Carpet Extension needs the server and every player to run it.
