Mod Viewer
by haykam
Mod Viewer lets server operators and permitted players open an in-game screen that lists the mods loaded on a Fabric server.
What it does
Mod Viewer is a server-side interface for browsing loaded mods. A player with access runs the modviewer command, which opens a paginated list of mods to choose from. Selecting an entry shows that mod's name, description, authors and dependencies.
Out of the box, operators at permission level two can open the list. The mod also supports permission keys, so the modviewer.command key can grant access to other players instead. Fabric API is required, and the mod is published for Fabric only, with files for 1.18.2 – 1.21.1 and 15 release versions. The code is open source under the MIT License, and fabric-permissions-api is bundled inside the mod.
Key features
Paginated mod list
The viewer shows loaded mods as pages a player can move through and select from.
Mod details screen
Selecting a mod displays its name, description, authors and listed dependencies.
Command access
The modviewer command opens the screen, and it works for players with the matching permission.
Permission key control
The modviewer.command permission key controls who can use the command, so operators can grant it without giving operator status.

Use cases
Checking a server's mod list
Players joining a modded server can see which mods are loaded and read what each one does.
Reviewing dependencies
A player can inspect a mod's listed dependencies from the same screen before adding a similar mod.
Who it’s for: Server owners who want players to see the installed mod list in game, without a web page or a separate file to share.
How it compares
Simple input Viewer is a Fabric mod under the MIT License for 1.20.5 – 1.21.5, client required and server optional, and it is not open source. NBT Viewer is client-side only for 1.20.4 and is licensed under Creative Commons Attribution Non Commercial 4.0, so it is not open source. Mod Viewer runs on the server alone and lists loaded mods rather than inspecting inputs or data.
