ClientBridge
by SenpaiPeace
ClientBridge lets Fabric clients report their active mods to a Paper server, and lets server owners whitelist or blacklist specific mods.
What it does
The client part of ClientBridge is a Fabric mod, and its server part is a Paper plugin; the pair cooperate to share mod information. The Fabric part sends the list of active mods to the server, using a communication standard similar to the one Forge uses, which fills a gap for Fabric clients on Paper servers. Server owners can then see which mods each connected player runs.
Server owners can set a whitelist or a blacklist to allow or restrict particular mods on the server, and a command shows the mods used by a specific player. The mod is described as transparent and customizable. It needs Architectury API and Fabric API on the client, and the server and every player need it, because the environment is client and server. Files are published for Fabric, targeting 1.21 and 1.21.10, with fabric-1.0.0-beta.4 for 1.21.10 as the latest beta. The code is not open source and is released under All rights reserved.
Key features
Mod list transmission
Fabric clients send their list of active mods to the server, a path similar to Forge's own mod list exchange.
Mod whitelist and blacklist
Server owners configure which mods are allowed or restricted, so only chosen mods can join the server.
Mod view command
A command lets an operator list the mods a specific player is running.
Modular client and server parts
A Fabric client mod and a Paper server plugin split the work, with each side handling its own half of the exchange.

Use cases
Who it’s for: Server owners running Paper who want visibility into, or control over, the mods their Fabric players use. Players on those servers install the client side.
How it compares
ClientBlock is a Fabric mod that runs on the server alone, released under the MIT License, with files for 1.21 – 1.21.11, so clients need nothing extra. Custom Whitelist Text is also server-side only and covers 1.21.1 – 1.21.11, but it is not open source. Poime's Mod Checker is open source under the MIT License and runs on both client and server, with files for 1.21.4.
