NovaShield Client
by Fix4Dev
NovaShield Client is a Fabric mod that lets servers verify the mods a player has installed before the connection is accepted.
What it does
Joining a server that supports NovaShield client verification prompts the client to report its installed Fabric mod IDs, their versions, the NovaShield Client version, and a connection challenge generated at random. The server compares that list against its own mod whitelist. If every mod is approved the connection goes ahead, and if one is not the connection is rejected. The server then associates the reported mod list with the connected player.
Only that mod information is transmitted, and data is sent only to a connecting server that supports NovaShield client verification. The mod is client-side only, so servers do not need to install it. It requires Fabric Loader 0.19.3 or newer and Fabric API, and targets Minecraft 26.2. The mod is not open source; it is released under All rights reserved, and the latest Fabric file is 1.0.0 for 26.2, published 2026-07-31.

Server whitelist check

Who it’s for: The mod suits Fabric server owners who want to enforce a client mod policy, and players on those servers who run Minecraft 26.2 with Fabric.
