Bypass Mod Detection

clientcatcher.bypass.mods

• Download it from Modrinth
• Download MCKotlin
• Put both plugins in your Velocity proxy
• And configure the plugin to block the mods and clients of your choice

The plugin is not fully effective, several malicious clients hide their client branding when entering the server or impersonate vanilla clients. However, the plugin can detect several clients such as Forge, Fabric, LiteLoader, Lunar, Vanilla, and others.

It also detects Forge 1.7.10 - 1.12.2 mods.

If you want to use ClientCatcher in Fabric, you can try https://modrinth.com/mod/clientcatcher-fabric

Placeholders

ClientCatcher provides several placeholders for use in other MiniPlaceholders-compatible plugins
