Anti-Mod Detect
This mod stops multiplayer servers from seeing what mods you have installed. The mod is purely client sided. Lets you use blacklisted mods on servers like mcpvp.com.
How to use:
Open the Minecraft options page and look at the bottom left of your screen for the NP button, put the filter on enabled and block all or block specific mods / packets, blocking something prevents that mod from interacting with the server. The text box can be used to manually add mod channels to filter.
Note: Mods that interact with the server may not work correctly if disabled (purely client sided mods arent affected)
