The minecraft server sends a lot of information to the client that isn't used in most cases. (Like saturation, health of other entities, etc...) However there are mods that do display this information to the player, giving them an advantage over other players that don't use such mods. Some servers with certain gamemodes may consider these advantages to be unfair or even game breaking.

This plugin filters out information likes this making mods such as health indicators and saturation indicators pretty much useless. What information is filtered and what isn't is also easily configurable in the plugins config.yml file.

Dependencies: This plugin requires ProtocolLib and Java 17+ to work.
Make sure to use the latest dev build of ProtocolLib if your server is on 1.21.2+.
Also note that versions below 1.8.8 are not supported!
