Meow Anti-Xray
by Meowmiao
Meow Anti-Xray hides unexposed ores from players using X-ray clients by rewriting chunk packets on the server before they reach the player.
What it does
Ore obfuscation runs on the server. Before a chunk is sent, ores that no open face exposes are replaced with ordinary-looking blocks, so an X-ray client sees stone where ore lies underneath. Blocks change to their real form once mined or otherwise altered nearby, and the server world data is left untouched. Vanilla and modded clients join normally and need nothing installed.
The mod keeps a protection score for each player, based on mining behavior, and can label players as suspected cheaters. Settings can be made separately for the Overworld, Nether, End and custom dimensions. A validate command and a status command let server owners confirm that protection is active. Fabric API is required on Fabric. Builds exist for Fabric and NeoForge dedicated servers, with 1.7.0 requiring Java 25 and game versions 26.1 – 26.3.
Key features
Hidden unexposed ores
Ores with no exposed face are obfuscated in chunk data, so the client never receives their real position.
Per-dimension control
The Overworld, Nether, End and custom dimensions can each be configured separately.
Mining behavior scoring
A protection score and mining behavior label help server owners identify suspected cheaters without automatic punishment.
Status and validation commands
Commands check the configuration and report whether protection is active on the server.
