• /plugins, /pl, /ver, /version, /about, /help, /icanhasbukkit
• /bukkit:... and /minecraft:... commands, like /bukkit:plugins
• Commands with a plugin name in front, like /essentials:home. The part before the colon is the plugin's name
• Plugin commands in the TAB list, and TAB suggestions after a hidden command
• The "You don't have permission" reply, which quietly proves a plugin is installed
• The server software, in the server list and on the F3 screen in game
• The list of plugin channels every player's game gets on join, which names plugins like WorldEdit outright
• The query port, which normally hands your full plugin list to anyone who asks

Every blocked command gets exactly the reply a made-up command gets, so players can't tell anything was hidden.

• Choose what players see. "Unknown command", an empty list, a fake plugin list, or your server's "no permission" message.
• Fake plugin list. Make a heavily modded server look like plain Paper with a couple of harmless extras.
• Blocks popular plugin commands. /essentials, /lp, /we, /co, /mv, /dynmap and more all answer "Unknown command".
• Fake server brand. Show vanilla, or anything you like, in the server list and on the F3 screen.
• Aggressive mode. Hide every plugin command unless a player has permission for it.
• Warns your staff. Notices when someone goes looking and tells staff in game. Normal /help use is ignored.
• Discord warnings and automatic kicks. Get every warning in a Discord channel, and kick or ban probers automatically.
• Honeypot commands. Made-up commands no normal player would type. One use and you know who is snooping.
• Staff bypass. Staff see the real server and are never counted.
• Every message editable in messages.yml.
• Instant reload. Run /pluginguard reload, no restart.

Three downloads: PluginGuard-<version>.jar for 1.21.x, PluginGuard-<version>-mc26.jar for 26.1 and 26.2, and PluginGuard-<version>-mc263.jar for 26.3. Grab the one that matches your server.

1. Put the jar that matches your Minecraft version in your plugins/ folder.
2. Start the server.

That's it, everything is on by default. To change anything, edit plugins/PluginGuard/config.yml and run /pluginguard reload. Every setting is explained in the file and in the guide.

Short form: /pg. All need pluginguard.reload.
