GlymeraPermissions - Command Access Control

Control which commands your players can use. Whitelist or blacklist mode, subcommand-level precision, instant in-game management - no restart needed.

Most actual version only working for Hytale stable 5 ! Don't miss my other exciting projects — take a look at GlymeraCraft's Profile Discord: https://discord.gg/s5NRFWfxgy

What is GlymeraPermissions?

Hytale has no built-in command permission system. By default, every command registered by any plugin is available to every player - unless the plugin developer manually added an OP check. If they forgot, the command is wide open.

GlymeraPermissions fixes this at the server level. It scans all registered commands at startup and restricts access based on your configuration. Commands blocked by GlymeraPermissions require OP status to execute. Commands you whitelist remain available to everyone.

Important: GlymeraPermissions adds a security layer on top of existing plugins. It can block commands that a plugin left open, but it cannot override restrictions that a plugin enforces internally. If a plugin has its own OP check built in, that check still applies even if GlymeraPermissions allows the command. Think of it as a gate before the door - GlymeraPermissions can close the gate, but it cannot open a locked door behind it.

Pure server-side plugin - no client mod required.

How It Works

On server startup, GlymeraPermissions scans all registered commands (including subcommands). Depending on your chosen mode:

• Whitelist mode (default, recommended): All commands without existing permissions are blocked for non-OPs. Only commands you explicitly whitelist are available to everyone.
• Blacklist mode: All commands remain open. Only commands you explicitly blacklist are restricted to OPs.

Commands that already have permissions set by their own plugin are not touched - they are already protected.

OPs always have full access to all commands regardless of GlymeraPermissions settings.

Commands

All /perms commands are OP-only.

Subcommand Precision

You can control access at the subcommand level using dot notation:

• /perms add tpp → allows ALL /tpp subcommands (set, del, show, name)
• /perms add tpp.set → allows ONLY /tpp set, rest stays blocked
• /perms add tpp.show → allows ONLY /tpp show

This works at any depth for nested subcommands.

Configuration

Config file is generated at first startup:

mods/de.glymera_GlymeraPermissions/config.json

{
  "mode": "whitelist",
  "whitelist": [
    "help",
    "tell",
    "msg",
    "w"
  ],
  "blacklist": [],
  "logBlocked": true
}

Changes made via /perms commands are automatically saved to config.

Installation

1. Place GlymeraPermissions-1.0.0.jar in your server's mods/ folder
2. Start (or restart) the server
3. Done! Default whitelist mode is active.

Features

• Two modes - Whitelist (secure by default) or blacklist (open by default)
• Subcommand precision - Control access down to individual subcommands
• Live management - Add/remove/switch mode in-game, no restart needed
• Automatic scanning - Finds all commands from all plugins at startup
• Re-scan on demand - /perms scan after hot-reloading plugins
• Non-destructive - Only adds restrictions, never removes existing ones
• OP passthrough - Operators always have full access
• Console logging - See exactly which commands were restricted
• No asset pack - Pure server-side, no client downloads needed

Good to Know

• GlymeraPermissions runs its scan 3 seconds after startup to ensure all plugins have registered their commands
• Commands that already have permissions from their own plugin are skipped
• GlymeraPermissions cannot grant access to commands that are internally restricted by their source plugin
• The /perms command itself is always OP-only and cannot be accidentally locked out
• Compatible with all other Glymera plugins
