Description

WhitelistGate

WhitelistGate is a lightweight, server-side mod that adds an independent nickname-based whitelist without using or modifying Minecraft's vanilla whitelist.json.

It is designed for server owners who want a separate, simple access list that works in both online and offline mode. Players do not need to install WhitelistGate on their clients, and the mod does not add a custom network handshake.

Features

  • Fully server-side: vanilla clients and clients without the mod can connect.
  • Works with both online-mode=true and online-mode=false.
  • Checks player nicknames case-insensitively.
  • Preserves vanilla bans, IP bans, player limits, and other connection checks.
  • Uses its own configuration file and never touches vanilla whitelist.json.
  • Saves command changes immediately.
  • No accounts, passwords, registration, database, GUI, or client-side installation.

Installation

  1. Install Forge on the server.
  2. Place the WhitelistGate JAR in the server's mods folder.
  3. Start the server.
  4. Configure the whitelist with commands or edit config/whitelistgate/whitelist.json and run /whitelistgate reload.

Do not install WhitelistGate on player clients. It is intended to run only on the server.

Commands

All commands require permission level 3 and can be used by server operators or from the dedicated server console.

/whitelistgate enable
/whitelistgate disable
/whitelistgate add <nickname>
/whitelistgate remove <nickname>
/whitelistgate list
/whitelistgate reload

Enabling WhitelistGate does not kick players who are already connected. Disabling it immediately stops WhitelistGate from restricting new connections.

Offline-mode security warning

On an offline-mode server, players can choose any nickname, including a nickname belonging to another person. A nickname whitelist controls which names may connect, but it does not authenticate users or prove ownership of a Minecraft account.
