Treevite

A server-side Minecraft Fabric mod that implements a tree-based whitelist system for managing player access through an invitation chain.

Overview

Treevite allows you to control who can join your server through a hierarchical invitation system. Starting with just the console as the root administrator, whitelisted players can invite others, creating a "tree" of authorized players. This provides a flexible, organic way to manage server access without manually adding each player to a whitelist.

Key Features:

• Tree-based whitelist system starting from console as root
• Player-to-player invitation system with /invite command
• Invite revocation with automatic privilege adjustment
• Daily invitation rate limits per player (configurable)
• Support for both Java and Bedrock Edition players
• Invite history tracking
• Permission-based commands (via Fabric Permissions API)

Requirements

• Minecraft Server 26.1.2 (or compatible)
• Fabric Loader 0.19.2 or later
• Java 25 or later
• Fabric API

Installation

1. Download the tree-invite.jar mod file
2. Place it in your server's mods folder
3. Start your server
4. (Optional) Install Fabric Permissions API for permission-based command access

Commands

Player Commands

/invite <player> [java|bedrock]

• Invite a player to join the server
• If platform not specified, Java Edition is assumed
• Usernames are looked up via Mojang API (Java) or converted to XUID format (Bedrock)
• Limited by daily rate limit (default: 4 invites per day, resets at 02:00 AM server time)

/revokeinvite <player> [java|bedrock]

• Revoke an invitation you sent to a player
• Only the original inviter can revoke
• Platform optional; if not specified, both platforms are checked
• Players lose access if they have no alternate path back to console
• Invite data is preserved for automatic reinstatement if re-invited

/inviteinfo [player]

• View invitation information
• Lists who invited the player and who they've invited
• Defaults to the command executor if no player specified

Admin Commands

/setmaxinvites <player> <count>

• Set a custom daily invitation limit for a player
• Overrides the global default rate limit
• Set to 0 to disable invites for a player

/setglobalmaxinvites <count>

• Set the default daily invitation limit for all players
• Only accessible to console or high-permission admins

How It Works

1. Initialization: Only the console is whitelisted initially
2. Invitations: Any whitelisted player can invite others using /invite
3. Access Control: A player can join if they have at least one valid path back to console through the invitation chain
4. Revocation: When an invite is revoked, affected players lose access unless they have another path to console
5. Reinstatement: If a revoked player is invited again (directly or indirectly), they automatically regain access

Example Scenario

Console (root)
├── Alice (invited by Console)
│   ├── Bob (invited by Alice)
│   └── Carol (invited by Alice)
└── Dave (invited by Console)
    └── Eve (invited by Dave)

• All players can join
• If Console revokes Dave's invite, Eve loses access (no alternate path)
• If Console revokes Alice's invite, Bob and Carol lose access
• If Console invites Dave back, Eve automatically regains access

Configuration

Configuration is stored in config/tree-invite-messages.json and persists across restarts. The mod manages whitelist data automatically—you don't need to modify the vanilla whitelist.

Permissions

When Fabric Permissions API is available, the following permissions are recognized:

• tree-invite.invite - Allow /invite command
• tree-invite.revoke - Allow /revokeinvite command
• tree-invite.info - Allow /inviteinfo command
• tree-invite.admin.setmaxinvites - Allow /setmaxinvites command
• tree-invite.admin.setglobalmaxinvites - Allow /setglobalmaxinvites command

Database

Treevite uses SQLite for persistent storage by default, but can also use PostgreSQL. All invite relationships and rate limit data are stored automatically.
