About this project

What does Server Utilities add?

Server Utilities

A Minecraft server-side utility mod built on NeoForge, providing convenient teleportation, account security, inventory inspection, and private message monitoring for server admins and players.

  • Supported version: Minecraft 1.21.1 / NeoForge
  • Mod ID: server_utilities
  • Mod version: see mod_version in gradle.properties

Features

1. TPA Teleport System

Teleport requests between online players with complete safety and fairness mechanics:

Command Description
/tpa <player> Request to teleport to the target player
/tpahere <player> Invite the target to teleport to you
/tpaccept Accept a teleport request
/tpdeny / /tpadeny Deny a teleport request (both aliases work)
/tpalock Lock / unlock teleport requests
  • Stand-still check: You must remain stationary for a duration after accepting; moving resets the timer
  • Experience cost: Cost based on distance, with an extra fee for cross-dimension teleports
  • Timeout: Requests expire automatically
  • Clear feedback for offline targets, self-lock, target-lock, etc.

2. Login / Register System

Password protection for your server:

Command Description
/register <password> <confirm> (alias /reg) Register on first join
/login <password> (alias /l) Log in with an existing account
/logout Delete your local account data
  • Unverified players are locked high above the spawn area, blocked from chatting and commands (except /login /register /logout), with periodic reminders
  • Auto-kick on login timeout
  • Data safety: full player data (inventory, ender chest, XP, health, hunger, position) is backed up / cleared / restored around login
    • Unauthenticated players have their data cleared; it is fully restored after a successful login
    • Backups are also written to disk (world/playerdata/auth_backups/) so data survives a server restart
  • Join / leave messages of unauthenticated players are suppressed to hide their online status

3. Inventory / Ender Chest Inspection (Admins)

Command Description
/invsee Open the inventory of the player you are looking at
/invsee <player> Open a specific player's inventory (including offline players)
/endersee Open the ender chest of the player you are looking at
/endersee <player> Open a specific player's ender chest (including offline players)
  • Requires permission level 2 (admin)
  • Online players are auto-completed when typing a name; offline players can still be typed manually
  • With no argument, defaults to the player in your line of sight (distance configurable)

4. Private Message Monitoring (Admins)

  • Vanilla /msg, /tell, /w private messages are monitored
  • Admins see them in real time in gray italics: <playerA> whispers to <playerB>: message (format configurable)
  • Every private message is also written to the server log ([MSG] sender -> receiver: content)

Configuration

Config file: config/server_utilities.toml, containing these groups:

  • [tpa]: tpa_enabled, lock_enabled, timeout_ms, stand-still duration, XP cost settings, etc.
  • [login]: enabled, timeout_seconds, reminder interval, etc.
  • [invsee]: invsee_enabled, endersee_enabled, invsee_look_range (line-of-sight distance, default 5), etc.
  • [msg]: msg_monitor_enabled, msg_monitor_format (admin monitor message format)
