Concierge

A utility mod, built server-first and most things will work for singleplayer too. Provides:

• Join/leave tracking — logs every join/leave to console, detects first-time joins, tracks last-seen time and cumulative playtime per player (stored as JSON per player).
• Homes — /sethome, /home, /delhome, /homes, with a configurable per-player home limit driven by a permission node (so LuckPerms groups can grant different limits).
• Spawn — /setspawn (admin), /spawn.
• Back — /back, returns you to your previous location (before a teleport or death).
• TPA — /tpa, /tpahere, /tpaccept, /tpdeny, /tpcancel.
• Utility — /feed, /heal, /repair.
• Gamemode shortcuts — /gmc, /gms, /gmsp.
• Virtual crafting/utility GUIs — /anvil, /craft, /stonecutter, /grindstone, /smithing, /trash — open the vanilla screen without needing the physical block.
• Admin inspection — /invsee, /endersee to view/edit another player's inventory or ender chest, live if they're online or saved-to-disk if they're offline. /ec lets any player open their own ender chest.
• Kits — /kit <name> to claim, plus /kit list, /kit create, /kit delete, /kit give to manage them.
• Help — /concierge help prints every command the invoking player currently has permission to use, checked live against their actual permissions.
• Permissions — every command is gated by a permission node, and every cooldown/warmup is also a permission node (not just a flat config value), so LuckPerms can give different ranks different cooldowns and warmup lengths. Node names are identical on all three loaders. Without a permissions mod installed, each loader falls back to sensible defaults (all players / OP-only / a config-file value, per node) — see Permissions on Fabric for the one loader that needs an extra mod for full control.
• Extendable — a small public API (ConciergeAPI) plus loader-agnostic join/leave callbacks (ConciergeEvents) let other mods build on top without touching this mod's code, using the same code on every loader.

This mod has no client-side content (no GUI, no key-binds, no client rendering) — it only needs to be installed on the server.

Commands & permissions

Every command checks its permission node before running, through whatever permission system the active loader provides (see Multi-loader architecture). Node names are identical on all three loaders.

Homes

Spawn & back

TPA

Utility

Gamemode shortcuts

Equivalent to /gamemode <mode> but shorter to type, each with its own permission node so a rank can be granted creative without also getting spectator, etc.

Virtual crafting/utility GUIs

These open the vanilla screen without the physical block being present.

Admin inspection

Both accept any player name the server has ever seen, not just currently-online ones (matched the same way /ban or /whitelist match names). If the target is online, the view is live and edits apply immediately. If they're offline, Concierge reads their saved playerdata/<uuid>.dat file directly, lets you edit a snapshot of it, and writes your changes back to that file the moment you close the screen — armor and offhand items already in the file are preserved untouched even though they aren't shown. If the name has never joined the server (no saved data exists), the command tells you so instead of opening an empty screen.

Kits

Each kit has its own cooldown (default 0 = no cooldown for newly created kits), tracked per player per kit — claiming daily doesn't put starter on cooldown too. Set it with /kit cooldown <name> <seconds> any time after creating the kit. concierge.admin.bypass.cooldown still bypasses any kit's cooldown entirely. Any items that don't fit in the player's inventory when a kit is claimed are dropped on the ground at their feet rather than lost.

Help

Cooldowns & warmups (LuckPerms-controllable)

These aren't tied to a specific command — they're integer permission nodes that tune how the commands above behave, so different LuckPerms ranks can have different cooldowns/warmups (e.g. VIPs get instant teleports, default players wait 5 seconds). Each falls back to the matching value in the config file (server.toml on Forge/NeoForge, server.json on Fabric) when no permission override applies.

Note on kits: kit cooldowns are set per-kit via /kit cooldown <name> <seconds> (see Kits above), not through a permission node — the loaders' permission systems requires nodes to be registered up front at startup, so a dynamic node like concierge.kit.<name>.cooldown isn't practical for kits created later at runtime. concierge.admin.bypass.cooldown still bypasses whatever cooldown a kit has.

All warmups are cancelled if the player moves (configurable via general.cancelWarmupOnMove in the config file).

Example LuckPerms usage:

/lp group default permission set concierge.home.limit 3
/lp group vip permission set concierge.home.limit 10
/lp group vip permission settemp concierge.tpa.warmup 0
/lp group vip permission settemp concierge.tpa.cooldown 0
/lp group default permission set concierge.spawn.set false

Data storage

Data is split across three locations depending on what it's tied to:

World-scoped (coordinates only mean something in the world they were recorded in, so this lives inside the world save and travels with backups/copies of it):

Server-scoped, config directory (settings an admin might hand-edit, alongside the main config file, survives a world reset):

Server-scoped, dedicated folder (constantly-changing runtime data rather than settings, so it's kept out of config/, in its own top-level folder next to world/, config/, mods/; also survives a world reset):

For a server running with the default level name, world-scoped data lands under world/concierge/.... /back locations and pending /tpa requests are not persisted at all — they're kept in memory only and reset on server restart, matching common Essentials-style behaviour.

Config

A server config file is generated on first run — config/concierge/server.toml on Forge/NeoForge (their built-in TOML config systems), or config/concierge/server.json on Fabric (which has no built-in config system, so Concierge manages a JSON file itself) — with cooldowns, warmup durations and the tpa request timeout. These are the fallback values used only when a player has no matching LuckPerms permission override — see Cooldowns & warmups above.

Extending

Other mods can depend on Concierge and reuse its managers instead of reimplementing homes/spawn/tpa/kits.
