In-Staff is a robust, high-performance moderation and administration utility mod designed for large modpacks in Minecraft 1.21.1 (NeoForge).

🌟 Features:

  • Server-Authoritative Enforcement — Fast and reliable architecture. Moderation logic runs entirely on the server-side, protecting against bypasses.
  • Client Integrity Scanner — Server-side hash validation ensures players connect using the exact allowed modpack and resource packs, rejecting unauthorized cheat clients.
  • Advanced Punishments — Full support for /isban, /istempban, /isunban, /mute, /tempmute, /kick, and /freeze, backed by a persistent audit trail (/history).
  • Live Inventory Inspection — Bidirectional GUI syncing with /isinvsee and /isendersee. Works safely on both online and offline players without data corruption.
  • World Protection & Ban Items — Blacklist problematic items with /banitem (modes: TOTAL, NO_USE, NO_PLACE) and entity/chunk quarantine protection.
  • Playtime Tracking — Track staff and player session hours with /playtime and /seen via async, lag-free disk saving.
  • Maintenance & Smart Whitelist — Easily toggle server maintenance (/maintenance) and manage who can join (/swhitelist).
  • Multi-Language — Native support for English (en_us) and Brazilian Portuguese (pt_br).

Feel free to use it however you want in your servers and modpacks, just give credit to TioNickZeus!
