NIRC

A channel-based chat mod for Minecraft Fabric. Adds in-game chat that runs over a secure custom protocol on a dedicated chat server — separate from the Minecraft server you're playing on. Runs entirely client-side, so it works on any server (vanilla, modded, LAN, singleplayer).

Features

  • Channel-based chat with per-channel passwords, MOTDs, and admins
  • Slash commands for sending, switching channels, and admin actions
  • @mention highlight with sound notification
  • Control panel UI for nickname / password / channel management
  • Auto-restore last channel on reconnect

Security

  • TLS 1.2 with client-side certificate pinning
  • Mojang UUID verification — prevents trivial nick impersonation
  • Yggdrasil challenge-response — verifies real Minecraft account ownership
  • Per-IP and total rate limits on connections and messages
  • Channel password lockout after repeated failures
