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
