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
