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

Commands

Server

This mod connects to a fixed server, intended
for a small invite-only community. There is no built-in mechanism to point
it at other servers.

Requirements

• Minecraft 1.21.10 – 1.21.11
• Fabric Loader ≥ 0.16
