Mutualzz Voice (client mod)

Hear and talk in Mutualzz voice from inside Minecraft.

This is a Fabric client mod for your PC. The server needs the official Mutualzz Bridge plugin, which connects to Mutualzz’s hosted hub.

Without this mod you can still /mzvoice join for presence in the Mutualzz app — you just won’t get in-game audio.

What you need

Install (players)

1. Install a Fabric profile for Minecraft 26.1.x (use the Fabric installer or a launcher that supports Fabric).
2. Download these jars (matching your Minecraft version):
   • Fabric API — Modrinth
   • Amecs — Modrinth
   • Mutualzz Voice — official jar from the Mutualzz GitHub Release Mutualzz Minecraft v… (tag minecraft-v…; same release as the Bridge plugin — not third-party mirrors)
3. Put all three jars in your Minecraft mods folder.
   • Prism / MultiMC / CurseForge: open the instance → Mods folder
   • Vanilla launcher: .minecraft/mods
4. Launch Minecraft with the Fabric profile.
5. Join a server that has Mutualzz Bridge.
6. Link your account if you haven’t: /mzlink (follow the code in Mutualzz settings).
7. Join voice: /mzvoice join
   Optional room name: /mzvoice join lobby (tab-complete shows rooms bound on that server).
   Leave with /mzvoice leave.

When you’re connected, a green Mutualzz Voice label appears in the top-left of the screen.

Controls

Open the settings screen anytime with Ctrl+O (volume, mic, PTT, mute, per-user).

You can also use shortcuts (rebind under Options → Controls → Mutualzz Voice):

Settings are saved in config/mutualzz_voice.json.

Troubleshooting

• No green HUD after /mzvoice join — Confirm Fabric API + Amecs are loaded, and the server has Mutualzz Bridge online.
• Joined but can’t hear anyone — Check output volume in Ctrl+O, and that you’re not deafened (Ctrl+D).
• Nobody can hear you — Unmute (Ctrl+M), raise mic sensitivity, or switch to push-to-talk and hold V.
• Kicked / left and it keeps reconnecting — Update to the latest official mod; session ends cleanly when you’re removed from the channel.
• Wrong Minecraft version — This mod only supports 26.1.x.
