About this Mod

A simple Fabric 1.20.1 mod to list all registered mob types and possible duplicates.

While making a modpack, you might want to know what mobs you ended up with, and if there might be any duplicates. This mod was specifically made for that.

Usage

Add the mod (depends on Fabric API).
Use the /moblister list command to list all registered mobs. The list may be big depending on the modpack, so you might need to check your logs if it's too long to fit in chat.
Use the /moblister duplicates command to list all duplicates. Like above, might need to check your logs depending on the size.

Frequently Asked Questions

mob-lister server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is mob-lister compatible with fabric?

mob-lister officially supports fabric for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with mob-lister – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if mob-lister consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
