NoMobSpawn
by KURGUZ
NoMobSpawn blocks chosen mob types from spawning in a world, and admins manage the blacklist with server commands.
What it does
Admins add a mob ID to the blacklist with the nomobspawn mob command and remove it with nomobspawn remove. nomobspawn list shows the blocked mobs, nomobspawn list clear empties the blacklist, and nomobspawn clear turns off the global spawn block. nomobspawn mob remove purges blacklisted mobs already present in the world, and nomobspawn favorite lets admins keep a mob ID in a favorites list, which nomobspawn favorite remove undoes.
Settings are saved per world in the nomobspawn folder inside each world folder, in a file named nomobspawn.json. Only players at permission level 3 or above can use the default commands, out of five levels numbered 0 through 4. The mod is server-side only, so players join a server without installing it, and it works on singleplayer and LAN worlds as well as on public and private servers. Fabric API is required.
Key features
Mob blacklist
Specific mob types can be added to a blacklist so they no longer spawn in the world.

Commands list the blocked mobs, remove single entries, or clear the whole blacklist at once.
Purging existing mobs
A purge command removes blacklisted mobs that are already in the world, not only future spawns.
Mob favorites
Admins can record mob IDs as favorites and remove them from that list again.

Use cases

Who it’s for: Server owners and admins who want to control which mobs appear in a Fabric world, and single-player or LAN players who want the same control for a local save.
How it compares
Mob Blacklist is also a server-side only Fabric mod under the MIT License, with files for 1.21.1 – 26.1.2, and it is open source. Mob Ignore Me is a Fabric mod for 1.21 – 26.3 that runs on the client or the server as an optional install, is not open source, and is released under All rights reserved. NoMobSpawn differs in that it targets 1.21 – 26.3 with a server-side install that players do not need.
