Disable Spawner Mob Spawns
by Kirosya
Disable Spawner Mob Spawns adds a game rule that stops mob spawners from producing mobs, while natural spawning stays untouched.
What it does
Once the mod is loaded, a new game rule named spawnerBlocksEnabled controls whether mob spawners release anything. Setting it to false stops every spawner in the world, and the rule can be changed with a command at any time. The change is meant for servers that want spawners disabled but still want natural mob generation in the world.
The mod ships as a datapack as well as a loader mod, so a world or server can use it without installing a loader-specific file. The datapack is placed in the world or server datapacks folder, and a reload or server restart applies it. Mob farms that do not rely on spawners are not affected, and natural spawning continues as before.
Server owners who only need the datapack can skip the mod jar entirely. The project runs on Fabric, Forge, NeoForge and Quilt, and the files target 1.21.9 – 26.3. The mod is released under the MIT License and is not open source.
Key features
Spawner game rule
A new game rule, spawnerBlocksEnabled, turns spawner mob output off when set to false.
Natural spawning kept
Mobs still spawn naturally in the world, so only spawner-based sources are stopped.
Datapack version
A datapack form lets a server apply the change by dropping a ZIP file into the datapacks folder.
Reload or restart
The change takes effect after a datapack reload or a server restart, without editing world files by hand.

Use cases
Servers limiting spawner farms
A server owner who wants spawners inert can set the rule once and keep the rest of the mob spawning in place.
Mob farms without spawners
Farms built around natural spawning or spawn eggs run as before, since the rule only affects spawner output.
Who it’s for: Server owners who want to stop mob spawners on a server, and players who run their own world and want the same control.

This datapack flips the new gamerule spawnerBlocksEnabled to false, so mob spawners stop spawning mobs. Natural spawning is untouched. Drop the ZIP into your world/server datapacks/ folder.
