LagProtector is a cozy little Paper/Folia plugin that helps your server stay calm when one corner of the world gets a bit too excited—big mob farms, chunky redstone, or chunks that quietly hoard way too many entities and tile blocks.

What you get

• Per-chunk limits for mobs and other entities, so one hotspot can’t tank everyone else’s TPS.
• Caps for mechanics-style blocks (hoppers, furnaces, and friends) per chunk—and optional checks so pistons can’t shuffle tiles across chunk lines just to dodge the limit.
• Optional cleanup waves for things already over the line—you’re not only blocking new spawns, you’re also tidying up.
• Ignore rules for stuff players care about: named mobs, tamed pets, babies, geared armor stands, and more—so the plugin doesn’t feel mean-spirited.
• Folia-friendly scheduling, so it plays nice with region threading.

Requirements

• Paper or Folia 1.21.4+
• Java 21 on the server
