Anti noclip through world

I used to have a mod that kept people from nocliping through the world. Now i have looked into Uclip but from what i have read it only stops people from nocliping through props.

Unless anyone knows whether or not it does stop people from going through the map or if you know what mod I’m talking about, the help would be great

Im pretty sure Uclip stops you from no-clipping through the world too. A friend of mine used it on his server.
