By the way , how many scps are there?

I seeeee it every were litreally every were but i have no idea what it means i thought it was just a containment facility

SCP is a world-wide containment facility which helps in containing anomalous entities, for example, monsters which possess abilities that defy the laws of this world. SCP stands for Secure [​Securing the world from entities], Contain [​Containing the entities] and Protect [​Protecting humanity]. All entities are given a special designation, for example SCP - 999 or SCP - 2736. SCP's are classified into 3 categories based on their difficulty to contain them, Safe, Euclid and Keter. You can get more info on google, but I have absolutely no idea how this is related to minecraft.

There's some information on it here: https://scp-wiki.wikidot.com/faq

I have no idea too!

But literally every SCP is monsters.
And in a Roblox ad, they explain SCP means "Secure. Content. Protect.".
