Safety, for parents
Your people.
Your place to play.
Cubelings is a private, whitelisted Minecraft server for one family and the people they invite. Your child says what they want built, and Cog, the AI builder on supported Paper worlds, builds it with them. This page covers who can get in, what Cog will refuse, and what to do if something goes wrong.
- A player list you control. Add the Java and Bedrock accounts you want to join.
- You choose who runs Cog. Switch off any friend and Cog ignores them.
- Limits on requests. Cog is designed to refuse inappropriate content and protect existing builds.
- Work you can check. Cog reports their progress and build checks in Minecraft chat.
- Undo for supported builds. Ask Cog to undo a recorded creative-mode build.
- A direct line to us. Raise a concern from Support in your dashboard and read our reply there.
Illustrated: Cog leaves the existing house alone and builds on clear ground nearby.
No pretending
A builder, clearly introduced as AI
Cog is an AI companion who builds and helps out in the game. Cog is not a person, and we ask Cog to make that clear in conversation. Before a younger player’s first session, it helps to explain the difference.
Keep chat about the world. Cog replies using recent chat and what is around them in the world. Messages to Cog are processed by an AI provider, so players should leave out personal details. The privacy page explains what is sent and where.
What Cog refuses
Three layers of protection
- Cog’s instructions Refuse inappropriate requests, and respect what other players have built.
- The build tools Check recorded work and occupied space.
- You, and us If a response surprises you, tell us what happened through Support.
Each layer helps. None of them means AI will get every situation right.
Who is in the world
Only the people you invited
Add people by their Minecraft Java profile name, or by Xbox gamertag for Bedrock players, in your dashboard. Anyone connecting signs in with their own Microsoft account, and the server checks the player list before they can play. We do not list your world in any public server directory, and sharing the address does not add anyone to the list.
You also decide who can give Cog jobs. Friends can by default; switch anyone off on the same player list and Cog ignores what they say. You always can. Operators get game commands, not Cog.
In the chat
Cog tells you what they did
While they work, Cog posts what they are doing and the results of their checks in the same Minecraft chat your group uses. Ask a follow-up if something is unclear. These messages help you follow along, but they are not a full activity report, and the dashboard does not yet show chat history.
Undo
A way back for recorded builds
Cog records their supported creative-mode builds, so you can ask for one to be undone. Undo does not reverse everything in a world: player actions, survival tasks and later edits may need another approach. The hosting disk takes a snapshot every day, and you can make your own backup from the dashboard before a big change and put the world back to it yourself if you don’t like the result.
How they play
Cog plays carefully
Cog cuts a proper staircase down rather than dropping into the dark, and lights it as they go so you can follow them down and back up. They head home while they still have health left, and check their pickaxe suits the ore before swinging it. Terrain, mobs and unexpected changes can still get in the way, as they can for any player.
Inventions
New items, inside firm limits
Players can invent new items at the crafting table. Each one is judged, checked word by word and tested on a real server before it reaches your world, and you choose whether your world shares them, keeps them private or does not invent at all. Inventions and safety, in full →
Questions
Straight answers
Is it safe for children?
The world is private: nobody joins unless you put their name on the list, and it never appears in any public server list. Cog is built to refuse inappropriate requests and to leave existing builds alone, and we test both. AI can still make mistakes, so play together at first and agree what belongs in chat. Many families find it suits ages eight and up with an adult nearby.
Can Cog be talked into saying or building something inappropriate?
Cog refuses inappropriate requests, including the same request reworded, and we test that. No moderation is perfect: if something slips through, send it to us from Support in your dashboard and we investigate every report.
What if Cog gets something wrong?
Cog counts their own work and reports it in chat, and a creative-mode build can be undone with one request. Undo covers recorded builds, not every action, and a check can miss something; tell us from Support if it does.
Who can join our world?
Only the people on your player list. Add their Minecraft Java profile names, or Xbox gamertags for Bedrock players, in your dashboard; each person signs in with their own Microsoft account, and the server checks the list before they can play. Sharing the address does not let anyone in. A trial has you and up to four friends; paid plans allow more.
Who can give Cog jobs?
You always can. Friends on your player list can too, unless you switch them off under Players in your dashboard. Making a friend an operator gives them game commands, not Cog: that is still this switch. Cog ignores everyone else completely, neither answering them nor acting on what they say. A change applies straight away, without restarting the world.
Do I need to sit and watch?
As with any online game, choose the supervision that suits your child. Only people on your list can join, and everything Cog does is reported in the Minecraft chat where you can read it. A parent view of that chat in the dashboard is on our list; it is not there yet.
