- Create a free account at 0n3.app and connect MongoDB: paste a key or sign in through a door. It lands in your vault, encrypted.
- Open 0n3.app/install, pick your AI. A key is made for that AI alone; copy the line it gives you.
- Ask your AI: whoami. It answers with your connected services. Then ask it to aggregate in MongoDB.

Questions
What can an AI do with the MongoDB MCP server?
8 things: aggregate, documents, more. Every call runs with your own MongoDB connection and lands on a receipt.
Do I need to run anything on my computer?
No. 0n3 is hosted. Connect MongoDB once, install 0n3 into your AI with one line, done.
Where does my MongoDB key go?
Into your 0n3 vault, encrypted, one record per connection. The AI never sees it.
