Install in three steps

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

Questions

What can an AI do with the Neon MCP server?

8 things: projects, branches. Every call runs with your own Neon connection and lands on a receipt.

Do I need to run anything on my computer?

No. 0n3 is hosted. Connect Neon once, install 0n3 into your AI with one line, done.

Where does my Neon key go?

Into your 0n3 vault, encrypted, one record per connection. The AI never sees it.
