- Create a free account at 0n3.app and connect Calendly: 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 list events in Calendly.

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