Install in three steps

  1. Create a free account at 0n3.app and connect CRM: 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 create a contact in CRM.

Questions

What can an AI do with the CRM MCP server?

15 things: contacts, pipelines, opportunities, tags and more. Every call runs with your own CRM connection and lands on a receipt.

Do I need to run anything on my computer?

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

Where does my CRM key go?

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