Get the line for Grok Bot (xAI)Connect Supabase first

Three steps

Create a free 0n3 account and connect Supabase. Paste a key or sign in; it lands in your vault, encrypted.
Install 0n3 into Grok Bot (xAI). xAI's always-on Grok Bot. Add 0n3 as a custom connector once, and your Bot can use every app you added, around the clock.
Ask Grok Bot (xAI): whoami. Then: "List users in Supabase".

Add 0n3 to Grok Bot (desktop app)

Open Grok Bot on your computer. In the sidebar, click Connect apps.
At the bottom, click Add a custom connector.
For Name, type 0n3. For Type, pick Remote HTTPS. For Server URL, type https://0n3.app/mcp.
Under HTTP headers, add Authorization with the value Bearer <your 0n token>
Click Add plugin.

Then try it: send your Bot this

"Use 0n3: who am I, and which apps can you reach?"
"Every weekday at 8, use 0n3 to list today's CRM appointments and new Stripe payments, and post a summary to me."

The line above carries a placeholder; 0n3.app/install mints a real key named for Grok Bot (xAI) and fills it in.
