Connect Grok Bot (xAI) to HubSpot
One line gives Grok Bot (xAI) your HubSpot account as tools: 6 endpoints, contacts, companies, deals, called with your own connection. No key in the prompt, a receipt for every call, revoke Grok Bot (xAI)'s access alone any time.
Three steps
- Create a free 0n3 account and connect HubSpot. 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: "Create a contact in HubSpot".
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.
