Grok Business / Enterprise

If you don’t see Custom under New Connector, a team admin has to add the WitchPrompt MCP URL in the xAI console first. After that, each person connects at grok.com/connectors as above.

After you connect

  • Ask Grok to run a prompt by name. If the template needs values you didn’t give, Grok asks for them in the same chat and runs the filled-in prompt there. No new conversation needed.
  • To stop Grok's access, remove WitchPrompt in Grok, or revoke it underYour connections.
