Before you start
- Plans: connectors are available to all Grok users. On Grok Business and Enterprise, an admin adds the connector first.
- Platforms: you add the connector on the web, at grok.com.
- A PostQueen API key. A workspace admin copies it, or the ready-made address, from Connections.
Where the API key is: in the app, open Connections > API key. Only a workspace Admin or Super Admin can reveal or rotate it; other members see it masked. A workspace has one key, and each agent card on Connections shows your MCP address with the key already filled in.
Connect Grok
1
Copy your MCP address
In PostQueen, open Connections and copy the address from the Grok card, or build it from your key:
2
Add a custom connector
Go to grok.com/connectors, choose New Connector, then Custom.
3
Paste the address and save
Paste the address as the MCP server URL and save. The key is part of the address, so there is no extra sign-in.
On Grok Business and Enterprise, an admin first adds PostQueen at console.x.ai: choose the team, then Grok Business > Connectors > + Add Connector > Other, and enter the address. Members then connect it at grok.com/connectors.
Check that it works
In a new Grok chat, ask: “List my PostQueen channels.” Grok answers with the channels you connected in PostQueen. If it does not use PostQueen, open grok.com/connectors and check that the PostQueen connector is there and connected.Good to know
- The address carries your API key. Keep it private, like a password. If it leaks, a workspace admin rotates the key under Connections > API key, and you update the connector with the new address.
- Grok on grok.com is separate from Grok Bot and Grok Build. Each one is set up on its own; see the last section.
- Ask for drafts when you want to check first. A draft waits on your PostQueen calendar, and nothing publishes until you schedule it.
- What it cannot do over MCP: change a post’s text or time. Do that on the calendar in the app. The MCP tools lists what it can do.

Is it the same as Grok Bot or Grok Build?
No. xAI has three products with Grok in the name, and each one connects to PostQueen on its own:Next steps
