Grok Bot is xAI’s always-on AI teammate. It works on a cloud computer, and you sign in with a Cursor account. Connect PostQueen once and the Bot can list your channels, write posts for PostQueen to schedule, and report how your published posts did, from the desktop app or your phone.

​
Before you start

  • Plans: on The X Subscription, Grok Bot is included on Premium, Super and Ultra, including team seats; Free and Plus do not include it. On legacy plans it is included with Cursor Pro, Pro+, Ultra and Teams, or you can link an individual SuperGrok, SuperGrok Plus, SuperGrok Heavy or X Premium+ subscription (not SuperGrok Lite), or sign in with a seat on a self-serve Grok Business plan. On Enterprise, an admin turns Grok Bot on in the Cursor dashboard.
  • Platforms: the desktop app on macOS, Windows and Linux, and the mobile app on iPhone, iPad and Android.
  • A PostQueen API key. A workspace admin copies it 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 Bot

You add PostQueen from inside a Grok Bot chat.
1

Ask the Bot to connect PostQueen

In a Grok Bot chat, send this message. The address has no key in it.
PostQueen is not in the Bot’s catalog, so the Bot offers to add it as a custom MCP server and shows a card with Connect and Not now.
2

Enter the key in the secure prompt

Choose Connect, then paste your PostQueen API key into the secure prompt the Bot opens. Never paste it into the chat itself: the secure prompt keeps the key out of the chat history.
3

Check the tools

Ask the Bot to list your connected PostQueen channels. The next section shows what a working connection looks like.

​
Check that it works

Ask Grok Bot: “List my PostQueen channels.” It answers with the channels you connected in PostQueen, by name and network. If it says it has no PostQueen tools, open Connect apps in the sidebar, choose Your plugins, and check PostQueen is under Installed. On a phone, tap your avatar, then Connect apps.

​
Good to know

  • The key stays out of the chat. If a key ever lands in a chat message, a workspace admin rotates it under Connections > API key, and you connect again with the new key.
  • Servers you add from chat are your plugins. Open Connect apps in the sidebar, choose Your plugins, and check PostQueen is under Installed. On a phone, tap your avatar, then Connect apps.
  • The address must be public HTTPS. Grok Bot runs in the cloud, so it cannot reach a server on your own computer. api.postqueen.ai is public.
  • On Teams and Enterprise, Grok Bot inherits your team’s Cursor connector policy. On Enterprise, also add PostQueen’s address to the team’s MCP allowlist if you use one. A plugin the team blocks shows as Disabled by team admin.
  • Adding a server by chat is described by Cursor staff on Cursor’s forum, not in xAI’s docs. It works with PostQueen.
  • 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.

​
Other ways to connect

Use the route above. The other PostQueen addresses do not suit Grok Bot:

​
Try this first

The draft appears on your PostQueen calendar, ready for you to check and schedule. Prompts to try has more.

​
Run it on a schedule

Grok Bot runs routines: a routine tells a Bot when to run a workflow. Create one by asking in chat, or open the Bot, choose View conversation details, then Routines. Background routines run while your laptop is closed and can use the Bot’s connected tools, PostQueen included. A Bot can own up to 50 routines.
xAI recommends approval for anything that publishes. Saving drafts keeps you in the loop: the routine writes, and you schedule. Source: xAI, skills, routines and automations.

Troubleshooting

More fixes are on Troubleshooting agents.

​
Is it the same as Grok or Grok Build?

No. xAI has three products with Grok in the name, and each one connects to PostQueen on its own: A connector you add at grok.com, or a server in Grok Build’s config, does not reach Grok Bot. Grok Bot runs on Cursor’s cloud, but Cursor’s own mcp.json does not reach it either.
