How do I connect Grok to PostEverywhere?

Add PostEverywhere to Grok as a custom connector from the Agents page, then sign in and click Approve. No API key needed.

Updated 23 October 2026

Open Agents in the sidebar, choose Grok and click Open Grok connectors, then add PostEverywhere as a custom connector. You sign in with your PostEverywhere account, so no API key is needed.

Steps

  1. In PostEverywhere, click Agents in the sidebar (app.posteverywhere.ai/agents?agent=grok) and choose Grok. If you have not connected a social account yet, the page asks you to do that first. Click Connect a social account.
  2. On Grok Business or Enterprise, a team admin adds the connector first at console.x.ai: Grok Business → Connectors → Add Connector → Other. Personal plans skip this step.
  3. Click Open Grok connectors. Grok's connectors page opens in a new tab, and the address https://mcp.posteverywhere.ai is copied for you.
  4. In Grok, click New Connector, then select Custom.
  5. Paste the address. If nothing pastes, click Copy next to the address on the Agents page.
  6. A PostEverywhere sign-in window opens. Sign in if asked, check the account next to Signed in as, then click Approve.
  7. Ask Grok: "Show me my connected social accounts on PostEverywhere." The Agents page has a Copy button for this prompt.

If you have no plan or trial yet, PostEverywhere asks you to choose one at step 6, then brings you back to Approve.

On the Grok phone apps, connectors are under Settings → Connectors. Add PostEverywhere once and it works on the web and on your phone.

Disconnect

  1. In PostEverywhere, open Agents and click the Connected tab.
  2. Find the Grok connection and click Disconnect. Click Disconnect again to confirm.

It stops working at once. The list uses the name Grok gives itself, so it may read a little differently. Only an owner or admin of your team can disconnect. If you are a member, ask one of them. The same connection is also listed on Developers → API Keys, where the bin icon revokes it.

To use Grok again, add the connector again in Grok and sign in.

If it does not connect

The sign-in popup hangs on "Connecting" Close the popup and try once more.

For other causes, such as a blocked sign-in window, the wrong account or no plan yet, see My AI agent cannot connect to PostEverywhere.
