Rebbel in Grok
Add Rebbel to Grok yourself, as a custom connector. Then draft posts, launch campaigns and schedule posts in plain English — nothing goes out until you say so.
Publishes to Facebook, Instagram, X, Threads, Bluesky, LinkedIn — Personal, and Pinterest. Straight from Grok, and only after you schedule each post. TikTok and YouTube posts are made in the Rebbel dashboard.
Add it yourself
Read this first. This is a custom connector you add yourself. Rebbel isn't one of the connectors built into Grok, and Grok labels it Custom. These steps are for grok.com in a web browser.
https://app.rebbel.io/api/mcp- 1Open Connectors. On grok.com, open Plugins (bottom left), then the Connectors tab, and choose New Connector.
- 2Choose Custom. Pick Custom, the option to add your own custom connector.
- 3Name it and paste the URL. Name it Rebbel, paste the address above as the Server URL, and select Add Connector.
- 4Allow access on Rebbel. Grok asks you to complete authentication in a popup window, and Rebbel's consent page opens there. You'll need a Rebbel account. Allow access.
- 5Check it's connected. Rebbel now shows under Connected, with app.rebbel.io beneath it.
- 6Ask with @Rebbel. In a chat, type @Rebbeland pick it from the Connectors list that appears, then ask, like “draft this week's posts” or “list my Rebbel brands.” The first time you use Grok, it may ask you to confirm your age before the message sends.
What you can do. Once Rebbel is added, ask in plain English: set up a brand, draft posts, launch a campaign, schedule posts and publish to the channels you've connected in Rebbel. These steps work on Grok's free plan, on grok.com. On Grok Business and Enterprise, xAI's docs say an admin sets up connectors. Grok's screens and plans are xAI's to change.
Nothing goes out until you say so. Anything Rebbel drafts lands in review in your Rebbel account. Nothing publishes or spends until you schedule it, checked on Rebbel's servers, whichever app you ask from.

Things people say to it
Common questions
- Is Rebbel an official Grok connector?
- No. Rebbel isn't one of the connectors built into Grok. Grok calls it a custom connector: you add it yourself with Rebbel's server address and allow access on Rebbel's own page.
- Can Rebbel post from Grok without my say-so?
- No. Anything that would publish or spend needs your explicit go-ahead, checked on Rebbel's server — asking from Grok follows the same rules as the dashboard.
- Which channels can Rebbel publish to from Grok?
- Rebbel publishes to Facebook, Instagram, X, Threads, Bluesky, LinkedIn — Personal, and Pinterest, through the accounts you connect in Rebbel on rebbel.io, and only after you schedule each post. TikTok and YouTube posts are made in the Rebbel dashboard.
- Is Rebbel free to use from Grok?
- Rebbel is free to start. Every new account gets its brand guide, strategy and first post free, with no credit card; a 7-day free trial covers the rest. It works on Grok's free plan; Grok's own plans and limits are set by xAI.
- Can I add Rebbel in Grok Business or Enterprise?
- xAI's docs say connectors in Grok Business and Enterprise are set up by the team's admin, so ask your admin to add Rebbel with the server address above.
- Will Grok ask before Rebbel drafts something?
- Grok went ahead without asking when we asked for a draft, and the draft landed in review in our Rebbel account. Nothing publishes or spends until you say so, checked on Rebbel's servers whichever app you ask from.
