Videos and images

In grok.com, give it a public link: a Dropbox link ending in ?dl=1, a Google Drive file shared with anyone, or a file on a website. Superbridger imports it and checks it for every platform. Earlier uploads can be reused too. Grok Build can also upload files from your computer with start_upload's upload command.

What Grok can do in Superbridger

  • See your brands, social accounts and calendar
  • Check a post for each platform, then publish it or schedule it
  • Move, cancel, retry or delete posts
  • Add videos and images
  • Read how your posts did, per post and per platform

You stay in charge

  • Every post is checked against each platform's rules first, and you see what each one will get
  • Your AI app asks before it publishes, moves, cancels or deletes anything
  • Rather it only reads? Untick posting when you connect it
  • It works in the one team you pick, with that team's brands
  • Superbridger never sees your chats, only the requests the app makes
  • Disconnect it any time in Settings → Connected apps

FAQ

Grok and Superbridger

Can Grok post to X for me?

Yes, through Superbridger: connect Superbridger to Grok, and it can publish or schedule to your X account and the other accounts you connected in Superbridger. Posts to X use Superbridger's X credits: 1 per post, 15 with a link.

Does it work in Grok Build too?

Yes. Add Superbridger with grok mcp add, and Grok Build signs in in your browser the first time it uses it. In the terminal it can also upload videos from your computer.

Can Grok post to Instagram, Facebook, YouTube, TikTok, LinkedIn and X?

Yes, through Superbridger. Connect Superbridger to Grok, and it can publish or schedule a post to the accounts you connected in Superbridger: Instagram, Facebook, YouTube, TikTok, LinkedIn and X. TikTok posts arrive as a draft in the TikTok inbox, to finish there.

Will Grok post without asking me?

Grok uses connected tools by itself. To approve every post, ask it to show you the post before it publishes, or connect it read-only: untick posting on Superbridger's Allow screen. Superbridger checks every post for each platform first.

Is the MCP server free?

It's included in every Superbridger plan and in the free trial, at no extra cost. Posts made from an AI app count toward the plan's monthly posts and X credits, the same as posts made on the website.
