Post to X from Grok
Grok is the AI assistant at grok.com and in the Grok apps. Connectors let it use outside services, and a custom connector adds your own MCP server, such as Kreatix. A text-only post or a video with text, cut to X's 280-character count.

A text-only post or a video with text, cut to X's 280-character count.
| Setting | Values | Needed | What it does |
|---|---|---|---|
caption | string (max 5000) | No | The post text. Only the first 280 go, counted X's way: a link is 23, an emoji 2. A text-only post needs it. |
media_url | URL | No | One video to attach: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post. Leave it out for a text-only post. |
Ask in plain words
A chat message at grok.com. For example: "Which of my pages got the most views this week?" Grok calls Kreatix when the question is about your pages.
- Post this on X tomorrow at 10:00: Our spring sale starts Monday, 30% off everything.
- Share my newest video on X and LinkedIn tomorrow at 9:00 with the same caption.
- What do I have planned on X this week?
X rules to know
- Only the first 280 characters go to X, counted X's way: a link counts as 23 and an emoji as 2.
- A longer text is cut, not refused, and never in the middle of a link or an emoji.
- A text-only post needs a caption.
- get_stats has no numbers for X.
Tips for Grok
- Grok reaches Kreatix from its own servers over the internet, so nothing has to run on your computer.
- After you connect, Grok discovers Kreatix's seven tools by itself. Ask in plain words; you don't need tool names.
- The agent checks the pages, caption and time with you before it posts. It cannot delete pages, read messages or change your account, and you can remove it any time in Settings > AI agent.
Questions
How do I post to X from Grok?
Connect Grok to Kreatix once, as shown above. Then ask it to post: name your X pages or a page group, the video or text and the time. Grok shows you the plan and posts after you say yes.
What happens to a caption longer than 280 characters?
Kreatix sends the longest start that fits in 280, counted the way X counts: a link is 23 and an emoji 2. It never cuts a link or an emoji in half.
Can I post text only, without a video?
Yes. X, LinkedIn and Facebook take text-only posts. Leave media_url out and give a caption.
Can my agent read how my X posts did?
No. get_stats measures Instagram, Facebook, TikTok and YouTube; X, LinkedIn and Pinterest have no numbers in Kreatix.
Can I share a TikTok or YouTube video on X?
Yes. Give the agent the public link: Kreatix imports the video into your library first, then attaches it to the X post with your text.
Do I need a paid Grok plan?
Grok's docs say connectors are available to all Grok users. On Grok Business and Enterprise, a team admin first provisions the connector in the cloud console. Scheduling posts still needs a paid Kreatix plan or a running trial.
I made a new Kreatix key. How do I update Grok?
On the key route, the key is part of the address. Remove the Kreatix connector in Grok and add it again with the new address, then delete the old key in Kreatix under Settings > AI agent.
Kreatix schedules one video to every page you run, each with its own platform settings.
