Post to X from OpenClaw
OpenClaw is a self-hosted gateway that runs on your own machine and connects an AI agent to chat apps such as WhatsApp, Telegram, Slack, Discord and iMessage, so you can message your assistant from anywhere. 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 message to your OpenClaw assistant from any chat app it is connected to, or from the Control UI chat. For example: "Plan this video for my brand group tomorrow at 18:00."
- 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 OpenClaw
- Plan posts from your phone: message OpenClaw on WhatsApp or Telegram, and your Gateway calls Kreatix.
- Saving a server doesn't prove it works. openclaw mcp doctor kreatix --probe connects and lists the tools Kreatix offers.
- Keep the key out of config literals: write "Bearer ${KREATIX_API_KEY}" in the header and set the variable for the Gateway. openclaw mcp doctor warns about keys written in plain text.
- 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 OpenClaw?
Connect OpenClaw 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. OpenClaw 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.
MCP server or the Kreatix skill?
Either works. The MCP server gives OpenClaw Kreatix's seven tools directly and supports Sign in with Kreatix. The ClawHub skill (@abrahimceylan/kreatix) teaches the agent to call the same server with curl and your key in KREATIX_API_KEY.
How do I sign out?
Run openclaw mcp logout kreatix. It removes the saved sign-in and keeps the server entry. To cut access for good, also delete the key in Kreatix under Settings > AI agent.
Kreatix schedules one video to every page you run, each with its own platform settings.
