Post to Instagram 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 video from your Kreatix library or a public link, posted as a Reel; Instagram takes no text-only post.

For setups without sign-in. The key works like a password, so keep it to yourself.
- In Kreatix, open Settings > AI agent and create a key. It is shown once.

openclaw mcp set kreatix '{"url":"https://api.kreatix.cc/mcp","transport":"streamable-http","headers":{"Authorization":"Bearer YOUR_KEY"}}'What OpenClaw can do on Instagram
A video from your Kreatix library or a public link, posted as a Reel; Instagram takes no text-only post.
| Setting | Values | Needed | What it does |
|---|---|---|---|
media_url | URL | Yes | One video: a link from your Kreatix library (list_posts shows it) or a public YouTube, TikTok, Instagram or Facebook post, which Kreatix imports first. Pictures and carousels are not scheduled. |
caption | string (max 5000) | No | The Reel's caption. At most 30 hashtags and 20 @mentions, or schedule_post refuses the post. |
cover_url | URL | No | The Reel's cover: a picture stored in Kreatix, such as a thumbnail_url from list_posts. With an imported link and no cover, the link's own thumbnail is used. |
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 TikTok link as a Reel on all my Instagram pages tomorrow at 18:00.
- Schedule yesterday's video on my brand's Instagram for Friday 20:00 with the same cover.
- Do any of my Instagram pages have an alarm or need reconnecting?
Instagram rules to know
- Every Instagram post needs a video, and it goes out as a Reel.
- A caption with more than 30 hashtags or 20 @mentions is refused before anything is scheduled.
- Instagram processes the video first; if it is not ready within 30 minutes, the post fails with Instagram's reason.
- Kreatix connects only professional Instagram accounts (Business or Creator).
- If Instagram locks an account, it wants the owner to finish a check on instagram.com; reconnecting does not help.
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 Instagram from OpenClaw?
Connect OpenClaw to Kreatix once, as shown above. Then ask it to post: name your Instagram pages or a page group, the video or text and the time. OpenClaw shows you the plan and posts after you say yes.
Can my agent post photos or carousels to Instagram?
No. Through the agent, Kreatix schedules a video or a text post, and Instagram takes no text-only post. Photos and carousels go out from Kreatix with Publish now.
Why did the agent refuse my caption?
Instagram takes at most 30 hashtags and 20 @mentions in a caption. Kreatix counts them before scheduling, so the post is stopped up front instead of failing on Instagram later.
What if Instagram is slow to process my Reel?
Kreatix keeps checking for up to 30 minutes, and your other posts keep going out meanwhile. If Instagram still has not finished, the post fails with Instagram's own reason.
Will my agent know if an Instagram page is in trouble?
Yes. list_channels shows Kreatix's page alarm when several of the page's newest videos in a row stay under 50 views, and marks a page Instagram has locked or closed. Kreatix tells the agent to raise these with you before planning posts there.
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.
