Post to Instagram from ChatGPT
ChatGPT is OpenAI's AI assistant. On chatgpt.com you can add your own MCP server as a plugin, and ChatGPT then calls its tools in your chats. A video from your Kreatix library or a public link, posted as a Reel; Instagram takes no text-only post.

https://api.kreatix.cc/mcp/YOUR_KEYWhat ChatGPT 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 chat message on chatgpt.com. Type @, pick Kreatix and ask, for example: "@Kreatix which of my pages got the most views this week?"
- 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 ChatGPT
- Pick Kreatix with @ in the prompt box. If ChatGPT reaches for web search instead, say "use only Kreatix" or name the tool, such as get_stats.
- ChatGPT asks you to confirm before it schedules, moves or cancels a post. You can remember your answer for one conversation; a new conversation asks again.
- When Kreatix adds new tools, open the plugin at chatgpt.com/plugins and select Refresh.
- 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 ChatGPT?
Connect ChatGPT 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. ChatGPT 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.
Will ChatGPT post without asking me?
No. ChatGPT treats scheduling, moving and cancelling as write actions and asks you to confirm each one. Reading your pages, queue and stats runs without a prompt, because Kreatix marks those tools read-only.
Can I give ChatGPT my key in a header?
No. ChatGPT can't send custom API keys. Use Sign in with Kreatix (OAuth), or paste the address with the key in it and choose No authentication.
Kreatix schedules one video to every page you run, each with its own platform settings.
