Post to Facebook 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 posted as a Reel on your Facebook Page, or a text-only Page post.

https://api.kreatix.cc/mcp/YOUR_KEYWhat ChatGPT can do on Facebook
A video posted as a Reel on your Facebook Page, or a text-only Page post.
| Setting | Values | Needed | What it does |
|---|---|---|---|
media_url | URL | No | The video, posted as a Reel: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post. Leave it out for a text-only post. |
caption | string (max 5000) | No | The Reel's description, or the whole post when there is no video. A text-only post needs it. |
cover_url | URL | No | Set as the Reel's cover once Facebook has finished processing the video. If that takes too long, the cover is skipped. |
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 on my Facebook page tomorrow at 9:00: We're open this Sunday from 10:00 to 18:00.
- Share this Instagram Reel link on all my Facebook pages tonight at 20:00.
- Cancel the Facebook post planned for Friday.
Facebook rules to know
- Videos go out as Facebook Reels.
- A text-only post needs a caption.
- The cover is added after Facebook finishes processing the video; if that takes too long, it is skipped.
- When Facebook blocks a post as spam (code 368) or hits a rate limit, Kreatix does not retry: retrying makes the block worse.
- Kreatix posts to the Facebook Pages you manage.
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 Facebook from ChatGPT?
Connect ChatGPT to Kreatix once, as shown above. Then ask it to post: name your Facebook pages or a page group, the video or text and the time. ChatGPT shows you the plan and posts after you say yes.
Can the agent post text without a video to Facebook?
Yes. Leave media_url out and the caption goes out as a Page post. Facebook, LinkedIn and X are the networks that take text-only posts.
Does a Facebook video go out as a Reel or a regular video?
As a Reel. Kreatix uploads it through Facebook's Reels flow and, if you gave a cover, sets it once Facebook has finished processing the video.
What if Facebook blocks the post as spam?
Kreatix does not send it again on its own, because repeating is what Facebook's block (code 368) punishes. The post shows as failed with Facebook's reason, and the fix is to wait.
Can my agent post to 20 Facebook Pages at once?
Yes: up to 50 pages in one schedule_post call, or a whole group with group_id. Each page counts as one post toward the key's hourly limit, 100 an hour by default.
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.
