https://api.kreatix.cc/mcp/YOUR_KEYWhat Claude 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 normal chat message in claude.ai or Claude Desktop, with Kreatix turned on under + > Connectors. For example: "Post this TikTok link to all my Instagram pages tomorrow at 18:00."
- 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 Claude
- Turn Kreatix on per chat under + > Connectors, and leave it off in chats that shouldn't touch your pages.
- One setup covers claude.ai and Claude Desktop, because connectors live in your Claude account. Claude Code sees it too when it is logged in with the same claude.ai account.
- Give Allow always only to the reading tools (list_channels, list_groups, list_posts, get_stats). Keep scheduling on ask, so you see the pages, caption and time first.
- 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 Claude?
Connect Claude 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. Claude 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.
Does it work on the free Claude plan?
Yes. Custom connectors work on Free, Pro, Max, Ultra, Team and Enterprise, and the Free plan allows one custom connector. On Team and Enterprise, an Owner first adds Kreatix under Organization settings > Connectors, then each member clicks Connect.
Can I switch from the key address to Sign in with Kreatix later?
Yes, but Claude can't change a connector's sign-in settings after you add it. Remove the connector, add it again with https://api.kreatix.cc/mcp, 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.
