Post to Instagram from Claude
Claude is Anthropic's AI assistant on claude.ai and in the Claude Desktop app. Custom connectors let it use outside tools such as Kreatix inside a normal chat. 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 Claude 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 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 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 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 Instagram from Claude?
Connect Claude 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. Claude 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.
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.
