Post to TikTok from Grok
Grok is the AI assistant at grok.com and in the Grok apps. Connectors let it use outside services, and a custom connector adds your own MCP server, such as Kreatix. A video with your caption, shared with the privacy you choose; TikTok takes no text-only post.

https://api.kreatix.cc/mcp/YOUR_KEYWhat Grok can do on TikTok
A video with your caption, shared with the privacy you choose; TikTok takes no text-only post.
| Setting | Values | Needed | What it does |
|---|---|---|---|
media_url | URL | Yes | The video: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post, which Kreatix imports first. |
tiktok_privacy | PUBLIC_TO_EVERYONE, MUTUAL_FOLLOW_FRIENDS, FOLLOWER_OF_CREATOR, SELF_ONLY | Yes | Who can see the video: everyone, friends, followers or only you (private), in that order. There is no default, so the agent has to ask you. |
tiktok_music_confirmed | true | Yes | Set to true once you agree to TikTok's Music Usage Confirmation. Without it, the TikTok post is refused. |
caption | string (max 5000) | No | The video's text on TikTok. Only the first 2,200 characters go. |
Ask in plain words
A chat message at grok.com. For example: "Which of my pages got the most views this week?" Grok calls Kreatix when the question is about your pages.
- Post my newest video on both TikTok pages tomorrow at 19:00, public. I agree to TikTok's music terms.
- Take this YouTube Shorts link and post it on TikTok tonight at 21:00, followers only.
- Move Saturday's TikTok post to Sunday 12:00.
TikTok rules to know
- Kreatix never picks a privacy level for you: a TikTok post without your choice is refused.
- You must agree to TikTok's Music Usage Confirmation, or the TikTok post is refused.
- TikTok refuses videos whose average frame rate is outside 23 to 60 fps, so Kreatix sends it a 30 fps copy and keeps your original.
- Only the first 2,200 characters of the caption go to TikTok.
- The agent schedules videos only; TikTok photo posts go from Kreatix's Publish now to your TikTok inbox.
Tips for Grok
- Grok reaches Kreatix from its own servers over the internet, so nothing has to run on your computer.
- After you connect, Grok discovers Kreatix's seven tools by itself. Ask in plain words; you don't need tool names.
- 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 TikTok from Grok?
Connect Grok to Kreatix once, as shown above. Then ask it to post: name your TikTok pages or a page group, the video or text and the time. Grok shows you the plan and posts after you say yes.
Why does the agent ask me about privacy every time?
TikTok's rule for apps that post for you: the person picks who can see each video, and there is no default. Kreatix never picks Public for you, so a TikTok post without your choice is refused.
Can I post a YouTube Short to TikTok?
Yes. Give the agent the public link: Kreatix downloads the video into your library first (from YouTube, the best version up to 1080p), then schedules it on TikTok. If the download fails, the agent says so and nothing is scheduled.
My video was shot at a low frame rate. Will TikTok take it?
TikTok refuses videos whose average frame rate is outside 23 to 60 fps. Kreatix checks the file and sends TikTok a 30 fps copy; your original stays as it is.
Can the agent turn off comments, duets or stitches?
No. schedule_post sends TikTok only your privacy choice. The comment, duet and stitch switches, branded content and the AI label are set on Kreatix's Publish screen.
Do I need a paid Grok plan?
Grok's docs say connectors are available to all Grok users. On Grok Business and Enterprise, a team admin first provisions the connector in the cloud console. Scheduling posts still needs a paid Kreatix plan or a running trial.
I made a new Kreatix key. How do I update Grok?
On the key route, the key is part of the address. Remove the Kreatix connector in Grok and add it again with the new address, 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.
