Post to YouTube 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 a title, a description and the visibility you choose; YouTube takes no text-only post.

https://api.kreatix.cc/mcp/YOUR_KEYWhat Grok can do on YouTube
A video with a title, a description and the visibility you choose; YouTube 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. |
youtube_title | string (max 100) | No | The title, up to 100 characters. Without it, Kreatix makes one from the caption's first line, minus hashtags and @mentions. |
youtube_privacy | public, unlisted, private | No | Who can see the video. Left out, the video goes up public. |
caption | string (max 5000) | No | Becomes the video description, cut at 5,000 bytes, and the source of the title when youtube_title is empty. |
cover_url | URL | No | Set as the video's custom thumbnail right after the upload. If YouTube refuses it, the video stays up without it. |
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.
- Put this video on my YouTube channel Friday at 17:00 as unlisted. Title: How we pack 500 orders a day.
- Post my newest TikTok video to YouTube tonight at 20:00 with a clear title.
- How many views did my YouTube channel get in the last 30 days, compared with the month before?
YouTube rules to know
- A title of your own takes at most 100 characters; without one, Kreatix uses the caption's first line minus hashtags and @mentions.
- YouTube does not take < and >, so Kreatix sends them as ‹ and ›.
- Leave youtube_privacy out and the video goes up public.
- Scheduled videos go up marked as not made for kids.
- If YouTube says an upload limit is reached, Kreatix moves the post 6 hours later, up to 5 times, then marks it failed.
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 YouTube from Grok?
Connect Grok to Kreatix once, as shown above. Then ask it to post: name your YouTube pages or a page group, the video or text and the time. Grok shows you the plan and posts after you say yes.
What title will my video get?
The youtube_title you give, up to 100 characters. Without one, Kreatix takes the caption's first line, drops hashtags and @mentions and fits it into 100 characters. With no caption at all, the title is Untitled.
Can I upload as private or unlisted?
Yes. Set youtube_privacy to public, unlisted or private. Left out, the video goes up public.
What happens when YouTube's upload limit is hit?
Kreatix does not drop the post: it moves it 6 hours later and tries again, up to 5 times. After that the post shows as failed, so you see it.
Does the cover I pick show on YouTube?
Kreatix sets cover_url as the custom thumbnail right after the upload. If YouTube refuses it, for example when the channel can't use custom thumbnails yet, the video stays up and only the thumbnail is skipped.
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.
