Post to Pinterest 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 pin with a cover picture, on one of your boards.

https://api.kreatix.cc/mcp/YOUR_KEYWhat Grok can do on Pinterest
A video pin with a cover picture, on one of your boards.
| Setting | Values | Needed | What it does |
|---|---|---|---|
media_url | URL | Yes | The pin's video: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post, which Kreatix imports first. |
cover_url | URL | Yes | The pin's cover, a picture stored in Kreatix. With an imported link and no cover, Kreatix uses the link's thumbnail; a link without one is refused. |
caption | string (max 5000) | No | The first 100 characters become the pin title and the first 800 the description. |
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.
- Pin my newest video to Pinterest tomorrow at 20:00 with the cover it already has.
- Post this YouTube link to my Pinterest at noon.
- Move the Pinterest post planned for Saturday to Sunday 11:00.
Pinterest rules to know
- A Pinterest video needs a cover picture, or schedule_post refuses it.
- With an imported link, the link's thumbnail becomes the cover; a link without one is refused for Pinterest.
- The pin title is the caption's first 100 characters and the description its first 800.
- The pin goes to the first board Pinterest lists; with no board, Kreatix creates one named Kreatix.
- Pinterest takes no text-only post, and get_stats has no numbers for it.
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 Pinterest from Grok?
Connect Grok to Kreatix once, as shown above. Then ask it to post: name your Pinterest 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 my Pinterest video need a cover?
Pinterest refuses a video pin without one, and the refusal reads like a broken login. Kreatix asks for cover_url up front, or takes the thumbnail of a link it imports.
Which board does the pin go to?
The first board Pinterest lists for the account. If the account has no board, Kreatix creates one named Kreatix. The agent can't pick a board.
How long can the caption be?
Up to the tool's 5,000 characters, but Pinterest gets the first 100 as the title and the first 800 as the description.
Can my agent see how my pins perform?
No. get_stats measures Instagram, Facebook, TikTok and YouTube; Pinterest has no numbers in Kreatix.
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.
