https://api.kreatix.cc/mcp/YOUR_KEYWhat Claude 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 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."
- 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 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 Pinterest from Claude?
Connect Claude 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. Claude 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.
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.
