https://api.kreatix.cc/mcp/YOUR_KEYWhat ChatGPT can do on LinkedIn
A text-only post or a video with text, published publicly on your own LinkedIn profile.
| Setting | Values | Needed | What it does |
|---|---|---|---|
caption | string (max 5000) | No | The post text. A text-only post needs it. |
media_url | URL | No | One video to post with the text: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post. Leave it out for a text-only post. |
Ask in plain words
A chat message on chatgpt.com. Type @, pick Kreatix and ask, for example: "@Kreatix which of my pages got the most views this week?"
- Post this on my LinkedIn tomorrow at 8:30: We hired our first two engineers this month.
- Share yesterday's product video on LinkedIn at 12:00 with a short, plain caption.
- What is planned on my LinkedIn next week?
LinkedIn rules to know
- Posts go out on the profile of the person who connected LinkedIn, in their name.
- Every post is public: Kreatix sends LinkedIn the PUBLIC visibility.
- A text-only post needs a caption.
- get_stats has no numbers for LinkedIn.
Tips for ChatGPT
- Pick Kreatix with @ in the prompt box. If ChatGPT reaches for web search instead, say "use only Kreatix" or name the tool, such as get_stats.
- ChatGPT asks you to confirm before it schedules, moves or cancels a post. You can remember your answer for one conversation; a new conversation asks again.
- When Kreatix adds new tools, open the plugin at chatgpt.com/plugins and select Refresh.
- 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 LinkedIn from ChatGPT?
Connect ChatGPT to Kreatix once, as shown above. Then ask it to post: name your LinkedIn pages or a page group, the video or text and the time. ChatGPT shows you the plan and posts after you say yes.
Can it post to a LinkedIn company page?
Kreatix posts as the person who connected LinkedIn, on their own profile. Company pages are not part of the connection.
Who can see the post?
Everyone: Kreatix publishes LinkedIn posts with public visibility.
Can the agent post text only?
Yes. LinkedIn, X and Facebook take text-only posts. Leave media_url out and give a caption.
What if my LinkedIn login expires?
list_channels shows needs_reconnect on that channel, and nothing goes out there until you reconnect it in Kreatix. A post still waiting 24 hours after its time is marked failed, and Kreatix tells you.
Will ChatGPT post without asking me?
No. ChatGPT treats scheduling, moving and cancelling as write actions and asks you to confirm each one. Reading your pages, queue and stats runs without a prompt, because Kreatix marks those tools read-only.
Can I give ChatGPT my key in a header?
No. ChatGPT can't send custom API keys. Use Sign in with Kreatix (OAuth), or paste the address with the key in it and choose No authentication.
Kreatix schedules one video to every page you run, each with its own platform settings.
