Post to LinkedIn 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 text-only post or a video with text, published publicly on your own LinkedIn profile.

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 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 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 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 LinkedIn from Grok?
Connect Grok 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. Grok 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.
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.
