Post to LinkedIn from Cursor

Connect Cursor to Kreatix

Sign in with Kreatix

No key to copy: paste the address, sign in to Kreatix and press Allow.

Open ~/.cursor/mcp.json (create the file if it isn't there) and add Kreatix with only its url, as in the snippet.
Save the file and restart Cursor.
Follow Cursor's sign-in prompt for kreatix, or run agent mcp login kreatix with the Cursor CLI. Sign in to Kreatix and press Allow.
Open Customize > MCPs in the sidebar and check that kreatix is on.

{
  "mcpServers": {
    "kreatix": {
      "url": "https://api.kreatix.cc/mcp"
    }
  }
}

With a key

For setups without sign-in. The key works like a password, so keep it to yourself.

In Kreatix, open Settings > AI agent and create a key. It is shown once.
Add Kreatix with its url and an Authorization header to ~/.cursor/mcp.json (create the file if it isn't there), as in the snippet.
Save the file and restart Cursor.
Open Customize > MCPs in the sidebar and check that kreatix is on.

{
  "mcpServers": {
    "kreatix": {
      "url": "https://api.kreatix.cc/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_KEY"
      }
    }
  }
}

What Cursor 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

Ask in Cursor's agent chat, for example "Use Kreatix to move tonight's posts on my brand group to 21:00." From a terminal, the Cursor CLI takes one-off prompts: agent -p "Which of my Kreatix 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 Cursor

Put Kreatix in ~/.cursor/mcp.json, not in a project's .cursor/mcp.json: project files are meant to be committed and shared with your team.
To keep the key out of the file, write "Authorization": "Bearer ${env:KREATIX_API_KEY}". Cursor fills in ${env:NAME} in url and headers.
Cursor asks before each MCP tool call. Click the arrow next to the tool name to check the pages, caption and time before you approve.
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 Cursor?

Connect Cursor 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. Cursor 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.

How do I know Kreatix connected?

Open Customize > MCPs in the sidebar and look for kreatix with its toggle on. If it is missing, open the Output panel (Cmd+Shift+U on Mac), choose MCP Logs and look for an error.

Does the Cursor CLI need its own setup?

No. The CLI reads the same mcp.json as the editor. Run agent mcp list to see kreatix.

Kreatix schedules one video to every page you run, each with its own platform settings.
