Post to YouTube from Cursor

Cursor is an AI code editor with a built-in agent, plus a command line agent. Developers use it to write code, and its agent can call MCP tools such as Kreatix. A video with a title, a description and the visibility you choose; YouTube takes no text-only post.

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 YouTube

A video with a title, a description and the visibility you choose; YouTube takes no text-only post.

Setting	Values	Needed	What it does
`media_url`	URL	Yes	The video: a link from your Kreatix library or a public YouTube, TikTok, Instagram or Facebook post, which Kreatix imports first.
`youtube_title`	string (max 100)	No	The title, up to 100 characters. Without it, Kreatix makes one from the caption's first line, minus hashtags and @mentions.
`youtube_privacy`	public, unlisted, private	No	Who can see the video. Left out, the video goes up public.
`caption`	string (max 5000)	No	Becomes the video description, cut at 5,000 bytes, and the source of the title when youtube_title is empty.
`cover_url`	URL	No	Set as the video's custom thumbnail right after the upload. If YouTube refuses it, the video stays up without it.

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?"

Put this video on my YouTube channel Friday at 17:00 as unlisted. Title: How we pack 500 orders a day.
Post my newest TikTok video to YouTube tonight at 20:00 with a clear title.
How many views did my YouTube channel get in the last 30 days, compared with the month before?

YouTube rules to know

A title of your own takes at most 100 characters; without one, Kreatix uses the caption's first line minus hashtags and @mentions.
YouTube does not take < and >, so Kreatix sends them as ‹ and ›.
Leave youtube_privacy out and the video goes up public.
Scheduled videos go up marked as not made for kids.
If YouTube says an upload limit is reached, Kreatix moves the post 6 hours later, up to 5 times, then marks it failed.

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 YouTube from Cursor?

Connect Cursor to Kreatix once, as shown above. Then ask it to post: name your YouTube pages or a page group, the video or text and the time. Cursor shows you the plan and posts after you say yes.

What title will my video get?

The youtube_title you give, up to 100 characters. Without one, Kreatix takes the caption's first line, drops hashtags and @mentions and fits it into 100 characters. With no caption at all, the title is Untitled.

Can I upload as private or unlisted?

Yes. Set youtube_privacy to public, unlisted or private. Left out, the video goes up public.

What happens when YouTube's upload limit is hit?

Kreatix does not drop the post: it moves it 6 hours later and tries again, up to 5 times. After that the post shows as failed, so you see it.

Does the cover I pick show on YouTube?

Kreatix sets cover_url as the custom thumbnail right after the upload. If YouTube refuses it, for example when the channel can't use custom thumbnails yet, the video stays up and only the thumbnail is skipped.

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.
