It is not the same as Claude Code (the terminal agent) or the Postiz connector in Claude.ai; read the full comparison on the Claude Cowork hub.

How do YouTube workflows run in Claude Cowork?

Two ways: ask Cowork directly in the desktop app, where it can read the content from your local files, or set up a scheduled task that runs in the cloud on a timetable you choose.

From your desktop files

Local folders, Google Drive, no terminal

Point Claude Cowork at a document or media file on your computer and tell it where and when to upload. It reads the file, uploads media through Postiz, applies the YouTube settings, and schedules the result for your YouTube channel.

Claude Cowork

You: Upload ~/Videos/demo.mp4 to YouTube
  as public tomorrow at noon, title
  "Postiz in 3 minutes", thumbnail thumb.png

Claude Cowork: Uploading demo.mp4 via Postiz...
  1. Video uploaded (212 MB)
  2. Thumbnail uploaded
  3. Scheduled public upload for 12:00 PM

  Done! Want tags added as well?

Scheduled tasks

Recurring YouTube videos without a cron server

Type /schedule in any Cowork task to make it recurring. Scheduled tasks run in the cloud with the connectors you have set up, so your computer does not need to be awake for Cowork to upload to YouTube on time.

Claude Cowork scheduled task

/schedule

"Every Thursday at 4pm, upload the newest file in ~/Videos/ready to YouTube as unlisted with a title from its filename, then message me the link."

Claude Cowork will, on each run:
  1. Read the source file or folder
  2. Draft the YouTube content
  3. Schedule it through Postiz
  4. Report back what it did

Why Claude Cowork + Postiz for YouTube

✓No terminal: Postiz is a connector in the Claude app, added once
✓Reads YouTube videos content from local folders and connected apps like Google Drive
✓Scheduled tasks run in the cloud on a timetable you set
✓Cross-posts YouTube content to other Postiz channels in one request
✓Uses the same Postiz account, channels, and calendar as your dashboard and other agents

Also Works with OpenClaw

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes OpenClaw, the open-source personal AI agent, which reads the Postiz skill and runs the CLI rather than connecting over MCP.

🦀

OpenClaw

Open-source AI agent

OpenClaw reads the Postiz skill so it knows what it can do, then autonomously discovers your YouTube integration, uploads your video and thumbnail, applies tags and visibility settings, and schedules the upload.

OpenClaw

> Upload my tutorial video to YouTube
  as public with tags "coding" and
  "tutorial", schedule for tomorrow

OpenClaw: Done! Scheduled on YouTube for
  tomorrow at 9:00 AM.

YouTube + Other Platforms

Schedule the same video to YouTube and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  YouTube and LinkedIn tomorrow at 9am, then schedule
  a daily tip on YouTube every weekday at 10am

Claude Cowork: Done! Scheduled:
  - YouTube + LinkedIn: tomorrow 9:00 AM
  - Daily tips on YouTube: Mon-Fri 10:00 AM

What should you know before posting to YouTube from Claude Cowork?

Cowork handles these rules for you, but knowing them explains why it sometimes asks a follow-up question before scheduling.

✓title is required and must be 2 to 100 characters; type must be public, unlisted, or private.
✓Custom thumbnails are uploaded separately and referenced by id and path. Ask Cowork to include the thumbnail file.
✓YouTube requires a made-for-kids declaration; set selfDeclaredMadeForKids to yes or no when your channel needs it.

Claude Cowork and YouTube: frequently asked questions

How do I upload a YouTube video from Claude Cowork?

Add Postiz as a custom connector in Cowork (Customize, then Connectors, URL https://mcp.postiz.com/mcp-oauth-dynamic), sign in, and tell Cowork which video file to upload, the title, and when to publish. Cowork uploads the file through Postiz and schedules it. No terminal, API key, or YouTube Studio visit is needed.

Can Claude Cowork set a custom YouTube thumbnail?

Yes. Name the image file and Cowork uploads it through Postiz, then passes its id and path in the thumbnail setting when it creates the upload. YouTube applies it once the video publishes. Thumbnails should be 1280 by 720 pixels or larger for the best result.

Can Cowork schedule an unlisted or private YouTube upload?

Yes. The type setting accepts public, unlisted, or private, so you can ask Cowork to upload a video as unlisted for review and later ask it to change visibility. This is useful for sharing a draft with teammates before the public launch.

What is the difference between Claude Cowork and Claude Code for YouTube uploads?

Both use the same Postiz YouTube channel and settings. Claude Code is the terminal agent and connects with a claude mcp add command or the Postiz CLI. Claude Cowork is the desktop agent, so you add Postiz as a connector and can pick the video straight from a local folder.

Can Claude Cowork turn a long YouTube video into shorts?

Yes, when Postiz is added through the custom MCP link. Postiz includes clipping tools that cut a long video into vertical short clips with captions, which Cowork can then schedule to YouTube, TikTok, or Instagram. The official directory connector does not include the clipping tools.
