How do Medium 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 publish. It reads the file, uploads media through Postiz, applies the Medium settings, and schedules the result for your Medium account.

Claude Cowork

You: Publish ~/Writing/mcp-guide.md on
  Medium tomorrow at 9am, subtitle
  "A practical walkthrough", tags AI, MCP

Claude Cowork: Reading mcp-guide.md...
  1. Title and subtitle set
  2. Tags: AI, MCP
  3. Scheduled for 9:00 AM

  Done! Add a canonical URL to your blog?

Scheduled tasks

Recurring Medium articles 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 publish to Medium on time.

Claude Cowork scheduled task

/schedule

"Every Tuesday at 9am, publish the oldest draft in ~/Writing/ready to Medium with a subtitle and up to 4 tags, then move it to ~/Writing/published."

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

Why Claude Cowork + Postiz for Medium

Cowork brings the desktop context and the scheduling; Postiz brings the Medium publishing, media handling, and analytics. Together they replace a scheduler dashboard with a conversation.

✓Reads Medium articles content from local folders and connected apps like Google Drive
✓Scheduled tasks run in the cloud on a timetable you set
✓Cross-posts Medium 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

  under the engineering publication with
  a canonical URL back to my blog

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

Medium + Other Platforms

Claude Cowork and Medium: frequently asked questions

How do I publish to Medium from Claude Cowork?

Add Postiz as a custom connector in Cowork (Customize, then Connectors, URL https://mcp.postiz.com/mcp-oauth-dynamic), sign in to Postiz, and ask Cowork to publish a draft from your desktop. It fills the title, subtitle, and tags and schedules the article through Postiz. No terminal or API token is needed.

Can Claude Cowork set a canonical URL on Medium?

Yes. Say the article was first published on your site and give the URL. Cowork sets the canonical field when it creates the Medium post through Postiz, so Medium tells search engines the original lives on your domain and your SEO is not split between two copies.

Can Cowork publish to a Medium publication?

Yes. Name the publication and Cowork resolves its ID and sets the publication field. The article is submitted to that publication according to your role there; editors may still need to approve it inside Medium depending on the publication's settings.

Is this different from publishing to Medium with Claude Code?

The Postiz settings are identical. Claude Code is Anthropic's terminal agent and connects with a claude mcp add command or the Postiz CLI. Claude Cowork is the desktop agent, so Postiz is added as a connector and Cowork can read the draft from a local Markdown or Word file.

Up to four. Cowork accepts the tags you name and drops or asks about extras. Medium uses tags for topic distribution, so choose ones your readers follow. Cowork can also suggest tags based on the draft if you ask it to.
