Postiz is the agentic social media scheduling platform that Claude Cowork drives through an MCP connector and the Postiz CLI. Please make sure there is always a human in the loop. Part of the Postiz AI agents guide.

How do you connect Postiz to Claude Cowork?

Add Postiz as a custom connector in Cowork. It takes about three minutes, needs no terminal, and uses OAuth instead of an API key. After that, you just ask.

1Connect
about three minutes

Add Postiz as a connector

One custom connector in the Claude desktop app links Cowork to every channel through Postiz. Sign in once with OAuth.

Cowork > Customize > Connectors
# Cowork tab > Customize > Connectors > + Add custom connector
Name: Postiz
URL:  https://mcp.postiz.com/mcp-oauth-dynamic
# Sign in to Postiz and approve access. No API key.

Copy grabs the MCP link. Already added Postiz in Claude.ai? The official directory connector works in Cowork too, without the media tools. Details on the Postiz MCP page.

2Ask
live in Postiz

Ask Cowork to post for you

Once connected, Cowork calls Postiz tools: it uploads media, applies platform settings and schedules. Posts go out on time even after you close the app.

Post my blog article to X, LinkedIn and Reddit with the cover image, scheduled for tomorrow at 9am.

Claude Cowork

Done. I found your channels through Postiz, uploaded the cover image and scheduled all three for 9:00 tomorrow. Reddit goes to r/programming as a text post. Want me to add a daily tip for the rest of the week?

What is Claude Cowork?

Claude Cowork is Anthropic's agentic assistant for knowledge workers. It uses the same agentic architecture as Claude Code with no terminal, runs in the Claude desktop app on macOS and Windows (and on the web) for paid Claude plans, and can read local files, use connectors and plugins, run multi-step tasks, and schedule recurring tasks in the cloud. With Postiz connected, one of those tasks is running your social media.

Desktop Native

Claude Cowork runs directly on your desktop, connecting to your local files and apps. No dashboard tabs or terminal needed to manage your social media workflow.

App Integrations

Connects to Google Drive, Gmail, DocuSign, and more. Pull content from your existing tools and publish it to social media seamlessly.

Autonomous Tasks

Claude Cowork completes multi-step tasks on its own. Tell it to draft, schedule, and publish posts — it handles the entire workflow.

How Postiz Works with Claude Cowork

Postiz is an MCP server, and Claude Cowork supports custom connectors over remote MCP. Add the Postiz link once in Customize, then Connectors, sign in with OAuth, and Cowork sees the Postiz tools for listing channels, uploading media, scheduling posts, and reading analytics.

  • Open the Cowork tab, then Customize, then Connectors, and add a custom connector named Postiz
  • Paste the Postiz MCP link and sign in to Postiz when prompted (OAuth, no API key)
  • Cowork discovers the Postiz tools and your connected channels automatically
  • Ask in plain language; Cowork chains upload, settings, and scheduling steps for you
  • Prefer the Postiz skill and CLI? Add the gitroomhq/postiz-agent plugin instead and run postiz auth:login
Connect Postiz to Claude Cowork
# Option 1: custom connector (recommended, full toolset)
Cowork > Customize > Connectors > +
  Name: Postiz
  URL:  https://mcp.postiz.com/mcp-oauth-dynamic
  Sign in to Postiz and approve

# Option 2: official connector (posting + scheduling)
claude.ai/directory/postiz > Connect

# Option 3: Postiz skill + CLI (terminal)
npm install -g postiz
postiz auth:login

How do social media workflows run in Claude Cowork?

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

Desktop Workflow

No terminal needed

Tell Claude Cowork what to post from your desktop. It connects to Postiz, discovers your accounts, uploads media, and schedules posts — all while you go about your day.

Claude Cowork
You: Post my blog article to Twitter,
  LinkedIn, and Reddit with the cover
  image, schedule for tomorrow at 9am

Claude Cowork: I'll handle that.
  1. Found your integrations via Postiz
  2. Uploading cover image
  3. Scheduling across 3 platforms

  Done! Posts scheduled:
  - X (Twitter): scheduled 9:00 AM
  - LinkedIn: scheduled 9:00 AM
  - Reddit (r/programming): scheduled 9:00 AM

Scheduled Tasks

Recurring posts 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 post on time.

Claude Cowork scheduled task
/schedule

"Every weekday at 8am, check my
~/Content/drafts folder for new posts
and schedule them to all my social
platforms for noon today. Move
published drafts to ~/Content/published."

Claude Cowork will, on each run:
  1. Read the drafts folder
  2. Format each post per platform
  3. Schedule via Postiz
  4. Move files and report back

Why Claude Cowork + Postiz

  • No terminal: Postiz is a connector in the Claude app, added once
  • Reads post content from local folders and connected apps like Google Drive
  • Multi-step autonomy: discovery, media upload, settings, and scheduling in one request
  • Scheduled tasks run in the cloud on a timetable you set
  • Cross-posts to multiple platforms with per-platform settings
  • 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. It autonomously discovers your integrations, uploads media, composes posts with platform-specific settings, and schedules content across all your connected platforms.

Claude Cowork and Postiz: frequently asked questions

How do I connect Postiz to Claude Cowork?

Open the Claude desktop app, switch to the Cowork tab, and go to Customize, then Connectors. Click the plus button, name the connector Postiz, paste https://mcp.postiz.com/mcp-oauth-dynamic, and sign in to Postiz when prompted. Cowork then lists your connected channels and can schedule posts. No terminal or API key is involved.

Is Claude Cowork the same as Claude Code?

No. Both are Anthropic agents built on the same agentic architecture, but Claude Code runs in a terminal and is aimed at developers, while Claude Cowork runs in the Claude desktop app for knowledge workers with no terminal. Postiz supports both: Cowork through a connector, Claude Code through a claude mcp add command or the Postiz CLI.

Is Claude Cowork the same as the Postiz connector in Claude.ai?

Not quite. The official Postiz connector in the Claude directory works in Claude.ai chat and covers posting, scheduling, and analytics. Claude Cowork is the desktop agent that can also read your local files and run scheduled tasks, and adding Postiz through the custom MCP link gives it the full toolset including image, video, and clipping tools.

Do I need an API key or a terminal to use Postiz with Cowork?

No. Adding Postiz as a connector authenticates through OAuth, so you sign in to Postiz once and approve access. Nothing is installed and no key is pasted anywhere. The Postiz CLI and API key are only needed if you deliberately choose the skill-and-CLI route, which is more common with Claude Code.

Can Claude Cowork post to social media on a schedule automatically?

Yes, in two ways. Every Postiz post has a publish time, so Cowork can queue a week of content in one request. For recurring work, type /schedule in a Cowork task and it runs in the cloud on the timetable you set, using your connectors, so your computer does not need to be awake.

Which social media platforms can Claude Cowork post to?

Every channel Postiz supports, which is 30 or more including X, LinkedIn, Instagram, Facebook, Reddit, YouTube, TikTok, Pinterest, Threads, Bluesky, Mastodon, Discord, Slack, Telegram, and more. This site has dedicated Claude Cowork guides for 25 of them, each with example prompts, the platform settings Cowork can apply, and platform-specific FAQs.

What does it cost to use Postiz with Claude Cowork?

Claude Cowork is included in Anthropic's paid Claude plans on the desktop app. Postiz offers a 7-day free trial, and paid plans start at $29 per month. There is no extra charge for connecting the two or per post scheduled; see the Postiz pricing page for current plan limits.

Can Claude Cowork generate images or videos for my posts?

Yes, when Postiz is added through the custom MCP link, which includes Postiz image generation, video generation, and video clipping tools. Ask Cowork for a cover image or to cut a long video into shorts, then have it schedule the result. The official directory connector does not include these media tools.

Why does Cowork ask me a question before it posts?

Some platforms require settings Postiz cannot guess: Reddit needs a title and sometimes a flair, X needs a reply-control choice, YouTube needs a visibility level, TikTok needs privacy and interaction flags. Cowork checks the channel schema first and asks only for what is missing, then confirms the final settings before scheduling.

Is it safe to let an AI agent post to my accounts?

Keep a human in the loop. Cowork shows what it will schedule before it acts, and you can ask it to create drafts for review instead of scheduling. Access is granted through OAuth and can be revoked from Postiz or from Claude connector settings at any time, and your social passwords are never shared with Cowork or Postiz.
