What is Claude Code?

Claude Code is Anthropic's agentic coding tool that lives in your terminal. It handles software engineering tasks — writing features, fixing bugs, and answering questions about your codebase — and it can run shell commands and MCP tools like Postiz.

Not the same as Claude Cowork (Anthropic's desktop agent for knowledge workers) or the Postiz connector for Claude.ai (chat in the browser or desktop app). Claude Code runs in your terminal and IDE and can read your repository while it writes Dev.to posts.

💻

Terminal & IDE Native

Claude Code runs in your terminal, with extensions for VS Code and JetBrains. You type what you want in plain English and it handles Postiz for you.

🔧

Agentic Execution

Claude Code plans and works through multi-step tasks on its own — discovering channels, uploading media, and scheduling posts — and asks for permission before it acts.

⚡

Parallel Tasks

Run several Claude Code sessions side by side, or spawn subagents in one. Schedule posts to different platforms while it handles other coding work.

How Postiz Works with Claude Code

Claude Code discovers Postiz through the Postiz skill or the Postiz MCP server. It reads the SKILL.md (or the MCP tool list) to learn what it can do, then chains calls together for social media workflows.to articles with the right settings.

✓Install the Postiz skill, or add the Postiz MCP server with claude mcp add
✓Claude Code discovers the Postiz tools over MCP, or reads SKILL.md when you use the skill
✓MCP route: sign in with OAuth, no API key. Skill route: set POSTIZ_API_KEY
✓Claude Code asks for permission before running commands
✓Works alongside your coding tasks in parallel

Install Postiz

# Option A: add the Postiz MCP server
claude mcp add --transport http postiz https://mcp.postiz.com/mcp-oauth-dynamic

# Option B: install the Postiz skill
npx skills add gitroomhq/postiz-agent
export POSTIZ_API_KEY=your_api_key

# Then just ask
claude "list my social media integrations"

Dev.to Publishing with Claude Code

Tell Claude Code what to post from your terminal or IDE — it discovers your integrations via Postiz and handles the entire publishing workflow.to integration, and handles the entire publishing workflow autonomously.

Multiple tasks at once

Claude Code runs headless with claude -p, so several tasks can run in parallel. Schedule posts to different platforms while it works on other coding tasks.to automatically — no manual trigger needed.

Claude Code Parallel Tasks

# Run multiple posting tasks in parallel
$ claude -p "Schedule a post about our
  launch to X for tomorrow 9am" &

$ claude -p "Write a LinkedIn article
  about our new feature and schedule
  for tomorrow noon" &

$ claude -p "Fix the bug in auth.ts"

# All three tasks run simultaneously

Why Claude Code + Postiz for Dev.to

Claude Code's autonomous execution makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Dev.to workflows.

✓Runs in your terminal or IDE — just type what you want
✓Permission-based execution — you stay in control
✓Parallel task support — post while coding
✓Cover images uploaded and attached automatically
✓Cross-post to Dev.to + other platforms in a single session

Dev.to and Claude Code: frequently asked questions

How do I publish to Dev.to from Claude Code?

Add the Postiz MCP server to Claude Code, sign in to Postiz with OAuth, and connect your Dev.to account in Postiz. Then point Claude Code at a markdown file and mention the tags and cover image. It uploads the cover, fills the Dev.to settings, asks for permission, and publishes or schedules the article.

How many tags can Claude Code add to a Dev.to article?

Up to four. Name the tags you want and Claude Code passes them as value and label pairs. If you ask for more than four, it keeps the four most relevant and tells you which ones it dropped. Tags help the article land in the right Dev.to topic feeds.

Can Claude Code publish to a Dev.to organization?

Yes. Ask Claude Code to publish under your organization and it sets the organization field with the ID from Postiz. If you belong to several, ask it to list them first. Without an organization, the article is published under your personal Dev.to profile.

Can Claude Code syndicate my blog to Dev.to with a canonical URL?

Yes. Mention the original URL and Claude Code sets canonical so Dev.to credits your blog as the source. Combine it with a cover image and tags and you have a complete cross-post. Headless mode, claude -p, lets you run this from a publish hook whenever a new blog post ships.
