Hashnode-Specific Features

📖

Blog Publishing

Publish long-form blog posts with full Markdown support. Code blocks, embeds, and rich formatting work out of the box.

📚

Publication Support

Publish posts under your Hashnode publication. Every post requires a publication ID to target the right blog.

🖼

Cover Images

Upload and attach cover images to make your posts stand out. Eye-catching visuals drive more clicks from the Hashnode feed.

🔗

Canonical URLs

Set canonical URLs for SEO when cross-posting from your original blog. Avoid duplicate content penalties across platforms.

🏷

Required Tagging

Hashnode requires at least one tag per post. Tags use tag IDs for precise categorization and improved discoverability.

📅

Scheduled Publishing

Schedule blog posts for future publication with precise timestamps. Build a consistent publishing cadence effortlessly.

How It Works

You describe what you want in plain language and Claude Code handles the Postiz calls for you. Here is how a typical conversation goes.

Find Your Hashnode Integration

Ask Claude Code whether your Hashnode account is connected. It also checks which options the platform supports.

Example conversation

> Is my Hashnode account connected to Postiz?

Claude Code: Yes — your Hashnode account is connected
  and ready. Want me to post something?

Prepare Your Content

Write your blog post in Markdown. Hashnode supports rich formatting including headers, code blocks with syntax highlighting, images, and embedded content. Optionally upload a cover image.

Example conversation

> Draft a Hashnode post about our new
  feature launch

Claude Code: Here's a draft for Hashnode:
  "We just shipped something big..."
  Want me to add media and schedule it?

Publish Your Post

Create a post with your content, title, publication, tags, and optional cover image and canonical URL. Remember: publication and at least one tag are required.

Example conversation

> Yes — add screenshot.png and schedule
  it for tomorrow at 9am

Claude Code: Done! Scheduled on Hashnode for
  tomorrow at 9:00 AM.

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.

💻

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.

✓Install the Postiz skill, or add the Postiz MCP server with claude mcp add
✓Claude Code reads the SKILL.md and learns all Postiz commands
✓POSTIZ_API_KEY must be set in environment
✓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"

Hashnode 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.

💻

Just Ask Claude Code

Terminal and IDE integration

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

Claude Code CLI

$ claude "Post to Hashnode about our
  new feature launch, schedule for
  tomorrow at 9am"

Claude Code: I'll handle that.
  Found your Hashnode integration.
  Composing and scheduling the post.

  Done! Your post is scheduled.
  Post ID: abc-123

💻

Parallel Tasks

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.

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 Hashnode

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 Hashnode 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
✓Publication ID and tags resolved automatically from your settings
✓Cross-post to Hashnode + other platforms in a single session
✓Powered by Claude — Anthropic's most capable models

Also Works with Claude Cowork

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Claude Cowork, Anthropic's desktop agent — no terminal needed.

Claude Cowork

by Anthropic

Claude Cowork reads the Postiz skill so it knows what it can do, then autonomously discovers your Hashnode integration, uploads your cover image, resolves publication and tag IDs, and publishes the post.

Claude Cowork

> Publish my Node.js streams guide to
  Hashnode with a cover image and tags

Claude Cowork: Done! Scheduled on Hashnode for
  tomorrow at 9:00 AM.

Hashnode + Other Platforms

Publish the same article to Hashnode and other platforms in a single request. Each platform gets its own settings.

Example

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

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