postiz — Claude Code plugin: what it does, how to install
Lets Claude Code schedule social media updates, query connected channels, and upload assets via the Postiz command-line tool.
/plugin install postiz@claude-plugins-official
/plugin marketplace add anthropics/claude-plugins-community
/plugin install postiz@claude-community
/plugin marketplace add anthropics/claude-plugins-officialWhat postiz does
The plugin connects your agent to the Postiz service using its CLI wrapper. It enables Claude Code to inspect connected platforms, pull channel schemas, fetch contextual metadata such as subreddit flairs or video playlists, and prepare scheduled entries across 28+ supported networks.
Unlike setups in some other environments, the Claude Code version functions purely as a skill CLI integration rather than registering an MCP server. Because of this, you must install npm install -g postiz globally on your machine. Authentication requires running postiz auth:login or defining POSTIZ_API_KEY. Without active credentials in your environment, dispatching posts will fail.
What it helps with
- schedule social posts across connected accounts
- retrieve channel settings and character constraints
- fetch external channel metadata like playlists and flairs
- handle media file attachments through the local CLI
Example prompts for the agent
- List all active social accounts connected to Postiz
- Check the settings schema for integration reddit-123
- Draft and schedule an announcement post for tomorrow morning
