Claude Code plugin

/plugin marketplace add gitroomhq/postiz-agent
/plugin install postiz@postiz-agent

Grok Build plugin

Postiz is listed in the xAI plugin marketplace — install it from the marketplace inside Grok Build. This repo also carries its own .grok-plugin/plugin.json manifest and .grok-plugin/marketplace.json catalog, so it can be added as a marketplace source directly.

The Grok plugin also bundles the hosted Postiz MCP server (https://mcp.postiz.com/mcp-oauth-dynamic) via the mcpServers field in .grok-plugin/plugin.json — you'll be asked to sign in to Postiz on first connection; no token or local install needed. The Claude Code and Cursor plugins are skill/CLI-only and do not register an MCP server.

Cursor plugin

This repo ships a Cursor plugin manifest at .cursor-plugin/plugin.json.

• From the marketplace / Customize panel: open Customize in the Cursor sidebar, find postiz, and select Install (project or user scope).
• Local install (development):

  git clone https://github.com/gitroomhq/postiz-agent.git
  ln -s "$(pwd)/postiz-agent" ~/.cursor/plugins/local/postiz

then restart Cursor or run Developer: Reload Window.

The plugin exposes the postiz skill, which drives the postiz CLI (the CLI handles media uploads, which is required for image/video posts). Make sure the CLI is installed (npm install -g postiz) and authenticated (postiz auth:login or export POSTIZ_API_KEY=...) before asking the agent to post.
