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.

Gemini CLI extension

This repo is a Gemini CLI extension (gemini-extension.json at the root) and is indexed in the extensions gallery.

gemini extensions install https://github.com/gitroomhq/postiz-agent

It installs the postiz skill and the hosted Postiz MCP server (https://mcp.postiz.com/mcp-oauth-dynamic). Gemini CLI opens a browser to sign in to Postiz on first use; run /mcp auth postiz to re-authenticate. The skill drives the postiz CLI for media uploads, so install it with npm install -g postiz for image or video posts.

Qwen Code

Qwen Code installs Claude Code marketplaces directly, so no separate manifest is needed:

qwen extensions install gitroomhq/postiz-agent:postiz

DeepSeek Harness plugin

This repo ships a DeepSeek Harness (dsh) bundle at plugins/dsh-postiz. It connects the agent to the hosted Postiz MCP server and registers a postiz workflow skill.

dsh plugin --profile web add "github:gitroomhq/postiz-agent#path:/plugins/dsh-postiz"
export POSTIZ_API_KEY=your-api-key   # Postiz → Settings → Developers → Public API
dsh web
