dsh-postiz

npm: dsh-postiz · source: gitroomhq/postiz-agent

DeepSeek Harness (dsh) plugin for Postiz, the open-source social media scheduler. It connects the agent to the Postiz MCP server so it can list your connected channels, fetch each platform's posting rules, and schedule, draft, or publish posts across 28+ platforms (X, LinkedIn, Instagram, Facebook, Threads, TikTok, YouTube, Reddit, Pinterest, Bluesky, Mastodon, Discord, Slack, Telegram, and more).

Install

From the repository:

dsh plugin --profile web add "github:gitroomhq/postiz-agent#path:/plugins/dsh-postiz"

Or from npm:

dsh plugin --profile web add dsh-postiz

Then give it a Postiz API key. Copy it from Postiz → Settings → Developers → Public API and export it before starting dsh, or put it in $DSH_HOME/.env:

export POSTIZ_API_KEY=your-api-key
dsh web

Restart the profile after installing. Ask the agent "List my connected social media accounts" to verify the connection.

What you get

The bundle mounts two rows:

Row	Package	Role
postiz	dsh-postiz (this package)	Reads the API key, exposes ctx.postiz (url, headers), and registers the postiz skill that teaches the agent the posting workflow and the HTML content rules.
postiz-mcp	@deepseek-ai/dsh-mcp-client (shipped with dsh)
