Postiz is the agentic social media scheduling platform that OpenClaw drives through the Postiz skill. Please make sure there is always a human in the loop. Last updated: September 2026. Home/OpenClaw
How do you install the Postiz skill in OpenClaw?
Install the skill from ClawHub or with the skills CLI, sign in to Postiz once, and confirm OpenClaw lists the skill as eligible. Both commands below add the same Postiz skill to OpenClaw.
Run this where OpenClaw runs
One command adds the Postiz skill from ClawHub. Sign in once and OpenClaw can post to every channel through Postiz.
# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz
# Sign in with the OAuth2 device flow
postiz auth:login
# Verify OpenClaw sees the skill
openclaw skills list --eligible
openclaw skills checkPrefer the skills CLI? Run npx skills add gitroomhq/postiz-agent instead. Headless servers can export POSTIZ_API_KEY rather than signing in. Full reference in the Postiz CLI docs.
Message OpenClaw from any chat app
OpenClaw reads the Postiz SKILL.md, runs the CLI and confirms the schedule. Posts publish at the set time even after you close the chat.

How does OpenClaw authenticate to Postiz?
OpenClaw authenticates to Postiz, never to the social networks themselves. Your X, LinkedIn, or Instagram accounts stay connected to Postiz with OAuth, and you can revoke OpenClaw's access from Postiz at any time.
| Method | How it works | Best for |
|---|---|---|
postiz auth:login | OAuth2 device flow: a one-time code opens the browser, credentials are saved to ~/.postiz/credentials.json | Recommended for a personal OpenClaw gateway |
POSTIZ_API_KEY | API key from Postiz settings, exported in the environment where the OpenClaw gateway runs | Headless servers and automations |
One skill posts to every channel you run
Connect your accounts in Postiz once. From then on OpenClaw can post to any of them from WhatsApp, Telegram, Slack or Discord, and Postiz publishes at the time you set.
Is OpenClaw an MCP server?
No. OpenClaw is an agent gateway, and Postiz connects to it as a skill, not through MCP. OpenClaw reads the Postiz SKILL.md and runs the Postiz CLI. OpenClaw can also connect to MCP servers as a client, but for OpenClaw the skill is the recommended path. If you use an MCP-native agent such as Claude or ChatGPT, use the Postiz MCP server instead. OpenClaw is also not the same project as NanoClaw.
| Integration surface | How Postiz is called | Install | Auth | Best for |
|---|---|---|---|---|
| OpenClaw skill (this page) | OpenClaw reads SKILL.md and runs the Postiz CLI | openclaw skills install @nevo-david/postiz | postiz auth:login (OAuth2) or POSTIZ_API_KEY | OpenClaw users posting from WhatsApp, Telegram, Slack, Discord |
| Postiz MCP server | MCP client calls Postiz tools over Streamable HTTP | Add https://mcp.postiz.com/mcp-oauth-dynamic to an MCP client | OAuth in the MCP client, no API key | Claude, ChatGPT, Cursor and other MCP-native agents |
| NanoClaw | Separate project (qwibitai/nanoclaw) that runs the Postiz CLI and MCP tools | See the NanoClaw guide | Postiz CLI login or MCP OAuth | People already running NanoClaw instead of OpenClaw |

What is OpenClaw?
OpenClaw is an open-source, self-hosted gateway that connects your chat apps to AI agents. It runs on your own machine or server, listens on WhatsApp, Telegram, Slack, Discord, Signal, iMessage, and more, and takes real actions through skills, including managing your social media with Postiz.
Message From Anywhere
Talk to OpenClaw from WhatsApp, Telegram, Slack, Discord, Signal, iMessage, Google Chat, IRC, Teams, Matrix, and more. No new app to learn.
Skill-Based Architecture
OpenClaw extends its abilities through Skills — lightweight Markdown plugins. Postiz is available as a skill on ClawHub, the open-source registry with 13,000+ skills.
Proactive Automation
Create OpenClaw automations on a cron expression. OpenClaw can post to your socials on a schedule, checking for new content and publishing without you lifting a finger.
How Postiz Becomes an OpenClaw Skill
When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose posts with the right settings for each platform.
- Install from ClawHub with one command: openclaw skills install @nevo-david/postiz
- OpenClaw reads the SKILL.md and learns all Postiz commands
- Run openclaw skills check to confirm the postiz binary and credentials are in place
- Skills are loaded on-demand, keeping the agent context clean
- Works with any LLM backend: Claude, GPT, Gemini, Llama, and more
# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz
# Or with the skills CLI
npx skills add gitroomhq/postiz-agent
# Sign in with OAuth2 (or set POSTIZ_API_KEY)
postiz auth:login
# Verify OpenClaw sees it

openclaw skills checkHow do you post to social media from WhatsApp or Telegram with OpenClaw?
Message OpenClaw from WhatsApp, Telegram, or Slack — it reads the Postiz skill, discovers your integrations, and handles the entire posting workflow autonomously.
From Any Chat App
WhatsApp, Telegram, Slack, Discord...
Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your accounts via Postiz, uploads media, and schedules posts — all while you go about your day.

openclaw automations for recurring content
OpenClaw automations run a prompt on a cron expression in an isolated session and can announce the result to a chat channel. Set up a weekday job that checks for new content and schedules it through Postiz, no manual trigger needed.
openclaw automations create "0 9 * * 1-5" \
"Check ~/content/pending for new posts. Upload any media, then schedule to X, LinkedIn, and Instagram for today at noon. Move posted files to ~/content/done." \
--name "Daily social posts" \
--session isolated \
--announce --channel telegram \
--to "<your chat id>"
