How to give OpenClaw your accounts

  1. 1

    Install the Groniz skill

    OpenClaw discovers skills by their SKILL.md. Install Groniz and it learns every command.

    npx skills add groniz/groniz-cli
  2. 2

    Or add the MCP server

    Add Groniz with the key in the URL — the simplest form, and it avoids OpenClaw’s header edge cases.

    openclaw mcp add groniz \
  --url https://mcp.groniz.com/mcp/YOUR_API_KEY \
  --transport streamable-http
  3. 3

    Message it

    From WhatsApp or Telegram, tell OpenClaw what to post.

    You: Post my new blog to X and LinkedIn, schedule for tomorrow 9am
Before you rely on it
  • Put the API key in the MCP URL rather than a header — OpenClaw ignores static Authorization headers when OAuth is enabled, and header forwarding has been unreliable.
Once it’s connected

What OpenClaw can do for you

The Groniz surface is the same everywhere; what changes is how OpenClaw reaches for it.

Try Message it from WhatsApp: post my blog to X and LinkedIn, 9am tomorrow.

OpenClaw runs on your own machine and reaches you from WhatsApp, Telegram or Slack — so the distinctive move is scheduling a post by text message, no app open.

Every command below runs against your real Groniz account — the same posting, scheduling and analytics the Console gives you.

OpenClaw questions

OpenClaw + Groniz, answered

How do I install the Groniz skill?+
With OpenClaw’s skill installer — it fetches the SKILL.md and OpenClaw learns the groniz commands. From then on you can message it from any connected chat app to schedule posts.
Should I use the skill or MCP?+
The skill is the smoothest fit — OpenClaw is built around skills, and the Groniz CLI it wraps outputs JSON. MCP also works; if you use it, put the key in the URL rather than a header.
