What this skill does
Human-in-the-loop CAPTCHA solving with two modes: screenshot (default, zero infrastructure) and token relay (requires network access).
Captcha Relay is part of the Other Skills category — OpenClaw skills that extend your agent with new capabilities. You can install it on its own or alongside other other skills skills from the OpenClaw catalog.
How to install Captcha Relay
The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:
- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
captcha-relayand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Captcha Relay with a single command:
openclaw skills add captcha-relay
This pulls captcha-relay from ClawHub and installs it into ~/.openclaw/skills/captcha-relay/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Captcha Relay
Once installed, Captcha Relay activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Turning images into video
Captcha Relay works with images. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — turns stills into motion — pans and transitions, synced captions, and a vertical export for short-form feeds.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
