An OpenClaw Skill for QR code generation and decoding, powered by MCP.

qrcode-skill is a standard OpenClaw skill that provides QR code generation and decoding capabilities through a remote MCP (Model Context Protocol) service. It can be used as a slash command (/qrcode-skill) in any compatible AI coding agent.

• Generate QR Code — Convert any text or URL (up to 1000 characters) into a QR code PNG image with configurable size (128–1024px)
• Decode QR Code — Extract text content from a QR code image (base64-encoded PNG)

Copy the skill folder into your project or personal skills directory:

# Project-level
.github/skills/qrcode-skill/

# Or personal-level
~/.copilot/skills/qrcode-skill/
~/.agents/skills/qrcode-skill/
~/.claude/skills/qrcode-skill/

Add the following MCP server configuration to your editor settings:

VS Code (settings.json):

{
  "mcp": {
    "servers": {
      "qrcode": {
        "type": "http",
        "url": "https://qrcode.api4claw.com/mcp"
      }
    }
  }
}

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "qrcode": {
      "type": "http",
      "url": "https://qrcode.api4claw.com/mcp"
    }
  }
}

Type /qrcode-skill in the chat or simply describe what you need:

Generate a QR code for https://github.com

Decode the QR code in ./images/ticket.png
