Chromium-Style QR Code

中文文档

An MCP (Model Context Protocol) server for generating Chromium-style QR codes with circular modules, rounded locators, and an optional center image (Dino logo or custom).

Features

• Chromium-style rendering — circular dot modules, rounded locator corners, matching the QR codes generated by Google Chrome
• Dino logo — the iconic Chrome Dino is drawn in the center by default
• Custom center image — supply a Base64-encoded image to replace the Dino
• Toggle center image — set showLogo: false to generate a plain QR code
• MCP-native — communicates over stdio, works with any MCP-compatible client

Installation

Note: The type: "stdio" field is not required — it's the default transport for MCP servers configured with command and args.

Using npx (recommended)

No installation required:

{
  "mcpServers": {
    "io.github.chromium-style-qrcode/mcp": {
      "command": "npx",
      "args": ["-y", "@chromium-style-qrcode/mcp"]
    }
  }
}

Using bunx

{
  "mcpServers": {
    "io.github.chromium-style-qrcode/mcp": {
      "command": "bunx",
      "args": ["@chromium-style-qrcode/mcp"]
    }
  }
}

Global install

npm install -g @chromium-style-qrcode/mcp

Then configure the MCP client:

{
  "mcpServers": {
    "io.github.chromium-style-qrcode/mcp": {
      "command": "chromium-style-qrcode-mcp"
    }
  }
}

Tool

generate_qr_code

Generate a Chromium-style QR code and return it as a PNG image.

text	string	Yes	—	The text or URL to encode
