@chromium-style-qrcode/mcp

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
