Overview

What is Qr_check_server?

Qr_check_server is a Python tool that improves WeChat QR code recognition accuracy in large images containing small QR codes. It uses a two-stage detection pipeline: first a YOLOv8 model to locate small code regions, then the open-source WeChat QR code decoder (wechat_qrcode) to extract the content. It is designed for users who need reliable QR scanning in challenging image scenarios.

How to use Qr_check_server?

Install dependencies with pip install -r requirements.txt (MCP packages are optional if only the API is needed). Run python test.py for a quick trial, or start the HTTP API with python app.py and access it at http://127.0.0.1:8080/check?url=. For MCP support, run python mcp_qr_check_server.py to start an SSE server on http://0.0.0.0:8000.

Key features of Qr_check_server

  • Two-stage detection (YOLOv8 + WeChat QR decoder)
  • Improved recognition of small QR codes in large images
  • HTTP API endpoint (/check?url=) for integration
  • MCP SSE server on port 8000
  • Includes a standalone test script (test.py)

Use cases of Qr_check_server

  • Scanning small QR codes embedded in large posters or screens
