Enhanced QR Code

You deploy and use the Enhanced QR Code MCP Server to automatically generate QR codes, save them as PNG files with rich metadata, and manage batch processing with structured output. This server is designed for reliable file generation, organized results, and easy integration with MCP clients to fit production workflows.

How to use

You connect an MCP client to the Enhanced QR Code MCP Server to generate QR codes on demand. Use the server to create single QR codes or batch multiple codes in one request. Each generated QR code is saved as a PNG file with accompanying metadata, and files can be organized into an output directory of your choice. You can control encoding content, error correction, size, and border, and you can opt to generate and store metadata for each code.

Key capabilities you can rely on include:

• Creating a single QR code and saving it as PNG with optional metadata
• Generating multiple QR codes in a single batch call
• Listing and organizing generated QR codes with their metadata
• Customizing file names and output directories to fit your project structure

How to install

Follow these concrete steps to set up the server locally. Ensure you have Python 3.8 or higher and an MCP client available for testing.

# Quick setup
git clone https://github.com/myownipgit/enhanced-qrcode-mcp.git
cd enhanced-qrcode-mcp
chmod +x setup.sh
./setup.sh

Configuration and usage notes

Configure your MCP client to use the Enhanced QR Code MCP Server by pointing it to the local script that runs the server. The server is designed to be invoked via a standard input/output (stdio) MCP channel, so you provide a command and arguments to launch the Python script that hosts the server.

Example client configuration snippet:

{
  "mcpServers": {
    "enhanced_qrcode": {
      "command": "python3",
      "args": ["/path/to/enhanced-qrcode-mcp/src/enhanced_qrcode_server.py"],
      "env": {},
      "description": "Enhanced QR code generator with automatic PNG file saving"
    }
  }
}

File organization and outputs

Generated outputs are saved under an output directory you specify. Each QR code yields a PNG file and a metadata JSON file. When you run batch operations, a batch manifest file is produced to help track produced assets.

Troubleshooting and tips

If you encounter permission issues during setup, ensure the script has execute permissions and your user account has rights to the project directory.

If a QR code fails to save, verify the output directory exists, you have write permissions, and there is sufficient disk space.

Tools and capabilities reference

The server exposes a set of tools you can call via its MCP interface to generate and manage QR codes.

Available tools

generate_and_save_qrcode

Generates a single QR code from provided content and saves it as a PNG file along with a JSON metadata file.

batch_generate_qrcodes

Generates multiple QR codes from an array of inputs in a single operation and saves each as PNG files with individual metadata and a batch manifest.

list_generated_qrcodes

Lists all generated QR code files within a target directory and includes associated metadata.
