README

barcode-scanner-mcp

MCP server for scanning and generating barcodes and QR codes.

Use Cases

Decode a barcode from a photo: "What does this barcode say?" → reads the image, detects the barcode format, and returns the decoded text.

Generate a QR code: "Create a QR code for https://example.com" → generates a PNG QR code image with configurable error correction.

Create shipping labels: "Generate a Code 128 barcode for tracking number 1Z999AA10123456784" → produces a barcode image in the specified format.

Verify printed barcodes: "Scan this product barcode and look up the item" → decodes the barcode and returns the text for further lookup.

Setup

claude mcp add barcode-scanner-mcp -- npx -y barcode-scanner-mcp

# Start the server
MCP_TRANSPORT=http PORT=3000 npx -y barcode-scanner-mcp
