MCP support

Exposes image decoding and barcode or QR code generation tools to MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "domdomegg-barcode-scanner": {
      "command": "npx",
      "args": [

        "barcode-scanner-mcp"
      ],
      "env": {
        "MCP_TRANSPORT": "<MCP_TRANSPORT>"
      }
    }
  }
}

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project 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

Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
