About

Barcode and GTIN validation for AI agents.

README

Barcode / GTIN validation MCP (EAN-13, UPC-A, EAN-8, GTIN-14).

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

Tool	Description
`validate_gtin`	Validate a barcode number — EAN-13, UPC-A (12), EAN-8, or GTIN-14 (keyless, offline). Checks the mod-10 check digit, reports the format, normalizes to GTIN-14, and returns the GS1 prefix + issuing country/region. Spaces/dashes ignored. Validates the number, not the product.
`gtin_check_digit`	Compute the mod-10 check digit for GTIN/EAN/UPC data digits (all digits EXCEPT the check digit). Use to generate or repair a barcode.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "gtin": {
      "url": "https://gateway.pipeworx.io/gtin/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Gtin data" })

The gateway picks the right tool and fills the arguments automatically.
