utilities.qr_barcode_engine

What it does

Creates QR codes and barcodes, and reads them from images. It is one of the Media and vision tools in the Ahura Utilities catalogue: a ready-made MCP tool that an agent calls with a typed input and gets a structured result back, with no library to install and no sandbox to start.

How agents use it

Agents use qr and barcode tool to issue authentication codes or scan inventory. Because it is a plain tool call, it slots into a single agent turn or a step in an Ahura Workflow, and large inputs and outputs are passed by reference using a store:// address from Ahura Store.
