Our reading of QRX, from the data
QRX is an MCP server from qrxcodes, listed in the official MCP Registry.
Its endpoint requires sign-in or an API key just to list tools, so we haven't measured its token cost; we never use real credentials.
It runs either locally over stdio or as a hosted endpoint and needs one secret (QRX_API_KEY); use a scoped, least-privilege key.
