About the Cartquay scanner

Someone asked Cartquay to check whether your site works for AI shopping agents. The scanner makes a few requests, the same ones an agent would make, and stops.

How to recognize it

Requests carry this User-Agent:

CartquayScanner/0.1 (+https://cartquay.com/scanner)

What it requests

  • /robots.txt and /llms.txt
  • /.well-known/ucp, the UCP business profile
  • One MCP initialize call: the endpoint your UCP profile declares, or /mcp and mcp. on your domain
  • Paid URLs only when the person scanning names them on your own domain

Its limits

20

requests at most per scan

256 KiB

read at most per response

0

forms sent, logins, or orders placed

Scans are also limited per visitor.

Stopping it

Block the CartquayScanner user agent at your firewall or CDN, or ask us to stop scanning your domain.

Ask to exclude your domain
