KunatoCrawler
KunatoCrawler is a bot that browses the web on its own to finish multi-step tasks, and its operator has not been publicly identified. The token has been seen in server logs, but no operator has published documentation for it. No IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine and a robots.txt rule alone will not stop a forgery.
No operator has published documentation for this token. Everything below is what can be established from the string itself and from how the traffic behaves. We would rather say that than fill the gap with a guess.

Allow or block KunatoCrawler
Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.
User-agent: KunatoCrawler
Disallow: /Blocks every path for this crawler only.
User-agent: KunatoCrawler
Allow: /Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.
User-agent: KunatoCrawler
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /searchEdit the Disallow paths to match your own account, checkout and search URLs.
What blocking actually costs you
Blocking KunatoCrawler stops automated sessions that fill forms, click through flows and read pages the way a logged-in user would. Rate limits and challenges usually work better here than a robots.txt line.
Block every crawler in the directory at onceIs that really KunatoCrawler?
A user-agent header is a string the client chooses. Scrapers copy KunatoCrawler precisely because site owners allow it. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof.
Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
