Autonomous agents
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.

Paste one at the root of your domain. Rules are per token.

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.

Not documented. No operator statement says whether KunatoCrawler reads robots.txt, so add the rule but verify in your logs that the requests actually stop.
You cannot, at least not from the request itself. 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. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.
Add the KunatoCrawler token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.
