Frequently Asked Questions
Should I Block toCrawl?

For comparison, 1% of the top websites we track already have robots.txt rules for toCrawl.
Does toCrawl Follow Robots.txt Rules?
Yes. toCrawl is expected to follow robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms toCrawl actually follows it.
Does toCrawl Access Private Content?
Unknown. toCrawl has no documented scope, so watch what it actually requests. Repeated hits on login or admin paths are the signal to block it.
Why Is toCrawl Visiting My Website?
Nobody knows yet. toCrawl is undocumented, so until its operator explains it, its behavior on your site is the only evidence of its intent.
How Can I Tell if toCrawl Is Visiting My Website?
Agent Analytics tracks toCrawl visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "toCrawl". Log the paths it requests and how often, since nothing about it is documented. Keep in mind that toCrawl doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
