What it looks like in server logs
A representative user-agent string. Version numbers change; the NovaAct token does not. Paste your own log line into the user-agent checker to confirm a match.
Mozilla/5.0 (compatible; NovaAct/1.0)How to block NovaAct
Add this to the robots.txt at the root of your domain. Robots.txt is advisory: it works only on crawlers that choose to read it. This one is undocumented. To enforce a block, match the user agent at your CDN or web server and return 403.
User-agent: NovaAct
Disallow: /
To block every agentic browser at once, or to block training while keeping AI search citations, use the robots.txt generator.
How to allow NovaAct while blocking others
A more specific User-agent group wins over a wildcard. Place this above any User-agent: * block that disallows paths, and NovaAct keeps full access.
User-agent: NovaAct
Allow: /
How to verify a genuine hit
The user-agent string is self-asserted: anyone can send it from a laptop, and scrapers routinely impersonate well-known crawlers to slip past filters aimed at unknown ones.
