Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

AttackerView's quick website security check: reports problems with a domain's security headers, HTTP to HTTPS redirect, DNS, email authentication and TLS. Use when the user asks things like 'is example.com secure?' or 'are my security headers, SSL, SPF or DMARC set up right?'. Passive check in seconds: one homepage request. No login, crawling or attacks, so it cannot find application vulnerabilities.
Domain or URL, e.g. example.com. Only the hostname is used.
