## Tools (as reported by the server, not verified)

- `check\_email\_security`: Checks whether a domain can be email-spoofed, using public DNS only. Verifies SPF \(including the RFC 7208 multiple-record permerror\), DMARC policy and reporting, MX, and DKIM at common selectors. Returns a graded report with concrete fixes. Accepts a bare domain, a URL, or an email address. Nothing
- `compare\_email\_security`: Runs the email-security check on 2–5 domains and returns a comparison table with per-domain grades. Useful for checking your domain against competitors.
