このMCPでできること

Performs live SPF, DKIM, DMARC, subdomain takeover, and WHOIS checks and provides security base-rate data.

check_email_auth
Check email authentication (live)
Live SPF, DKIM and DMARC audit of up to 50 domains the user owns or asks about. Returns a per-domain breakdown plus a portfolio grade. Compare against the base rates: most of the web fails these controls. Rate-limited per client.

Array preferred; a JSON-encoded array or comma/space-separated string also works.'}}, 'additionalProperties': False}
check_subdomain_takeover
Check subdomain takeover exposure (live)
Live scan of one domain: enumerate its subdomains (CT logs + DNS), then test each for dangling references on 13 cloud providers. Slow on large domains (up to a few minutes). Rate-limited per client.

check_whois
Check domain registrations (live)
Live WHOIS lookup for up to 100 domains: expiry date, registrar, nameservers. Use to catch registrations about to lapse. Rate-limited per client.

get_base_rate
Get one base rate in full
Full detail for one Quiet Failures base rate segment: the figure with confidence interval, how it is measured, why it matters, the limits of the measurement, the recent time series, and the canonical source URL to cite. Segment defaults to "global"; country slugs (gb, fr, us…) and company cuts (gb-companies, gb-small…) are also published.

list_base_rates
List security base rates
Catalog of all published Quiet Failures base rates: metric id, the global question, the current global figure, sample size, severity, and every published segment slug (valid `segment` values for get_base_rate). Use get_base_rate for full detail on one.
