Tools as reported by the server

• hibp_list_breaches
  List public HIBP breaches, optionally filtered by domain, spam-list flag, and verification status.
• hibp_get_breach
  Look up a single public HIBP breach by its canonical breach name, such as Adobe.
• hibp_get_latest_breach
  Return the most recently added public breach currently loaded into HIBP.
• hibp_list_data_classes
  List the data classes used across public HIBP breach models, such as email addresses or passwords.
• hibp_get_pwned_passwords_range
  Query the public Pwned Passwords k-anonymity API with a 5-character SHA-1 or NTLM prefix and return matching suffixes with prevalence counts.
• hibp_get_breached_account
  Search HIBP for breaches affecting a single email address. Requires an OAuth bearer token linked to an active HIBP API subscription; use domain and verification filters to refine the result.
• hibp_get_breached_account_range
  Query the authenticated HIBP k-anonymity breached-account range endpoint with the first 6 characters of a SHA-1 email hash. Requires a subscription with k-anonymity access; compare each returned suffix with the remaining hash characters locally because a prefix alone cannot identify an account.
• hibp_get_paste_account
  Search for public pastes containing a single email address. Requires an OAuth bearer token linked to an active HIBP API subscription; run this separately from breached-account lookup.
• hibp_get_breached_domain
  Return breached aliases for a verified domain. This tool requires an authorized subscription via OAuth bearer token.
• hibp_list_subscribed_domains
  List the domains associated with the authenticated HIBP subscription.
• hibp_get_subscription_status
  Return the current plan, quotas, rate limits, expiry, and feature flags for the active HIBP API subscription linked to the authenticated OAuth connection. Use it to confirm access before feature-dependent lookups.
• hibp_get_stealer_logs_by_email
  Return website domains historically observed in stealer logs for an email address. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_get_stealer_logs_by_website_domain
  Return email addresses historically observed in stealer logs for a website domain. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_get_stealer_logs_by_email_domain
  Return email aliases and associated website domains historically observed in stealer logs for an email domain. Requires an OAuth-linked active subscription with the stealer-log feature; results do not establish current account access.
• hibp_generate_domain_verification_dns_token
  Generate the TXT record value required to verify domain control via DNS, creating or reusing the private HIBP domain-verification records needed for the request. Requires an authenticated subscription with domain-verification access.
• hibp_verify_domain_verification_dns_token
  Complete domain verification by checking the expected HIBP TXT record on the target domain. Requires an authenticated subscription with domain-verification access.
• hibp_send_domain_verification_email
  Send a domain verification email to an approved alias such as admin or security. Requires an authenticated subscription with domain-verification access.
