Server tool list (17)
Raw names from tools/list. Only developers need these.
| 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. |
