## Tools

17 declared. Observed from a live `tools/list` probe.
- `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

- `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; re
- `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; re
- `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
- `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
- `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 acce
- `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.

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"hibp\": {\n      \"type\": \"http\",\n      \"url\": \"https://haveibeenpwned.com/mcp\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
