## Trust

- hygiene: 80
- liveness: 100
- freshness: 85
- provenance: 35
- drivers: +reachable +uptime-100% ~updated-90d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 100/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 17 of 17 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 4,010 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 17, about 4,010 tokens to load them all
- tool set hash: 3a9ea3b4dd009671df2c88f6158f4e17
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.troyhunt/hibp.svg)](https://protogrid.dev/servers/io.github.troyhunt/hibp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (17)

- `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_get_breach`: Look up a single public HIBP breach by its canonical breach name, such as Adobe.
- `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_breached_domain`: Return breached aliases for a verified domain. This tool requires an authorized subscription via OAuth bearer token.
- `hibp_get_latest_breach`: Return the most recently added public breach currently loaded into HIBP.
- `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_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_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_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_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_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_list_breaches`: List public HIBP breaches, optionally filtered by domain, spam-list flag, and verification status.
- `hibp_list_data_classes`: List the data classes used across public HIBP breach models, such as email addresses or passwords.
- `hibp_list_subscribed_domains`: List the domains associated with the authenticated HIBP subscription.
- `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.
- `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.
