Have I Been Pwned
io.github.troyhunt/hibp · 1.0.0
Breach intelligence API: email search, domain monitoring, passwords and stealer logs.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 35 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 17 tools.

The tools it lists (17, as of 8 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
hibp_list_breachesList public HIBP breaches, optionally filtered by domain, spam-list flag, and verification status.
hibp_get_breachLook up a single public HIBP breach by its canonical breach name, such as Adobe.
hibp_get_latest_breachReturn the most recently added public breach currently loaded into HIBP.
hibp_list_data_classesList the data classes used across public HIBP breach models, such as email addresses or passwords.
hibp_get_pwned_passwords_rangeQuery 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_accountSearch 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_rangeQuery 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_accountSearch 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.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
io.github.troyhunt/hibp, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
