Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

breach
breach_history
Search the FULL historical breach archive — every incident this server knows about, back to 2007: HaveIBeenPwned's verified breach directory, the 2020-2025 ransomwatch leak-site archive (~16k victims), the RansomLook live tracker and SEC 8-K Item 1.05 filings. Filter by keyword, year range, sector, exposed data type or minimum scale; order by date or size. Returns disclosure metadata only, never breach contents. Use this for questions like 'what were the biggest breaches of 2013' or 'which airlines have ever been hit by ransomware'.
breach_news
Read recent breach and ransomware DISCLOSURES from public threat-intel feeds (HaveIBeenPwned, the RansomLook live leak-site tracker and SEC 8-K Item 1.05 filings), newest first. Every row is metadata only — entity, date, scale, exposed data TYPES, threat level and source — never the leaked data, and a redaction pass strips anything credential-shaped before it is returned. Use sector to narrow to an industry keyword; for one specific organization use check_exposure; for all-time history use breach_history.
breach_stats
Aggregate the full breach archive into analyst-grade statistics: incidents and accounts exposed per year, per source, per exposed data type, per threat level, or per ransomware actor — plus the five largest incidents ever recorded. Use it to answer 'how has breach volume trended since 2015', 'which ransomware groups have the most victims' or 'how often are passwords part of a breach'. Aggregate counts only; no leaked records.
breach_timeline
Build the incident-by-incident CHRONOLOGY of one organization across every source and all history, with judgment on top: first and latest incident, incidents per year, whether the organization is a repeat victim, worst threat level and total accounts ever exposed. Those summary fields cover EVERY incident on record. The timeline list carries a window of them, oldest first within the window, defaulting to the most recent limit incidents and paging backwards with offset, so an organization with a long history shows its current state first rather than only its ancient one. Repeat victimhood is a forward-looking risk signal: organizations named more than once have demonstrably not closed the gap. Metadata only; never the leaked data. For a yes/no presence check use check_exposure.
assess
assess_threat
Classify a piece of security text you supply — an advisory, alert or forum post — into a threat level, matched categories, financial-target flags, a confidence score and a recommended action. Pure local analysis: it collects nothing, stores nothing and reaches no network; the text never leaves the server. Use it to triage findings surfaced by breach_news or from your own monitoring.
exposure
check_exposure
Answer whether a domain, company or brand appears in public breach or ransomware DISCLOSURES across ALL history (2007 → today): yes/no with mention count, worst threat level, total accounts exposed across matches, the exposed data TYPES, and the matching disclosure metadata — never the exposed records themselves. This is a triage signal built from disclosure feeds, not proof of compromise; confirm through authorized channels before acting. For the incident-by-incident chronology of one entity, use breach_timeline; for a recent-news sweep, use breach_news. mentions, the aggregates and the data types always cover every match; matches carries one page of them, sized by limit and walked with offset.
feed
feed_sources
List the public disclosure feeds this server aggregates, how many disclosures are cached per source, each source's newest item and an honest staleness flag, plus cache ages. Takes no arguments. Also states the scope plainly: public feeds only — no .onion access, no arbitrary fetching or crawling, no credential or PII output. Check this first if another tool's answer looks thin: a stale live feed is a finding, not background noise.

data-breach-detector — questions

Answers built from our own checks of this server.

What can data-breach-detector do?
It exposes 7 tools, read directly from the server on our last check. Among them: assess_threat, breach_history, breach_news, breach_stats, breach_timeline, check_exposure and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is data-breach-detector working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 107 ms. The bar chart above shows every period we have measured.
How do I connect data-breach-detector?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does data-breach-detector need an API key?
No. data-breach-detector completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is data-breach-detector?
It answers our handshake in 107 ms on average, which is faster than 82% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use data-breach-detector?
The pypi package data-breach-detector was installed 2 170 times in the last week. Week over week that is +2423%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is data-breach-detector open source?
Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
