Nothing serious here today

Today is the operative word: we check AlertsBar every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 2

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

exposure
exposure_counts_for_domain
Credential-exposure counters for a domain. Counts only - no credential values or per-account detail. Sources: known breaches, infostealer infections, unattributed heap of ULP (Url,Login,Password) bundles, stolen cookies. All figures are INDEXATION dates, not incident dates: _month/_week mean 'newly indexed', never 'newly leaked' - the underlying leak may be years old. Windows nest (_total includes _month includes _week) - never sum them. Counters are rebuilt once daily, so figures are up to 24h old and never real-time. Repeated calls for the same input within a day return identical values - do not re-query to check for changes. Accepts a bare domain or a full URL; scheme, path, port, case and a leading www. are stripped and subdomains collapse to the registrable domain (multi-tenant hosting suffixes such as github.io are not collapsed). An IDN must already be in punycode (xn--) form. Invalid input (not a domain, an IP address) returns an error. If the domain is not in the index at all, every counter and both dates are null: that means NO DATA, not that the domain is clean - never report it as 'no exposure'. first_indexed_at and last_indexed_at give the date range of the domain's records; use last_indexed_at as the 'last updated' date for the domain. Free, no auth.
exposure_samples_for_domain
A small RANDOM sample of individual exposure records for a domain - metadata only, capped in number: up to 20 records per type (stealers_users, stealers_staff, heap_users, heap_staff, breaches). Cookies are not sampled - see cookies_* in exposure_counts_for_domain. The sample is neither the newest nor the largest nor the most severe records, and it can differ between calls; identical-looking records can repeat and because of different logins/passwords. Each record says WHICH url was affected, WHICH domain the captured login belonged to, from WHICH source type, roughly when the incident was, and when the record was indexed. It carries NO credentials: no password, no username, and the login's local part is redacted. Use exposure_counts_for_domain first for the scale of the problem and for freshness (last_indexed_at); use this only when the user asks to see concrete examples. Calling again returns another random subset, never the full set - do not call it repeatedly to collect more records.

AlertsBar — questions

Answers built from our own checks of this server.

What can AlertsBar do?
It exposes 2 tools, read directly from the server on our last check. Among them: exposure_counts_for_domain, exposure_samples_for_domain. 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 AlertsBar 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 57 ms. The bar chart above shows every period we have measured.
How do I connect AlertsBar?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does AlertsBar need an API key?
No. AlertsBar completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AlertsBar?
It answers our handshake in 57 ms on average, which is faster than 99% 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.
