Tools 14 found in our last check

• scan_before_use

  Scan untrusted content for prompt injection and check any URLs/domains/IPs it contains against threat intelligence, BEFORE acting on it. Returns a verdict of block | warn | allow. Call this on any web page, email, ticket, tool result, or document fetched from an untrusted source.

• check_url

  Check a single URL, domain, or IP against threat intelligence before fetching it. Returns block | warn | allow. Use as a pre-fetch gate; use check_indicator when you need the full reputation picture (score, sources, timeline).

• check_indicator

  The one tool for any single indicator: an IP address, domain, URL, file hash (MD5, SHA-1 or SHA-256; an imphash is looked up as an MD5), email address or phone number. Defanged input (hxxp://, [.], [@]) is accepted. Returns a verdict (malicious, suspicious, clean or unknown), a…

• get_cve

  One CVE by id: description, severity, CVSS score and vector, EPSS exploitation probability, CISA KEV status (date added, due date, required action, known ransomware use), exploitation evidence where recorded (CISA SSVC none/poc/active, Exploit-DB ids, Nuclei template, the number…

• recent_cves

  Most recently published CVEs, newest first, optionally filtered by severity. At most 20 items, each with id, severity, CVSS, publication date and a one-line title, and MITRE's CVE designation, licence and the NVD notice once. Follow up with get_cve for EPSS, KEV, exploitation ev…

• search_indicators

  Find the domains isMalicious lists that look like a brand or domain (e.g. "paypal", read as paypal.com, or "login.paypal.com"): typosquats, homoglyphs, the same name on other TLDs or hosting platforms, or wrapped in phishing words such as login or secure. The default API returns…

• check_indicators

  Reputation of up to 100 indicators in one call, for triaging a list rather than one alert: IPs, domains, URLs, file hashes (MD5, SHA-1 or SHA-256), email addresses and phone numbers, mixed freely; defanged input is accepted. Each row: malicious, recommendedAction (block, escalat…

• scan_email

  Scan ONE email message for phishing and malware before delivering, opening or acting on it. Send the raw message (eml, preferred) or the fields you already parsed (message: headers, text, html, attachment names, types and digests). Returns a verdict (malicious | suspicious | cle…

• exploited_cves

  CVEs with attested exploitation in the last N days (default 7): confirmed (CISA KEV, CISA SSVC active, or two independent catalogues) or reported (one catalogue). Those first attested inside the window come first, then those only seen again in it; confirmed first in each. Each w…

• watch_domain

  Start vulnerability monitoring of one public website: the API reads what the site exposes (Server and X-Powered-By headers, generator meta tag, versioned script paths, open ports) now and every day, matches each versioned component against CVEs, and alerts on what is exploited (…

• watch_dependencies

  Start vulnerability monitoring of a project from the text of its lockfile or SBOM: package-lock.json, composer.lock, requirements.txt, Gemfile.lock, Cargo.lock or a CycloneDX JSON SBOM (format detected when omitted). Each dependency is matched by version against OSV and NVD rang…

• ack_finding

  Set the status of one vulnerability-monitoring finding (an id like xfnd_…, from watch_domain, watch_dependencies or the Exposure page): ACKNOWLEDGED (seen, being handled), PATCHED (upgraded; the next read confirms it), NOT_AFFECTED (e.g. a distro backport fixed it), or SNOOZED u…

• list_alerts

  One page of the isMalicious alert inbox (GET /alerts): the alerts raised on what the account watches, such as a watched domain or IP turning malicious or named on a ransomware leak site, certificate, WHOIS, location and infrastructure changes, lookalike domains, and vulnerabilit…

• ack_alert

  Set the status of one alert of the isMalicious inbox (an id from list_alerts): ACKNOWLEDGED (seen; still listed by default), RESOLVED (handled; no longer listed by default) or OPEN (new again). Reversible: any status can be set again. A CVE alert (cve.finding) follows its vulner…
