CVE Risk Check
Triage a CVE: how severe it is, whether it is exploited, and how likely exploitation is.

🟢check_cve(cve)
Use this when the user asks how serious a CVE is, such as "how bad is CVE-2021-44228?". Pass the CVE id. Returns a priority (exploited, likely, routine or unknown), the description, CVSS score and severity, whether the CISA Known Exploited Vulnerabilities catalog lists it, the EPSS exploitation probability, a patch or advisory link when tagged, and the as_of dates. A lookup by CVE id: it does not know which software the user runs or whether they are affected.

}🟢check_cves(cves)
Rank several CVEs. Use this when the user has a list of CVE ids and wants to know which to deal with first, such as "which of these CVEs should I patch first?". Pass up to 10 CVE ids. Returns each one's priority, CVSS score, CISA exploited-list status and EPSS score, most urgent first, with a count per priority. An id NVD could not be asked about in this call is marked deferred; ask for it again later. It does not know which software the user runs.

}🟢list_recent_kev(days, keyword, limit)
Use this when the user asks what CISA recently added to its Known Exploited Vulnerabilities list, such as "what exploited CVEs were added this month?". Optionally pass how many days back (up to 90), a product word to filter by, and a limit. Returns each CVE with its CISA name, the date it was added, CISA's due date and its CVSS score, newest first. The catalog lists vulnerabilities with evidence of exploitation; it is not a list of every serious CVE.

}🟢triage_dependencies(packages, manifest, limit)
Use this when the user wants to know which vulnerable dependencies to fix first, such as "which dependencies in this package-lock.json should I upgrade first?" or "triage my requirements.txt". Pass the text of a package-lock.json, package.json or requirements.txt as manifest, or a packages list of ecosystem, name and exact version (npm, pypi, go, crates.io, maven, rubygems, nuget, packagist); only names and versions are read. Returns fix_first: by default the 3 packages to upgrade first, each with a priority (malicious, exploited, likely, routine or unknown), one line on why, the CVE ids and the version that fixes it, then a short list of the other vulnerable packages and a count per priority. It matches exact package versions to known advisories; it does not scan code or show that the vulnerable code is reached.

Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
