CVE Risk Check

Official7 tools

by nguyenhieuec

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

Model Context Protocol (MCP) Server: app.openkrill/cve

This MCP server, app.openkrill/cve, provides CVE triage guidance. It focuses on determining how severe a vulnerability is, whether it is exploited, and how likely exploitation is, based on the server’s described triage responsibilities.

🛠️ Key Features

CVE severity assessment
Determining whether a CVE is exploited
Estimating likelihood of exploitation

🚀 Use Cases

Prioritizing vulnerability remediation
Reviewing known or reported CVE exploitation status
Triage workflows that require severity and exploitation-likelihood signals

⚡ Developer Benefits

Exposes CVE triage logic through an MCP server interface
Supports automated decision-making based on severity and exploitation indicators

⚠️ Limitations

Available metadata does not specify additional tools, supported inputs/outputs, or integration targets
No tool count, topics, or README excerpt were provided

Captured live from the server via tools/list.

check_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.

Parameters1

cve

string

required

A CVE id such as "CVE-2021-44228"

Raw schema

{
  "type": "object",
  "properties": {
    "cve": {
      "type": "string",
      "pattern": "^[Cc][Vv][Ee]-[0-9]{4}-[0-9]{4,19}$",
      "maxLength": 30,
      "description": "A CVE id such as \"CVE-2021-44228\""
    }
  },
  "required": [
    "cve"
  ],
  "additionalProperties": false
}

check_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.

Parameters1

cves

array

required

Up to 10 CVE ids

  "type": "object",
  "properties": {
    "cves": {
      "type": "array",

      "description": "Up to 10 CVE ids"
    }
  },
  "required": [
    "cves"
  ],
  "additionalProperties": false
}

list_recent_kev

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.

Parameters3

days	integer	optional	How many days back to look (default 30)
keyword	string	optional	Only entries whose name contains this word, such as "Chrome" or "Cisco"
limit	integer	optional	How many entries to return, newest first (default 20)

Raw schema

{
  "type": "object",
  "properties": {
    "days": {
      "type": "integer",
      "minimum": 1,
      "maximum": 90,
      "description": "How many days back to look (default 30)"
    },
    "keyword": {
      "type": "string",
      "minLength": 1,
      "maxLength": 60,
      "description": "Only entries whose name contains this word, such as \"Chrome\" or \"Cisco\""
    },
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 50,
      "description": "How many entries to return, newest first (default 20)"
    }
  },
  "additionalProperties": false
}

triage_dependencies

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 lockfile (package-lock.json, pnpm-lock.yaml, yarn.lock, poetry.lock, uv.lock, Cargo.lock, go.sum or go.mod), a package.json or a 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.

Parameters3

packages	array	optional	Installed packages: ecosystem (npm, pypi, go, crates.io, maven, rubygems, nuget, packagist), name and exact version. Up to 300.
manifest	string	optional	The text of one dependency file. Lockfiles give exact versions: package-lock.json, pnpm-lock.yaml, yarn.lock (npm), poetry.lock, uv.lock (PyPI), Cargo.lock (crates.io), go.sum or go.mod (Go). A package.json is read at the lowest version of each range, a requirements.txt only for == pins. Only names and versions are read; workspace, git, path and url entries are skipped.
limit	integer	optional	How many packages to put in fix_first (default 3)

search_oss_security

Use this when the user asks whether a security issue was announced for an open-source package, such as "any recent security advisories for ffmpeg?", or what the oss-security list says about a CVE. Pass package (a name such as openssl, ffmpeg or tomcat) or cve, not both. Returns the matching oss-security mailing list threads of the current and previous quarter, newest first: subject, link and the CVE ids in the subject. A thread matches by its subject only, so no match does not mean no advisory. The list is refreshed once a week.

Parameters3

package	string	optional	A package or project name as advisories write it, such as "openssl", "ffmpeg" or "tomcat"
cve	string	optional	A CVE id such as "CVE-2026-12345"
limit	integer	optional	How many threads to return, newest first (default 20)

submit_feedback

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Parameters4

kind	string	required	need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.
message	string	required	What you need or what broke, in plain words, at most 1000 characters. Links, email addresses and phone numbers are removed. Never include secrets or personal details.
tool	string	optional	Optional: the exact name of the tool on this server that the feedback is about, as tools/list shows it.
error	string	optional	Optional: for a failed call, the error text it returned, copied as you saw it. Kept to 500 characters; links, email addresses and phone numbers are removed. Never include secrets or personal details.
