Cve Intelligence MCP Server

Known Chained Vulnerabilities™: pairs of CVEs that a cited source reports were used together in one exploit chain (VulnCheck KEV entry text, Metasploit modules, SigmaHQ rules, press, research or academic sentences, community text judged by a local model). Each row carries both CVEs with their CISA KEV status, the claim kind (observed: the source reports attacks; potential: the source reports they can be chained), the quoted evidence with its source, URL and date, and community discussion counts, which show discussion and are not chain claims. The per-CVE record carries chains.known and chains.candidates (KCV Watch: possible chains for teams to research, same-product pairs whose extracted exploit capabilities connect, derived and never confirmed, each with its tier, basis, shared product, bridge, grade, a caption and the entry step); search_cves accepts chained=1 and chainability=1. Filters: source (vulncheck_kev, metasploit, sigma, press, research, community), since (YYYY-MM-DD, first seen), claim (observed|potential), limit (1..500).

Full intelligence record for one CVE: per-scorer CVSS, EPSS, CISA KEV/ransomware/SSVC, four remote-detection modalities (the checks that work over the network) plus a host-check tier (self-contained Nuclei templates and Metasploit local modules that run on the system itself) and the Sigma log-detection layer, both kept out of scannable coverage, per-product fixed versions (fixed = first patched build; affected_through = the last vulnerable build, so upgrade past it), news/community coverage, intelligence summary. No key required over MCP; an API key on the HTTP request (Authorization: Bearer cvs_live_…) is honored for attribution. Absence semantics: a null field means this dataset holds no such record. The source may still hold one.

Search the catalog. Free text (q) and/or structured filters: vendor (slug), cwe (CWE-nnn), technique (ATT&CK id, such as T1190), year ("2024,2025"), sev ("critical,high"), kev (0|1), kev_from / kev_to (ISO days, half-open CISA listing window; imply kev=1), kev_vendor (the CISA vendorProject string verbatim, such as "Microsoft"), ransomware (0|1), detect (0|1, a detection signal we track), fix (0|1; fix=0 means the fix status was computed and this dataset holds no actionable vendor fix), automatable (0|1, CISA SSVC Automatable; 1=yes, 0=CISA assessed no, unassessed CVEs match neither), sighted (7|30: a named sensor network recorded the CVE in the last 7 or 30 days, a field sighting; presence per day, apart from the exploitation claims), malware (0|1: a published source ties a named malware family, tool, campaign or ransomware group to the CVE), watch (0|1: on KEV Watch at tier 1 or 2, reported exploited by trackers other than CISA and outside CISA KEV), epss_gte (0..1), eco (OSS ecosystem, such as npm or PyPI), pkg (pkg_key, such as npm/lodash; for ranges use query_package), page, limit (1..50). Filter-only queries return the /browse slice ordered KEV-first then EPSS.

CVEs whose EPSS exploitation probability rose the most recently. window is "7d" (default) or "30d". Each rise is measured between same-EPSS-model-version scores, so a model release (which shifts the whole distribution) never appears as a mover. A rise raises the priority of a CVE; observed exploitation is recorded through CISA KEV. Returns cve_id, current score, the delta, KEV status and url, largest rise first.

CVEs affecting one open-source package, by purl (pkg:npm/lodash) or ecosystem + name (Maven names are group:artifact). Returns the CVE list KEV-first with each OSV version range VERBATIM: `events` plus one render-safe projection: `fixed` (the upgrade targets) or `affected_through` (the last VULNERABLE version, so upgrade past it). This tool does not evaluate version membership; compare versions on your side with your ecosystem’s own semantics. Covers CVE-linked, GitHub-reviewed OSS advisories via OSV.dev; absence is not evidence of safety.

The Defender Scoreboard report (CC BY 4.0): exploited vs detectable vs patchable, every figure with its method, caveat and denominator, plus the corpus block and any method-change notes. Cite as "CVE Security Defender Scoreboard, cve-security.com/scoreboard".

Field sightings: CVEs a named sensor network recorded in the last 7 or 30 days, most sighting days first. A field sighting is a day on which Shadowserver honeypots (cited by VulnCheck KEV and published as daily lists by CIRCL Vulnerability-Lookup) or VulnCheck canary sensors recorded traffic aimed at the CVE. Each row carries first and last sighting day, days sighted in the last 7 and 30, the sensors, and per-sensor detail including a 30-day presence strip. Presence per day, without volume; a sighting stays apart from the exploitation claims and from CISA KEV. Filters: window (7|30, default 7), kev (0|1), limit (1..500).

The publication change stream: what this site published, stamped with OUR publish time (first_published, kev_added, detection_added, remediation_added). Pass since (YYYY-MM-DD, strictly-after) on the first call, then the returned next_cursor to continue. Optional cve scopes the stream to one CVE's change history. Events for withdrawn CVE ids are omitted.
