nvd_get_cveFetch one or more CVEs by ID from the NIST National Vulnerability Database. Returns CVSS scores across all available versions (v2.0, v3.0, v3.1, v4.0), CWE weakness classifications, affected CPE configurations, CISA KEV fields, and references. Up to 100 CVE IDs per call. For bulk lookups of more than 10 IDs, use brief: true — full records for 100 CVEs can exceed 1MB and exhaust context budgets.

nvd_search_cvesSearch CVEs by keyword, severity, CWE, date range, or CISA KEV status. The primary discovery tool for vulnerability surveillance and triage workflows. pubDays and lastModDays are convenience shorthands that expand to date pairs; values over 120 days are clamped to the NVD maximum and reported in queryMeta. Returns brief summaries — call nvd_get_cve for full detail on specific IDs. At least one filter is recommended; omitting all filters returns CVEs in default NVD index order (oldest first by CV
-
nvd_audit_cpeFind all CVEs affecting a specific product and version using CPE (Common Platform Enumeration). Requires either an exact CPE name (cpeName) or a partial match string (virtualMatchString) with optional version range bounds. With cpeName, NVD scopes results to configurations where the product is directly vulnerable, not merely referenced as a dependency. Use nvd_search_cpes first to resolve the correct CPE string for a product. Returns full CVE records.
-
nvd_search_cpesSearch the NVD CPE (Common Platform Enumeration) dictionary by product keyword or partial match string. Returns CPE names, human-readable titles, and deprecation status. Use before nvd_audit_cpe to resolve the correct CPE name for a product — CPE strings are precise identifiers (e.g., cpe:2.3:a:apache:http_server:2.4.51:*:*:*:*:*:*:*) and must match exactly to audit the right product.
-
nvd_get_cve_historyRetrieve the change history for a single CVE — CVSS score revisions, reference additions, status transitions (e.g., "Received" → "Analyzed"), and CPE configuration updates. Use when tracking a CVE's escalation or investigating when a score changed. For the current record, call nvd_get_cve instead. The NVD history endpoint is significantly slower than other NVD endpoints, especially without an API key — set NVD_API_KEY for reliable operation.
