Add it to your agent

npx -y @smithery/cli@latest install cyanheads/nist-nvd-mcp-server --client claude

Swap --client claude for cursor, vscode, windsurf or another client. The CLI asks for any required settings.

A hosted server: nothing to install. Run /mcp in Claude Code to sign in if it asks.

Fetch 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.

Parameter	Type	Description
`brief`	boolean	When true, returns trimmed records (ID, status, top CVSS score, KEV name, published date) instead of full detail. Recommended for batches of more than 10 IDs.
`cveIds`		One CVE ID or an array of up to 100 CVE IDs to fetch.
`includeReferences`	boolean	When false, omits the references array to reduce response size.

Search 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

Parameter	Type	Description
`cweId`	string	Filter by CWE weakness ID (e.g., "CWE-79", "NVD-CWE-Other").
`limit`	integer	Maximum number of results to return (default 20, max 2000).
`offset`	integer	Zero-based page offset for pagination.
`kevOnly`	boolean	When true, filters results to CVEs in the CISA Known Exploited Vulnerabilities catalog.
`keyword`	string	Full-text search across CVE descriptions (AND-semantics across words).
`pubDays`	integer	CVEs published in the last N days (max 120; values over 120 are clamped). Mutually exclusive with pubStartDate/pubEndDate.
`severity`	string	Filter to CVEs at this CVSS severity level or above.
`noRejected`	boolean	When true (default), excludes CVEs with REJECT/Rejected status.
`pubEndDate`	string	ISO 8601 datetime for publication range end. Both pubStartDate and pubEndDate required together.
`lastModDays`	integer	CVEs last modified in the last N days (max 120; values over 120 are clamped). Mutually exclusive with lastModStartDate/lastModEndDate.
`pubStartDate`	string	ISO 8601 datetime for publication range start. Both pubStartDate and pubEndDate required together. Mutually exclusive with pubDays.
`lastModEndDate`	string	ISO 8601 datetime for last-modified range end. Both required together.

Find 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.

Parameter	Type	Description
`limit`	integer	Maximum number of CVEs to return (default 20, max 2000).
`cpeName`	string	Full CPEv2.3 name (e.g., "cpe:2.3:a:apache:http_server:2.4.51:::::::*"). NVD adds isVulnerable automatically. Mutually exclusive with virtualMatchString.
`versionEnd`	string	Upper version bound. Requires virtualMatchString.
`severityMin`	string	Filter out CVEs below this severity level.
`versionStart`	string	Lower version bound. Requires virtualMatchString.
`versionEndType`	string	Whether the upper version bound is inclusive or exclusive.
`versionStartType`	string	Whether the lower version bound is inclusive or exclusive.
`virtualMatchString`	string	Partial CPE match pattern (e.g., "cpe:2.3:a:apache:http_server:*"). Use with versionStart/versionEnd for version range audits. Mutually exclusive with cpeName.

Search 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.

Parameter	Type	Description
`limit`	integer	Maximum number of CPE entries to return (default 20, max 10000). If totalResults > returned, narrow the keyword for a more specific result.
`keyword`	string	Product name or vendor keyword (e.g., "apache http server", "openssl", "nginx"). At least one of keyword or cpeMatchString is required.
`cpeMatchString`	string	Partial CPEv2.3 pattern (e.g., "cpe:2.3:a:apache:http_server"). At least one of keyword or cpeMatchString is required.

Retrieve 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.

Parameter	Type	Description
`cveId`	string	CVE identifier to retrieve history for (e.g., "CVE-2021-44228").
`limit`	integer	Maximum number of change events to return (default 20, max 2000).
`offset`	integer	Zero-based offset for paginating through change events.
