nist-nvd-mcp-server
If you work on anything that ships dependencies, this is the server to reach for when you want Claude to answer vulnerability questions against live NIST data instead of stale training knowledge. It wraps the National Vulnerability Database with five tools: keyword and filtered CVE search (severity, CWE, CISA KEV status, date windows), batch CVE lookup up to 100 IDs, CPE dictionary search to resolve a product name, a CPE audit that lists CVEs affecting a specific product version, and CVE change history. The usual flow is search CPEs to get the exact product string, then audit that CPE against a version range, then pull full records for anything that looks serious. It runs over STDIO or Streamable HTTP, and a public hosted instance is available if you don't want to run it locally. Setting an NVD API key makes the slower history endpoint far more usable.
