Cve Cache

Recent CVE + GHSA cache as a stdio MCP server.

Probe P-005 by weiseer.

What it does

Cached, structured snapshot of recent CVE + GitHub Security Advisory records — for AI agents auditing dependencies or screening new packages.

Your agent can:

• lookup_cve — full record for one CVE/GHSA ID
• find_for_package — all CVEs affecting a package by ecosystem (npm/PyPI/Cargo/Maven/Go)
• list_recent_critical — recent high-severity CVEs (default: 7-day, CVSS ≥ 7)
• severity_summary — counts by severity bucket

Why use this instead of your agent querying NVD itself

	Agent DIY	cve-cache
Source query	NVD JSON feeds + GHSA GraphQL	1 MCP call
Token cost (NVD records are large)	$0.05-0.20	$0 free / $0.00005 paid
Latency	2-10 seconds	<100ms
Cross-ecosystem normalization	Per-source schema	Pre-normalized
