What can you do with cve-cache?

  • 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

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @weiseer/cve-cache-mcp

  • 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
