Automatically detect and parse package files (package.json, requirements.txt, Gemfile, go.mod, pom.xml) and check all dependencies against the CVE database. Use when you want to audit a project for security vulnerabilities, check if dependencies have known CVEs, or generate a vulnerability report for compliance.
Search for Common Vulnerabilities and Exposures (CVEs) by ID (e.g., CVE-2024-1086) or by product name (e.g., OpenSSL, Apache Tomcat). Get detailed vulnerability information including severity scores, affected software versions, and references. Use when the user wants to look up CVE information, check if a product has known vulnerabilities, or research security issues.

When no Gravatar found:
Checking: nonexistent@example.com
✗ No Gravatar found
Hash: abc123def456789...
This email does not have a Gravatar image.
A default image will be shown.
Check if developer has Gravatar:
npx tsx scripts/check.ts beau@dentedreality.com.au
Bypass cache for fresh check:
npx tsx scripts/check.ts user@example.com --no-cache
Check if an email is associated with a Gravatar profile:
npx tsx scripts/check.ts contact@company.com
Check multiple team members:
for email in dev1@company.com dev2@company.com; do
npx tsx scripts/check.ts "$email"
done
Verify Gravatar exists before displaying avatar in UI:
npx tsx scripts/check.ts user@example.com && echo "Show Gravatar" || echo "Show default"
Results are cached for 24 hours. Since Gravatars change infrequently, caching improves performance while maintaining accuracy.
Use --no-cache when you need real-time verification.
