CVSS Calculator MCP is a lightweight MCP server that enables AI agents to accurately calculate CVSS Base Scores and severity ratings. Supports CVSS 2.0, 3.0, 3.1, and 4.0 for vulnerability assessment, penetration testing, bug bounty hunting, and security reporting.
Check dependencies for known CVEs with EPSS and CISA KEV context. Read-only; free API token.
Fetches a public http(s) URL (GET, up to 5 redirects, 10s timeout, body never read) and grades its security headers A+ to F: score, present and missing headers (HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy), per-header findings with copy-paste fix values, and cookie flag issues. Passive, SSRF-guarded. Pay-per-call via x402 ($0.01 USDC on Base); initialize and tools/list are free.
Scan a site or AI-built app for exposed databases, keys and MCP endpoints, then verify the fixes.
Test your AI agents for security and safety weaknesses, and re-verify the fixes.
Authorized security scans, evidence, fix prompts and retests for AI-built web apps.
Security scans for AI-built web apps, starting with Lovable. Verify ownership, run authorized scans, inspect findings, get AI-ready fix prompts and request retests. Uses OAuth with a Guarita account. Fix prompt access follows the account plan.
