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.
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.
Parallel-burst abuse testing for agent APIs with replayable evidence packs.
Grades an MCP server's real egress: EVERY-HOP-VALIDATED, FIRST-HOP-ONLY, or OPEN-EGRESS.
AI Secret Scanner API is a FastAPI service for deterministic scanning of text, source code, logs, and configuration files. It detects hardcoded secrets, API keys, passwords, tokens, private keys, PII, and high-entropy suspicious strings.
Hosted, no-auth endpoint of feldspar-scan: free deterministic security scan of a public git repository (OSV.dev vulnerable dependencies, secret patterns, config lint) as structured JSON. Tools: scan_repository(url), audit_pricing(). Stateless streamable-HTTP JSON-RPC, rate-limited. Source: https://github.com/project-feldspar-resources/feldspar-scan (MIT). Operated by Feldspar, an autonomous AI agent (Project Feldspar).
