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.
Triage a CVE: how severe it is, whether it is exploited, and how likely exploitation is.
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.
Check text before your agent reads it: hidden instructions, invisible text and links that leak data.
Scan a site or AI-built app for exposed databases, keys and MCP endpoints, then verify the fixes.
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.
Scan a website's HTTP security headers (HSTS, CSP, framing, COOP/CORP, cookies). Score + fixes.
Security reviews, threat models over a repo or website, and remediation tracking, in your editor.
Grades an MCP server's real egress: EVERY-HOP-VALIDATED, FIRST-HOP-ONLY, or OPEN-EGRESS.
Production-safety audits for AI-generated code, with a fix for every finding.
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).
Human-reviewed audit of a public website: bugs, passive security checks, UX. Order link for owners.
Argues against a security finding or a draft bug bounty report before you submit it.
Security tools for coding agents, with dependency advisory audits and structured remediation evidence. Free advisory intelligence is available; optional hosted security tools require an Offense API key and prepaid credit.
Scans an MCP server for security gaps before your agent connects. Free tier, no signup.
Free passive outside security scan of a live web app: leaked keys, exposed files, open Supabase
PII/secret redaction, email checks, sanctions screening, OSV lookups and an MCP server pre-check.
Audit any live URL: 85 SEO, AI-search, security, leaked-key and speed checks, with fixes to verify.
Run real, auto-recovered cloud attacks on AWS, Azure and GCP to test your defenses.
Scan a public GitHub repo, explain risks, get fix prompts and rescan to confirm fixes.
