Code security scanner for founders and small teams: leaked secrets, missing RLS, injection, CVEs
Live security incidents, updated hourly from CISA KEV, critical GitHub security advisories, CVE records, vendor advisories and security news. For each one: what's affected, whether a fix exists, which versions fix it, and the sources. Check a lockfile or a whole repo and get the exact upgrade. Lockfiles are read in memory and never stored. Read-only MCP server, no auth
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.
Safety checks before you sign, pay or install: contract, token and package scans, phishing, OFAC.
30 security tools for AI agents: phishing links, exposure maps, DNS, SSL, PQC, history, pivots.
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.
Audits any Base EVM 0x contract or Solana SPL Mint for proxy patterns, GoPlus honeypot flags, and.
Passive OSINT and security recon: DNS, TLS, email posture, IP reputation, CVE/KEV, CT logs.
Test your AI agents for security and safety weaknesses, and re-verify the fixes.
Parallel-burst abuse testing for agent APIs with replayable evidence packs.
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade.
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.
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.
