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.
Triage a CVE: how severe it is, whether it is exploited, and how likely exploitation is.
Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and re
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.
Find hidden Unicode (zero-width, bidi, tag payloads), homoglyphs and lookalike names in text.
Test your AI agents for security and safety weaknesses, and re-verify the fixes.
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade.
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.
Security reviews, threat models over a repo or website, and remediation tracking, in your editor.
Operate simulations and inspect retained evidence with Firedrill.
Security scanner for MCP servers and skills: Unicode injection, patterns, secrets.
