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
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.
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.
