Password Strength Analyzer API

br0ski777/password-strength-x402

Adds password security analysis directly into Claude. You get entropy calculations, crack time estimates, and checks against common password databases. The server runs remotely at password-strength.api.klymax402.com, so there's no local setup. Useful when you're building authentication flows, reviewing security policies, or need to validate password strength requirements in real time during a conversation. The implementation is straightforward: pass a password string, get back numerical scores and time estimates. The x402 suffix suggests this is part of a larger API ecosystem, though the GitHub repo itself is fairly minimal on documentation.
