Run `evaluate_password` to get an immediate security score for any string. It calculates entropy and offline crack time directly in your local environment. Stop guessing if a password meets your standards. The tool returns specific feedback so you can force better compliance during your audit.

Local-first security analysis

Your credentials never leave the Claude Desktop sandbox. Since this MCP server runs as a local subprocess, your data stays on your machine. Use the `evaluate_password` tool to process sensitive strings without worrying about external API exposure. It provides enterprise-grade zxcvbn analysis locally.
