What is the Password Strength Scorer MCP Server?
Ask an AI if 'P@ssw0rd123' is a strong password. It will say 'yes — it has uppercase, lowercase, numbers, and symbols.' That's wrong. zxcvbn cracks it in under a second because it recognizes the pattern: 'Password' + common l33t substitutions + sequential numbers.
No AI can truly evaluate password strength. This MCP uses the Dropbox zxcvbn engine — the same algorithm trusted by 700M+ users — which performs real combinatorial analysis against dictionaries, keyboard patterns, dates, and l33t-speak.
The Superpowers
- Real Science, Not Rules: Doesn't check 'has uppercase + number'. Analyzes actual crack difficulty using pattern matching and combinatorics.
- 4 Attack Scenarios: Crack time estimates for online throttled, online unthrottled, local slow hash, and local fast hash.
- Actionable Feedback: Returns specific warnings ('Common l33t substitution') and improvement suggestions.
- 100% Local: The password never leaves the engine. Zero network calls. Zero data leakage.
Built-in capabilities (1)
The zxcvbn engine (created by Dropbox) detects common patterns, dictionary words, keyboard sequences (qwerty, zxcvbn), dates, and l33t-speak substitutions. It returns a score from 0 (very weak) to 4 (very strong), estimated crack times for different attack scenarios, and actionable feedback. No AI can truly evaluate password strength — this engine uses real combinatorial analysis. Evaluates password strength using the Dropbox zxcvbn engine. Returns a 0-4 score, crack time estimates, and improvement suggestions
Why Claude Code?
Claude Code registers Password Strength Scorer as an MCP server in a single terminal command. Once connected, Claude Code discovers all 1 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Password Strength Scorer data drives decisions without human intervention.

Frequently asked questions
Why can't my AI evaluate password strength?
AI checks superficial rules like 'has uppercase + number + symbol'. zxcvbn does combinatorial analysis — it knows 'P@ssw0rd' is just 'Password' with l33t substitutions, and rates it as weak despite passing every 'rule-based' check.
Is the password sent to any external server?
No. 100% local. The embedded dictionary and pattern matching engine run entirely in-process. Zero network calls, zero data leakage, zero risk.
What do the crack time numbers actually mean?
Four real attack scenarios: Online throttled (100/hour — most login pages), Online unthrottled (10/sec), Local slow hash (10K/sec — bcrypt), Local fast hash (10B/sec — MD5/SHA). Choose the scenario matching your system.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
