Password Strength Scorer

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)

score_password_strength

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

FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

How does LlamaIndex connect to MCP servers?

Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.

05

Can I combine MCP tools with vector stores?

Yes. LlamaIndex agents can query Password Strength Scorer tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.

06

Does LlamaIndex support async MCP calls?

Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
