Connect Password Strength Evaluator to ChatGPT and Claude

Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Stop letting your AI guess if a password is secure.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 1 capability

We ship only the actions that matter.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through zxcvbn.

  1. 01

    Evaluate password

    This capability calculates password entropy and returns a score from 0 to 4 along with estimated crack times. Your agent uses it to enforce security policies or audit credentials for specific weaknesses.

Real work

What teams actually run

01

Credential Auditing

An agent scans a database of existing passwords to find accounts with low entropy scores.

02

Automated User Onboarding

The agent checks new user passwords against a minimum score of 3 before allowing account creation.

03

Security Policy Testing

A developer uses the agent to verify if a new password policy is actually effective against cracking.

04

Password Generation Feedback

The agent evaluates generated strings to ensure they meet specific complexity requirements.

Automate a task

Put zxcvbn to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

zxcvbn works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put zxcvbn to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 1 capability arrives ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of zxcvbn, so you can see the experience inside your AI.

It does not authenticate your account with zxcvbn. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work zxcvbn owners hand off.

Security professionals who need to automate credential auditing and policy enforcement.

  • 01

    SecOps Engineers

    They hand off large batches of credentials to the agent for automated entropy auditing.

  • 02

    Security Researchers

    They use the capability to test the mathematical resilience of various password patterns.

  • 03

    DevSecOps

    They integrate the capability into automated user creation workflows to block weak passwords.

FAQ

Questions zxcvbn owners ask.

  • 01

    How is this different from a regex check?

    Regex only looks for specific characters like numbers or symbols. This MCP uses the zxcvbn engine to analyze actual entropy, dictionary words, and patterns, making it much harder to bypass.

  • 02

    What is the scoring range?

    The capability returns a score from 0 to 4, where 4 represents the highest level of strength.

  • 03

    Can my agent use this to enforce security rules?

    Yes. You can instruct your agent to reject any password that returns a score below a certain threshold.

  • 04

    Where does the crack time estimation come from?

    The estimation is based on the time an attacker would need to crack the password using local fast hashing.

  • 05

    Do I need to host this myself?

    No. Vinkius hosts and manages the MCP, so you just connect your client and it is ready to use.

  • 06

    Is the password sent to any API?

    No. The evaluation runs 100% local within the secure V8 Edge isolate, ensuring zero data leakage.

  • 07

    What is the score range?

    It returns a score from 0 (very weak) to 4 (very strong). We recommend rejecting any password with a score below 3.

  • 08

    Does it detect common patterns?

    Yes, it detects dates, names, sequential keyboard patterns (like 'qwerty'), and common dictionary words.
