How does this MCP calculate password strength?

It uses Shannon entropy to calculate bits of unpredictability and estimates the search space for brute-force attacks.

Can I check if a password follows my company rules?

Yes, the verify_policy_compliance capability checks if a password meets specific length and character class requirements.

What kind of patterns does the capability detect?

It identifies human-predictable vulnerabilities such as keyboard walks, sequential characters, and character repetitions.

Which AI clients can use this MCP?

You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

Does this MCP host the data?

Vinkius hosts and manages the MCP, so you only need to connect your client once to start using the capabilities.

How is password strength calculated?

Strength is determined using Shannon entropy, which considers the length of the password and the size of the character pool (uppercase, lowercase, digits, and symbols) to calculate bits of unpredictability.

Can I check if a password follows my company's security policy?

Yes. By using the verify_policy_compliance capability, you can specify requirements like minimum length and mandatory character classes to see if a password is compliant.

What kind of patterns does the auditor detect?

The audit_pattern_risks capability detects keyboard walks (e.g., 'asdf'), sequential characters (e.g., '123'), and repeated character sequences.

Connect Password Entropy Calculator 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. Measure mathematical password strength and detect human patterns.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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 · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Password Entropy Calculator.

01
Audit pattern risks
This capability scans for human-predictable patterns like keyboard walks or sequences. It finds vulnerabilities that simple entropy math might overlook.
02
Evaluate password strength
This capability calculates the mathematical strength of a string. It provides entropy bits and search space data to quantify unpredictability.
03
Verify policy compliance
This capability checks if a password meets your specific security requirements. It validates length and character class rules against a set policy.

Real work

What teams actually run

Credential Auditing

Run a batch of passwords through the MCP to find weak links in a user database.

Policy Validation

Verify that new user registration flows are enforcing the correct character requirements.

Pattern Analysis

Identify if users are choosing passwords based on common keyboard patterns.

Security Training

Show developers the mathematical difference between a weak and a strong password.

One connector, every AI

Password Entropy Calculator 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 Password Entropy Calculator 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.

Preview access · not provider authentication

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

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