Evaluate raw entropy in VS Code Copilot

The `score_password_strength` tool lets your VS Code Copilot agent analyze raw password strings against known dictionaries, dates, and keyboard patterns. It uses the zxcvbn engine to calculate mathematical entropy. This integration allows your team to test security policies directly inside the editor. The MCP Server provides immediate feedback during development, preventing weak credentials from slipping into production.

Calculate real-world crack times

Executing the `score_password_strength` tool estimates the time required to crack a password under slow-hashing or fast offline attacks. Your VS Code Copilot agent can use these metrics to draft compliance documentation or write backend validation rules. You get clear data to justify password requirements to stakeholders. This eliminates arguments about which password rules actually matter.

Create clear error messages

Whenever the `score_password_strength` tool evaluates a string, it returns detailed suggestions when it flags weak credentials. It identifies specific issues like l33t-speak or common names. Your VS Code Copilot agent can parse these warnings to write descriptive UI feedback. This helps you build registration flows that guide users to create stronger passphrases.

Setup guide

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.

Common questions about Password Strength Scorer MCP in VS Code Copilot

Add the MCP Server details to a .vscode/mcp.json file at the root of your repository and commit it. Every developer on your team will automatically get access to the tools when they open the project.

No, the evaluation happens entirely on your local machine. The MCP Server executes the zxcvbn algorithm locally, so your password strings are never sent to external servers or telemetry endpoints.

Yes, you can ask the agent to run the tool on your config files. It will check your database passwords and flag any that do not meet the minimum strength score of 3.

No, it runs entirely offline. The zxcvbn engine uses built-in dictionaries and mathematical formulas, so you do not need any third-party credentials.

The server processes your password strings in an isolated memory space on your local system. No data is stored, cached, or written to disk, ensuring that your raw inputs disappear immediately after the evaluation completes.
