What is the Password Strength Evaluator MCP Server?
When a Security Operations (SecOps) AI Agent audits a database of plain-text passwords or handles user creation, it needs to evaluate password strength. LLMs use subjective, probabilistic guessing which often approves weak passwords that bypass simple regex checks (like P@ssword1). This MCP solves that entirely.
The Superpowers
- Algorithmic Evaluation: Uses the industry-standard
zxcvbnengine to calculate true mathematical entropy, pattern matching, and dictionary analysis. - Crack Time Estimation: Returns the precise estimated time an attacker would need to crack the password via local fast hashing.
Built-in capabilities (1)
Pass the raw password string and receive a score (0-4), estimated crack time, and specific weakness feedback. Use the score to enforce minimum security policies. Algorithmsically evaluates password strength and estimates offline crack time. Essential for SecOps agents auditing user credentials

Password Strength Evaluator for Mastra AI
Every tool call from Mastra AI to the Password Strength Evaluator MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Is the password sent to any API?
No. The evaluation runs 100% local within the secure V8 Edge isolate, ensuring zero data leakage.
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.
Does it detect common patterns?
Yes, it detects dates, names, sequential keyboard patterns (like 'qwerty'), and common dictionary words.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
