npm mcp license

MCP server: generate strong passwords and score password strength with zxcvbn. Randomness comes from Node's crypto.randomBytes with rejection sampling so the distribution is uniform across the chosen alphabet.

Tools

generate

{ "length": 20, "exclude_ambiguous": true }

→ { "password": "aB3xK7nQ2wP9vR4zM8tL" }

At least one character from each enabled class is guaranteed.

→

{
  "score": 4,
  "guesses_log10": 17.34,
  "crack_time_display": "centuries",
  "warning": "",
  "suggestions": []
}

score is the zxcvbn 0-4 strength rating. guesses_log10 is the base-10 log of the estimated guesses needed.
