Password MCP Tools for AI Agents

"Generate a secure password" — and your LLM responds with "Tr0ub4dor&3". LLMs generate passwords from memorized patterns, not from cryptographic randomness. These tools create truly random, secure passwords and accurately assess password strength.

All Password Tools (9)

Your agent gets access to 9 password tools via the /mcp/password/ endpoint. Here's the complete list:

Tool	Description
`password/analyze`	Analyze Password
`password/generate`	Generate Password
`password/generate-passphrase`	Generate Passphrase
`password/generate-pin`	Generate Pin
`password/hash-time`	Estimate Hash Time
`password/is-common`	Is Common Password
`password/suggest-improvements`	Suggest Improvements
`password/leetspeak`	Leetspeak Password
`password/memorable`	Generate Memorable

Agent Scenarios

Here's how real agents use these tools:

1. User provisioning agent

An IT agent generates secure temporary passwords when creating new employee accounts.

Tool Call: password/generate

{ "length": 16, "uppercase": true, "numbers": true, "symbols": true }

2. Security audit agent

A compliance agent checks if user passwords meet minimum strength requirements.

Tool Call: password/strength

{ "password": "MyP@ssw0rd123!" }

3. Onboarding flow agent

A registration agent validates that user-chosen passwords are strong enough before account creation.

Tool Call: password/strength

{ "password": "user-chosen-password" }

MCP Setup

Add password tools to your agent in under 2 minutes. Choose your client:

Claude Desktop / Claude Code

Add this to your MCP config:

{
  "mcpServers": {
    "tinyfn-password": {
      "url": "https://api.tinyfn.io/mcp/password/",
      "headers": {
        "X-API-Key": "your-api-key"
      }
    }
  }
}

Cursor

Go to Settings > MCP and add a new server:

Type: SSE
URL: https://api.tinyfn.io/mcp/password/sse
Headers: X-API-Key: your-api-key

Tip: Use the category-specific endpoint (/mcp/password/) for the best experience. The all-in-one endpoint (/mcp/all/) works too but has 500+ tools which some clients handle less efficiently.

When to Use These Tools

Use password MCP tools when your agent needs to:

Guarantee correctness — when wrong answers have real consequences
Process user data — when you're operating on actual user input, not hypothetical examples
Maintain consistency — when the same input must always produce the same output

You don't need these tools for casual conversation or rough estimates. Use them when precision matters.

Frequently Asked Questions

Why are LLM-generated passwords insecure?

LLMs generate passwords from learned patterns in training data. These passwords are predictable and may match common password patterns that attackers specifically test for.

How does TinyFn generate passwords?

TinyFn uses Python's secrets module with a cryptographically secure random number generator to produce truly random passwords with configurable character sets.

What does the password strength checker evaluate?

The strength checker analyzes password length, character variety, common patterns, dictionary words, and estimates crack time to provide a comprehensive strength score.
