Block weak credentials in OpenAI Agents SDK

Your OpenAI agent shouldn't guess if a password is secure when it can call `score_password_strength` directly. This tool uses combinatorial analysis to catch keyboard patterns, dictionary words, and common dates. The agent handles the evaluation step during user registration or credential updates. Instead of writing complex regex that users bypass anyway, your agent gets a raw score from 0 to 4 to make immediate, data-backed decisions.

Real-time feedback with zero AI hallucinations

Evaluating entropy with the `score_password_strength` tool prevents your agent from hallucinating password safety. This MCP tool bypasses the model's guesswork by executing the zxcvbn engine directly. You get exact metrics on how long a brute-force attack would take across different scenarios. This raw data flows directly back into your agent's context, allowing it to explain to the user exactly why their password failed.

Trace password checks via OpenAI dashboard

Monitoring password checks is simple when your agent routes every request through the `score_password_strength` tool. Because this is integrated with the OpenAI Agents SDK, every single execution is fully traced and visible on your developer dashboard. This visibility makes it easy to debug agent handoffs when a user gets stuck in a registration loop. You see the exact failure point without exposing raw password strings in your application logs.

Setup guide

Set up Password Strength Scorer MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Password Strength Scorer tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Password Strength Scorer tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Password Strength Scorer tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Password Strength Scorer Agent",
            instructions="You have access to Password Strength Scorer tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Password Strength Scorer MCP in OpenAI Agents SDK

Install the SDK and spin up the MCP Server using your Vinkius HTTP endpoint. Pass the server configuration to your Agent constructor using the streamable HTTP transport parameter. The SDK auto-discovers the `score_password_strength` tool instantly.

No, this setup requires a connection to the hosted MCP endpoint. The SDK communicates with the server via secure HTTP streams to run the `score_password_strength` tool. This keeps your local agent environment lightweight and fast.

Yes, you can route users to a specialized security agent when a weak password is detected. The primary agent calls `score_password_strength`, reads the bad score, and hands off the session to a helper agent that guides the user through creating a better passphrase.

The tool returns a score from 0 to 4, estimated crack times for online and offline attacks, and specific feedback strings. Your agent uses these suggestions to tell the user what to change, like avoiding common dictionary words or sequential keys.

Yes, the plain text string is processed inside an isolated, ephemeral V8 sandbox on Vinkius. We do not log, store, or cache the passwords sent to the MCP Server. The data is analyzed in memory and immediately destroyed after the score is returned.
