Perplexity

Math-backed accessibility with OpenAI Agents SDK

Stop letting your agent guess at contrast ratios. This MCP Server runs the official WCAG 2.1 relative luminance formula to return exact data for your UI components. Your code invokes `check_color_contrast` to get the raw ratio and pass/fail status immediately. It keeps your production agent systems accurate and reliable.

Automated color auditing in your pipeline

Hardcode your agent to audit every color pair before it hits your production dashboard. This tool removes the guesswork that plagues standard LLM vision capabilities. Use the `check_color_contrast` output to trigger guardrails. If the ratio doesn't meet AA standards, your agent catches the issue before it deploys.

Structured compliance data for agent decisions

Your agent receives structured data back from `check_color_contrast` instead of vague text. It gets the precise ratio and specific compliance levels for both normal and large text. This lets your agent logic make binary decisions on design choices. It builds a safety layer into your interface testing routines.

Setup guide

Set up Color Contrast Checker Alternative 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 Color Contrast Checker Alternative tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Color Contrast Checker Alternative tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Color Contrast Checker Alternative 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="Color Contrast Checker Alternative Agent",
            instructions="You have access to Color Contrast Checker Alternative tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Color Contrast Checker Alternative MCP in OpenAI Agents SDK

Yes. You pass your CSS color values directly to the tool. It evaluates them against WCAG standards and feeds the result back to your agent.

It does. You connect the server and your agent discovers the tool automatically. It works as a standard function call within your Python code.

Models often hallucinate contrast values. This MCP Server uses a deterministic math engine to ensure your compliance data is never guessed.

You instantiate the server with your endpoint URL. The SDK handles the connection, letting you call the contrast tool as a native function.

The server only processes the specific HEX, RGB, or HSL strings you send for analysis. It does not store your design data or track your agent activity.
