Format conversion for OpenAI Agents SDK

`convert_color` takes any CSS color string and instantly returns the HEX, RGB, and HSL equivalents. Your agent doesn't guess syntax. It hands off the raw string and gets back exact mathematical conversions. Building production systems requires strict constraints. You configure guardrails in the OpenAI dashboard to validate these outputs before they hit your frontend. The agent handles the translation, while the framework ensures safety.

Mathematical palette generation

`generate_color_palette` accepts a base color and a mode to compute a mathematically perfect palette. Your specialized design agent runs the math without relying on subjective visual models. You pick between analogous or complementary schemes. You track every tool call directly in your tracing logs. When a handoff happens between your layout agent and your styling agent, the exact palette parameters remain visible. No hallucinated hex codes ruin your UI.

Precise luminance control via MCP

`manipulate_luminance` shifts a color's lightness up or down based on a strict percentage. Pass a positive integer to lighten or a negative one to darken. The tool adjusts the HSL value directly. This MCP Server eliminates manual contrast checking. Your agent computes the exact shift needed for hover states or active buttons. The operation executes instantly, keeping your multi-agent workflow moving.

Setup guide

Set up Deterministic Color Engine 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 Deterministic Color Engine tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Deterministic Color Engine MCP in OpenAI Agents SDK

Instantiate MCPServerStreamableHttp using the MCPServerStreamableHttpParams class and your endpoint URL. Pass it via the mcp_servers array when building your Agent. Set cacheToolsList=True to speed up initialization.

Yes. You define strict guardrails within your agent configuration. When the engine returns a computed palette, the framework checks the payload structure before executing the next step.

Agents use the luminance tool to calculate precise contrast ratios mathematically. They don't guess hex values. They compute exact percentages to meet WCAG standards.

No. The agent auto-discovers all three tools at runtime. You simply provide the MCP connection context manager and the framework handles the rest.

No. This server only processes raw color strings like HEX codes or HSL values in memory. The V8 Isolate Sandbox destroys the environment immediately after returning the calculation, leaving zero trace of your brand colors.
