How to Use the Color Contrast Checker Alternative MCP in Google ADK

Q: How does the Color Contrast Checker Alternative integrate with Google ADK?

You add it to your McpToolset. The agent then calls the function when it needs to verify if two colors meet compliance standards.

Q: Can I restrict which tools my Google ADK agent uses?

You can. Use the toolnames filter to limit what the agent can access. You can isolate the contrast checker to specific workflows.

Precise accessibility checks for Google ADK

Calculate contrast ratios using the strict WCAG 2.1 luminance formula. This MCP Server provides the hard numbers your agent needs to audit enterprise UIs. Call `check_color_contrast` with your UI values. It returns definitive pass/fail results for AA and AAA standards, giving your agent clear data to act on.

Enterprise-grade auditing for Gemini agents

Integrate color validation into your Google Cloud workflows. This server ensures your agents aren't just guessing at visual accessibility. By using `check_color_contrast` within your `McpToolset`, you get objective metrics. It integrates perfectly with your existing BigQuery or Vertex AI data pipelines.

High-accuracy compliance logic for your agents

Your agent gets granular feedback on contrast. It receives the calculated ratio and specific compliance status for different text sizes. This prevents accessibility regressions in your deployed applications. The tool provides the raw math needed to enforce your design system rules.

Setup guide

Set up Color Contrast Checker Alternative MCP in Google ADK

Prerequisites

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

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Color Contrast Checker Alternative tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Color Contrast Checker Alternative_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Color Contrast Checker Alternative tools via MCP.",
    tools=mcp_tools,
)

Common questions about Color Contrast Checker Alternative MCP in Google ADK

You add it to your `McpToolset`. The agent then calls the function when it needs to verify if two colors meet compliance standards.

It is. The tool provides the precise data your long-context agent needs to audit entire design files or stylesheets.

Vision models aren't calculators. This server uses an algorithmic approach to ensure your contrast ratios are mathematically correct every time.

You can. Use the tool_names filter to limit what the agent can access. You can isolate the contrast checker to specific workflows.

The server only reads the color inputs you provide to perform the calculation. No design metadata is logged or retained by the service.
