Automated WCAG guardrails in Mastra workflows

Build workflows that automatically flag bad color pairs before they hit production. When your agent generates a UI theme, Mastra runs `check_color_contrast` to verify compliance. If it fails, the workflow loops back to try a different palette. You get absolute reliability without writing complex logic. Mastra handles the retries and conditional branches, while this MCP Server handles the actual WCAG 2.1 relative luminance math.

Human-in-the-loop approvals for design fixes

Set up a Mastra agent that audits your design tokens. If `check_color_contrast` returns a fail grade for normal text, Mastra can pause the workflow and request human approval before applying a fallback color. This stops bad designs from slipping through. The agent gets the exact AAA or AA status from the MCP Server, allowing it to make highly informed recommendations to your team.

Resilient contrast auditing MCP Server integration

Deploy your accessibility checkers to any cloud with zero configuration headache. Mastra connects directly to this server using standard SSE or HTTP transports hosted on Vinkius. If a network hiccup occurs during an audit, Mastra's built-in exponential backoff ensures the `check_color_contrast` tool is safely retried. Your automated design pipelines stay up and running.

Setup guide

Set up Color Contrast Checker Alternative MCP in Mastra AI

Prerequisites

  • Node.js 18+ and a TypeScript project
  • @mastra/mcp + @mastra/core packages
  • Active Vinkius subscription with a valid endpoint token
  1. 1

    Install dependencies

    Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).

  2. 2

    Configure the MCPClient

    Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.

  3. 3

    Discover and inject tools

    Call mcpClient.listTools() and spread the result into your agent's tools object. All Color Contrast Checker Alternative tools become native Mastra tools.

  4. 4

    Run with any model

    Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts
import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "color-contrast-checker-alternative-mcp-client",
  servers: {
    "color-contrast-checker-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Color Contrast Checker Alternative Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Color Contrast Checker Alternative tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Color Contrast Checker Alternative transactions"
);
console.log(result.text);

Common questions about Color Contrast Checker Alternative MCP in Mastra AI

Install the Mastra MCP package and initialize the client with the Vinkius endpoint. From there, you can register the `check_color_contrast` tool directly into your Mastra agent or workflow steps.
Yes. If the agent gets a bad contrast ratio back, you can write a conditional branch in Mastra to automatically generate a new color pair and run `check_color_contrast` again.
AI models are terrible at math and cannot calculate relative luminance. This MCP Server gives your Mastra agents a reliable way to get real WCAG 2.1 compliance data.
Yes. You can configure Mastra to require manual approval whenever the contrast check tool returns a failing grade for large or normal text.
Vinkius processes your HEX and RGB inputs in a secure, ephemeral V8 sandbox. None of your design tokens or color codes are saved or stored on disk.
