Mastra AI workflow accessibility integration

Add `check_color_contrast` to your agent workflows to automate design audits. Mastra AI can trigger these checks whenever a new design token is generated. If a color combination fails the WCAG ratio, your agent can catch the error immediately. It prevents non-compliant designs from reaching production.

Conditional logic for visual compliance

Create branches in your code using `check_danger_text_contrast`. If the error text is unreadable, your agent can automatically adjust the color values. This turns accessibility into a programmatic task. Your agent handles the iteration until the colors pass the standard thresholds.

Multi-step design validation

Sequence `check_text_on_pure_white` and `check_text_on_pure_black` to validate your entire library. It ensures your design system remains consistent across all states. Mastra AI manages the retries and error handling for these calls. You get a reliable way to verify your visual assets at scale.

Setup guide

Set up Color Contrast Checker 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

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

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Color Contrast Checker tools become native Mastra tools.
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-mcp-client",
  servers: {
    "color-contrast-checker-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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