How to Use the Accessibility Checker MCP in Mastra AI

Q: Can I manually intervene in the audit using Accessibility Checker with Mastra AI?

You can enforce human control using requireToolApproval. This stops the automated workflow mid-process, requiring your explicit sign-off before proceeding with final results or recommendations.

MCP Server for Multi-Step Compliance Audits

This MCP Server allows you to build complex, multi-step audits that handle failures gracefully. You can set up a workflow where the agent first calls `check_corridor_and_passage` and, if it fails, automatically triggers a secondary check using `check_doorway`. Mastra AI handles the retries with exponential backoff. This reliability is key for critical infrastructure checks. The system manages prerequisites; for instance, it won't attempt to assess ramp compliance (`check_ramp_compliance`) until initial pathway dimensions have been validated.

Mandatory Human Review with Mastra AI

For highly critical reports, you can use the `requireToolApproval` function on this MCP Server. This forces a human-in-the-loop review before any structural modification suggestions are finalized. The agent first runs checks like confirming bathroom size (`check_bathroom_spaciousness`) and then pauses, waiting for your explicit sign-off before reporting final compliance details.

Automated Workflow with the Accessibility Checker

You can design a sequence that automatically validates all core accessibility points. The agent starts by checking general passages using `check_corridor_and_passage` and then moves to specific entry points via `check_doorway`. This entire workflow runs reliably, even if one check needs retrying. It also manages the necessary checks for ramps (`check_ramp_compliance`) alongside confirming proper maneuvering room in restrooms. Mastra AI makes these complex dependencies manageable.

Setup guide

Set up Accessibility 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 Accessibility 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: "accessibility-checker-mcp-client",
  servers: {
    "accessibility-checker-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Accessibility Checker MCP in Mastra AI

Mastra AI automatically retries failed checks, ensuring your audit completes even if an initial tool call fails. It manages complex dependencies so that a required check always runs after its prerequisites pass.

Yes. The MCP handles compliance against both major international standards for all tools, including ramp slopes and passage widths. This ensures global applicability in your workflows.

The service touches building blueprints/dimensional measurements. Credentials flow through a zero-trust proxy, guaranteeing that your keys are used only during the transaction and never saved locally.

You can enforce human control using `requireToolApproval`. This stops the automated workflow mid-process, requiring your explicit sign-off before proceeding with final results or recommendations.

It processes dimensional measurements like minimum clear widths and maximum slopes. It also handles qualitative checks regarding maneuverability space in bathrooms and general passages.
