Perplexity

Mastra AI design validation workflow

Embed the `validate_api_design` tool into your Mastra agent to catch flaws early. The agent inspects your verbs and error contracts before the workflow moves to the deployment stage. If the design fails the check, the agent stops the process. This prevents bad API specs from reaching your cloud infrastructure.

Hardened API contracts

You configure your Mastra agents to enforce RFC 7807 standards automatically. Every endpoint you design gets checked for proper pagination and versioning headers. This creates a consistent interface for your services. You reduce debugging time since the agent catches semantic errors at the design phase.

Automated design guardrails

Use the tool to force a clear deprecation policy on every new endpoint. Your agents check these rules against the REST Design Rulebook. This ensures your multi-step workflows remain stable. You don't have to manually verify every field in your response envelopes anymore.

Setup guide

Set up API Design Prover 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 API Design Prover 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: "api-design-prover-mcp-client",
  servers: {
    "api-design-prover-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent API Design Prover transactions"
);
console.log(result.text);

Common questions about API Design Prover MCP in Mastra AI

You add the server to your agent configuration. Once connected, your agent uses the design tool to verify API structures before executing further steps.

Yes, it acts as a validation step. If your design doesn't meet the specified REST standards, the agent halts, ensuring only valid designs proceed.

It enforces RFC 7807 by default. You can define your specific fields within that structure to keep your error responses consistent across all services.

Your design specifications are never stored. The server runs in a sandbox and clears all memory after the validation task is complete.

Yes. The server treats your endpoint definitions as transient data. It does not track, log, or save any details about your API surface.
