Enforce REST standards in Vercel AI SDK

Your agent runs `validate_api_design` to stress-test your endpoint logic. It checks if your HTTP verbs match the intent and forces you to document the exact response envelope before you start coding. This prevents the common trap of shipping unversioned endpoints. You catch architectural gaps while the interface is still just a draft in your editor.

Real-time design feedback loop

The Vercel AI SDK streams these validation results directly into your console. You see the tool output as the agent processes your design specs. It handles the heavy lifting of checking your pagination limits and error contracts against RFC 7807 standards. You avoid expensive refactors by defining these rules upfront.

Automated endpoint contract checking

Stop guessing if your API design is ready for production. This MCP Server forces your agent to define a deprecation policy and versioning strategy immediately. Your frontend code stays clean because the backend contract is locked down. You integrate the tool results into your build flow to ensure no faulty designs reach your users.

Setup guide

Set up API Design Prover MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all API Design Prover tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent API Design Prover transactions",
});

console.log(text);
await mcpClient.close();

Common questions about API Design Prover MCP in Vercel AI SDK

It acts as a design gatekeeper. You pass the server tools into your agent, and it validates your schema definitions against REST best practices during the generation phase.

Absolutely. It ensures your internal endpoints follow consistent versioning and error reporting patterns, saving your team from documentation debt.

It expects you to provide the endpoint details so it can map them to HTTP verbs. It then critiques the design based on established industry rules.

No. The server only processes the design data you send during the validation call. It does not persist your endpoint definitions after the request finishes.

Your endpoint designs are ephemeral. The server processes the input in memory and discards it immediately after the validation tool returns its feedback.
