Key Capabilities
Stop broken specs from hitting Vercel AI SDK streams
Feeding a broken API spec to your streaming UI ruins the user experience. This MCP Server lets your application validate Swagger 2.0 or OpenAPI 3.x specs instantly using the `validate_openapi` tool. If a developer pastes a broken spec, the validator catches the exact structural path error before your streaming model tries to parse it. Your users watch the validation results stream in live instead of staring at a frozen loading spinner. By running this check directly inside your Next.js edge functions, you prevent invalid schema definitions from breaking downstream code generation.
Catch schema errors early in Edge Functions
Edge deployments require fast, lightweight execution without heavy external dependencies. The `validate_openapi` tool runs offline validation, returning clear error paths without making slow network requests to third-party validators. Your Vercel AI SDK agent can immediately render the exact line and path of a broken JSON schema. Keeping execution times low helps manage your serverless bills.
Stream schema feedback directly to the UI
Users get frustrated when they wait for a full build to fail just to find a missing comma in a spec. Integrating this MCP tool allows your UI to display validation paths in real-time as the user edits. The `validate_openapi` tool returns a structured list of errors that maps directly to the UI. Your Vercel AI SDK setup can render these issues immediately, making the debugging loop feel instantaneous.
Set up OpenAPI Validator Engine MCP in Vercel AI SDK
Prerequisites
- Node.js 18+ and a TypeScript project
-
ai+@modelcontextprotocol/sdkpackages - Active Vinkius subscription with a valid endpoint token
- 1
Install dependencies
Run
npm install ai @modelcontextprotocol/sdkplus your preferred model provider (e.g.@ai-sdk/openai). - 2
Create the Streamable HTTP transport
Use
StreamableHTTPClientTransportwith 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 OpenAPI Validator Engine tools. Pass them directly togenerateText()orstreamText()— 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.
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 OpenAPI Validator Engine transactions",
});
console.log(text);
await mcpClient.close(); Independent Platform Disclaimer: Vinkius is an independent platform and is not affiliated with, endorsed by, sponsored by, verified by, or otherwise authorized by @seriousme/openapi-schema-validator.
