Trigger load tests from your UI

Trigger your performance scenarios immediately using `run_scenario`. Your AI client sends the request, and the results stream back into your interface as they happen. Stop waiting for static reports. Use `get_test_run_stats` to feed live performance metrics into your React or Next.js components, giving your users real-time visibility into system behavior.

Manage account limits with your AI client

Keep your VU consumption under control by checking your quotas before launching new tests. Call `get_account` to pull current subscription details directly into your application logic. Avoid surprise overages by verifying your limits programmatically. Your AI client handles the logic, ensuring you only execute tests when your account capacity allows it.

Monitor active test runs in real-time

Track the status of ongoing executions by calling `list_test_runs` inside your streaming response. This keeps your dashboard updated without requiring page refreshes. If a test goes sideways, use `stop_test_run` to kill the process instantly. You maintain full control over your infrastructure costs through your own code.

Setup guide

Set up LoadNinja (Real-Browser Load Testing) 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 LoadNinja (Real-Browser Load Testing) 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 LoadNinja (Real-Browser Load Testing) transactions",
});

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

Common questions about LoadNinja (Real-Browser Load Testing) MCP in Vercel AI SDK

You connect by using the @ai-sdk/mcp package. Point your client to the Vinkius endpoint, and your AI client will gain direct access to the full suite of LoadNinja tools.

Yes. Because the Vercel AI SDK supports streaming tool outputs, performance metrics appear in your UI as the MCP server returns them. You don't have to wait for the entire test to conclude before seeing the data.

It does. You can write scripts that trigger tests and monitor stats directly from your backend routes or edge functions. This allows for performance checks on every deployment.

Vinkius handles the complexity for you. You just need to provide your endpoint token when initializing the MCP client in your Vercel AI SDK project.

Your test run details, including scenario IDs and VU statistics, remain strictly within your authenticated session. We enforce isolation between users, ensuring your performance data stays yours.
