How to Use the LambdaTest MCP in Vercel AI SDK

Q: How do I handle large test logs using LambdaTest with the Vercel AI SDK?

Pass the output of gettestlogs directly to streamText. This prevents your serverless functions from hitting execution limits by sending raw log lines to the frontend as they arrive.

Q: Can I list active LambdaTest builds using Vercel AI SDK and this MCP Server?

Yes, you call listautomationbuilds through the MCP client to fetch and display the latest test runs. The SDK streams this structured JSON data directly to your React components for immediate rendering.

Stream real-time cloud test logs and session metrics directly into your React UI with LambdaTest and the Vercel AI SDK.

Live-streaming test log rendering in React

`get_test_logs` pulls raw execution data directly into your Vercel AI SDK stream using this MCP Server. Instead of making users wait for a massive log file to download, your UI renders the terminal output line-by-line as the LLM processes it. This setup bypasses the usual API loading spinners entirely. Your UI updates in real-time, showing developers exactly where their Selenium or Playwright script failed on the remote cloud node.

Dynamic browser matrix builder for Next.js

`list_supported_platforms` fetches active OS and browser configurations directly through the Vercel AI SDK. Your application uses this real-time list to populate dropdown selectors dynamically, preventing users from picking unsupported setups. When a user selects a platform, your agent immediately triggers the test run. The client handles the state transitions without lag, letting developers configure cross-browser matrices without writing custom API wrappers.

Instant status patching via MCP Server tools

`update_session_status` modifies the pass or fail state of a remote automation run directly from your chat interface. By pairing this tool with the Vercel AI SDK, developers can review a failure and mark it resolved without leaving their custom dashboard. The change reflects instantly on the cloud grid. This direct action loop keeps your local dashboard and remote test environments in sync without manual browser refreshes.

Setup guide

Set up LambdaTest 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 LambdaTest 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 LambdaTest transactions",
});

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

Yes, you call `list_automation_builds` through the MCP client to fetch and display the latest test runs. The SDK streams this structured JSON data directly to your React components for immediate rendering.

You configure your credentials on the Vinkius platform, which generates a single secure endpoint token. The SDK connects to this MCP Server proxy, keeping your private keys safe from frontend exposure.

Writing custom endpoints for every Selenium platform check takes hours. This server exposes ready-made schemas for tools like `list_supported_platforms`, letting your agent fetch live data in one step.

Your test execution logs and platform configurations pass through ephemeral V8 sandboxes. Vinkius never writes this data to disk, ensuring your proprietary test scripts and access tokens remain strictly private.
