Real-time metric streaming with Vercel AI SDK

Feed your actual and predicted arrays into the `calculate_confusion_matrix` tool to get instant feedback. Because this runs on Vercel AI SDK, the results appear as they compute, removing the need for clunky loading states in your dashboard. Your users need to see accuracy and F1-scores as the model runs. This setup pushes the data straight to the frontend so your React or Next.js components update without a page refresh.

Math you can trust for model evaluation

LLMs often struggle with basic arithmetic, leading to fake evaluation stats. This MCP Server forces the logic into a deterministic calculation path that ignores the AI's internal guessing. By passing your data to `calculate_confusion_matrix`, you get raw values back. You'll see precise True Positives, False Positives, and Recall figures that you can actually rely on for deployment decisions.

Edge-ready performance metrics

The server plays nice with Edge Functions, ensuring your evaluation logic doesn't bloat your cold start times. It keeps your Vercel AI SDK implementation fast and lean. Just install the client and call the tool. You'll have a direct pipeline from your raw model outputs to a clear, actionable confusion matrix in your production interface.

Setup guide

Set up Confusion Matrix Engine 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 Confusion Matrix Engine 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 Confusion Matrix Engine transactions",
});

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

Common questions about Confusion Matrix Engine MCP in Vercel AI SDK

It gives you a hard math tool to replace shaky LLM-generated stats. You call it, get the numbers, and display them instantly.

Yes, it's built to handle live data streams. Your production UI will reflect the calculated accuracy the moment the tool returns the data.

Absolutely. Since the tool returns structured JSON, your streaming response handles the output just like any other text or data stream.

It is. The calculation is local and direct, so it adds almost zero latency to your agent's response time.

No. The server only processes the label arrays you send it. It doesn't log your model inputs or predictions anywhere.
