Scrutinize Pitches in Real-Time

Stop showing loading spinners. Use the `validate_founder_vision` tool to check a startup idea and stream the verdict directly into your UI. The Vercel AI SDK lets your users see the analysis unfold live as cohort retention and TAM calculations appear on screen. This isn't just about text. You can build interactive dashboards where a viability score changes in real-time as the Founder Vision Prover's analysis comes through. It’s the difference between a static report and a live diligence session.

Build Interactive Diligence Tools

The `validate_founder_vision` tool demands hard evidence: bottom-up TAM, real cohort retention, and a $0 CAC moat. With the Vercel AI SDK, you can build a form that feeds this data to the tool and streams the judgment back into your React components. This is perfect for building internal dashboards for VCs or accelerator portals for founders. You're not just showing a static pass/fail. You're showing *why* an idea fails, with data pulled from the MCP Server and rendered instantly on the edge.

Edge-Ready MCP Server Analysis

This MCP Server is all about brutal honesty. It rejects pitches with flimsy “1% of a $10B market” claims. Your frontend, powered by the Vercel AI SDK, can call this logic from an Edge Function, keeping your app fast and responsive. Connect your UI to the `validate_founder_vision` tool by passing the MCP client to `streamText`. You'll get the verdict on whether the unit economics are solid or if the payback period is a deal-breaker, streamed as it happens.

Setup guide

Set up Founder Vision 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 Founder Vision 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 Founder Vision Prover transactions",
});

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

Common questions about Founder Vision Prover MCP in Vercel AI SDK

You connect to the server using `createMCPClient` and pass its tools to `streamText`. The Vercel AI SDK handles streaming the `validate_founder_vision` analysis directly into your UI components, letting you build real-time feedback experiences.

Yes. You could build a “Pitch Grader” web app. Users enter their startup idea, and your Next.js app uses the AI SDK to stream the Founder Vision Prover's critique live on the page for instant feedback.

It's the real-time streaming. Instead of waiting for a full JSON response, you render the analysis—like TAM calculation, retention stats, and the final verdict from `validate_founder_vision`—as it's generated. This makes your UI feel alive and instant.

Absolutely. The Vercel AI SDK is framework-agnostic. You can stream the pitch analysis from the MCP tool into Svelte, Vue, or standard React applications just as easily.

Yes. Your pitch data, including TAM, retention numbers, and unit economics, is sent to the Founder Vision Prover's ephemeral sandbox on Vinkius. The connection is encrypted, and the Vercel AI SDK only manages the transport; your startup idea is not stored.
