Ground personas in actual interview data

Stop guessing who your customer is. Use `validate_customer_discovery` to force your agent to define users based on verified interview logs, specific job roles, and observed behavior rather than vague demographics. Your UI will stream the validation results in real-time. This lets you catch weak personas while they are still in the drafting phase.

Enforce The Mom Test during live chats

Stop asking users if they would pay for your idea. Pass your chat transcripts to `validate_customer_discovery` to flag leading questions and pivot toward uncovering past behaviors. This tool identifies when you are fishing for compliments. It forces you to ask about the last time a user encountered a problem and how they currently solve it.

Verify commitment signals over verbal interest

Verbal promises are not revenue. Use `validate_customer_discovery` to filter out vanity metrics and focus on hard evidence like pilot deposits or signed letters of intent. Integrate these findings into your React or Next.js frontends to show your team exactly which segments are ready to pay. It moves your product roadmap from assumptions to hard market data.

Setup guide

Set up Customer Discovery 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 Customer Discovery 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 Customer Discovery Prover transactions",
});

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

Common questions about Customer Discovery Prover MCP in Vercel AI SDK

Install the MCP package and initialize the client using your Vinkius endpoint. Pass the `validate_customer_discovery` tool into your `streamText` function to process interview transcripts directly in your workflow.

Yes. It forces you to document specific pain points before you commit to a build. By validating that a real segment has an urgent problem, you avoid spending months on features nobody wants.

It does. Because the tools stream results back, your app can provide immediate feedback on whether a user's interview notes provide enough signal to move forward.

The server applies The Mom Test to every submission. It rejects hypothetical questions and demands evidence of past behaviors and current workaround costs.

Your data stays within the ephemeral V8 Isolate sandbox managed by Vinkius. It only exists to process the current validation request and is not stored or shared.
