How to Use the Hunter MCP in Vercel AI SDK

Q: How does Hunter work with the Vercel AI SDK?

You install the MCP client and pass the tools into your generateText call. It connects your app to the API endpoint and lets your agents execute commands.

Q: Can I use Hunter to verify emails inside a Vercel AI SDK app?

Yes. You pass emailverifier as a tool, and the AI agent runs the check against the domain whenever your code triggers it.

Hook up Hunter to your Vercel AI SDK projects to verify contact data and find professional emails in real-time.

Real-time email verification in Vercel AI SDK

Your front-end components can now trigger `email_verifier` the moment a user submits a form. The data streams directly into your UI, removing the need for clunky loading states. This gives your app immediate feedback on lead quality. You catch typos before they hit your database, keeping your outbound lists clean from the start.

Direct domain searching with Vercel AI SDK

Use `domain_search` to pull company-wide contact lists into your interface. Your AI client parses the results and displays them instantly in your React or Svelte views. It handles the heavy lifting of indexing public data. You get a list of prospects without ever switching tabs or manually querying a third-party site.

Stream lead data through Vercel AI SDK

Connect `list_leads` to your app to show saved contacts directly in your dashboard. Your agent fetches the latest entries, ensuring your users see the most recent data. This keeps your lead management internal. You control how the records appear, making the information usable for your specific business logic.

Setup guide

Set up Hunter 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 Hunter 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 Hunter transactions",
});

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