Stream real-time visitor data into your UI

Your users don't want to wait for loading spinners while looking up sales targets. Use `get_visitor` to fetch raw company data and stream it straight to your React components. The SDK lets you pipe visitor details directly into the chat interface. You can immediately list page views using `list_page_views` to show exactly which pricing pages a lead browsed before they bounce.

Filter qualified leads instantly using the Vercel AI SDK

Stop wasting API calls on unqualified traffic. Have your AI agent call `list_qualified_leads` on the edge to isolate high-value accounts right inside your Next.js app. Once you isolate the target company, use `get_lead` to grab direct decision-maker contact details. The raw JSON streams directly into your UI cards, letting sales reps click to dial without page refreshes.

Track localized visitor intent on the edge

This MCP Server allows you to call `list_visitors_by_country` on the fly. Your edge functions can handle this routing to match incoming traffic with localized landing pages. If you need to dig deeper into specific sessions, call `get_session` to read the exact path the company took. It gives your sales team the context they need to write highly tailored cold emails.

Setup guide

Set up HappierLeads 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 HappierLeads 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 HappierLeads transactions",
});

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