Perplexity

Stream real-time lead searches to your UI

`search_leads` is the entry point for pulling active B2B contacts directly into your application's user interface. Your AI client calls this tool to scan targeted databases and stream the raw company listings back to the user instantly over the MCP transport. Instead of making users wait for a massive batch download, the Vercel AI SDK streams these records row by row. This means your interface displays matching prospects the millisecond they are found, cutting perceived latency to zero.

Instant email validation on the edge with this MCP Server

`verify_email` checks the validity of any corporate email address directly from your edge functions. This tool connects your AI client to Findymail's verification engine to run MX record checks and catch-all detection before you save data. Running this verification inside edge middleware keeps your app fast. The SDK handles the streaming responses so users see the verification status change from pending to clean in real time.

Live credit tracking and usage monitoring

`get_credits_summary` exposes your remaining Findymail API balance directly to your client-side interface. This tool lets your application monitor account limits before initiating expensive batch operations. By integrating this check into your streaming workflow, you can warn users when credits run low. The AI client queries the endpoint and updates the UI state dynamically, preventing failed API calls mid-session.

Setup guide

Set up Findymail 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 Findymail 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 Findymail transactions",
});

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

Common questions about Findymail MCP in Vercel AI SDK

Install the required packages using npm install ai @ai-sdk/mcp first. Initialize the client using createMCPClient with your Vinkius HTTP endpoint, then pass the tools array directly into streamText.

Yes, this MCP Server works in Edge environments because it relies on standard HTTP transport. You can invoke `verify_email` within your streaming API routes without worrying about Node.js runtime overhead.

The SDK processes each tool call individually as it streams. If you hit rate limits during bulk searches, the server returns standard HTTP status codes that your application can handle with custom UI alerts.

Yes, always call mcpClient.close() when your text generation finishes. This cleans up active connections and prevents memory leaks in serverless functions.

The MCP Server transmits B2B contact details and phone numbers through encrypted V8 isolates on Vinkius. No data is stored on our servers, and all API keys remain secured in your environment variables.
