How to Use the AbstractAPI MCP in Vercel AI SDK

Q: How do I install the AbstractAPI toolset in my Vercel AI SDK project?

Install @ai-sdk/mcp and ai via npm first. Then, establish a connection using createMCPClient pointing to your Vinkius endpoint. Pass the tools directly to streamText to let your agent call them.

Q: How does the AbstractAPI email validation tool prevent latency in Vercel AI SDK?

The validateemail tool runs its SMTP check asynchronously through our hosted server. Because Vercel AI SDK streams responses, the validation results display in the UI the exact millisecond they resolve. Your users never stare at a frozen screen.

Q: How does this server handle the privacy of IP addresses and emails?

Data processed by geolocateip and validateemail runs through ephemeral V8 isolates. Vinkius never stores the raw IP addresses, email strings, or phone numbers queried by your application. Every transaction is processed in memory and wiped immediately.

Fetch real-time company data, verify emails, and geolocate IPs directly inside your Vercel AI SDK streaming interface.

Perplexity

Validate emails and phone numbers on the edge

`validate_email` verifies inbox existence using MX records and SMTP checks before you send a single message. This tool gives your app immediate deliverability scores to filter out fake signups. Your user sees this happen live as they type. Next, `validate_phone` checks the carrier and line type of any international number. It flags landlines versus mobile phones instantly. Your Vercel AI SDK frontend renders these validation states without waiting for a backend reload.

Enrich lead data instantly using this MCP Server

`enrich_company` extracts employee counts, industry types, and LinkedIn profiles using only a domain name. Your agent calls this tool to populate dashboard fields on the fly. No manual entry required. Combine this with `validate_vat` to confirm European tax registrations during checkout. The tool pulls registered company names and legal addresses directly from EU databases. It inserts the verified billing details straight into your customer's invoice form.

Grab screenshots and geolocate users

`website_screenshot` generates a permanent URL of a full-page headless browser capture of any live site. Your AI client grabs this image and displays it directly in the chat stream. It gives users immediate visual feedback of external links. Meanwhile, `geolocate_ip` maps IPv4 or IPv6 addresses to physical locations, ISPs, and local currencies. This tool lets your edge functions customize the UI based on where your user is sitting. You get exact regional settings without complex database lookups.

Setup guide

Set up AbstractAPI 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 AbstractAPI 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 AbstractAPI transactions",
});

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