Real-time data injection with Vercel AI SDK

Feed your UI live data by piping the `geolocate_ip` and `get_exchange_rate` tools into your streaming response. Your users watch the data populate the interface instantly instead of staring at a dead loading spinner. This MCP Server handles the handshake so you can focus on the component rendering. It keeps the connection open while the model processes the request.

Validate user input on the fly

Use `validate_email` inside your form handlers to catch typos before they hit your database. You'll see the validation result appear as the user types in the form field. It removes the need for custom backend validation logic. Just pass the input to the tool and let the agent handle the rest.

Business verification for your frontend

Check company details instantly using `validate_vat` during the checkout process. The tool returns the legal info so your React components can populate the invoice fields automatically. Everything stays in the Edge Function scope. You don't need extra API keys cluttering your client-side code.

Setup guide

Set up Abstract API 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 Abstract API 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 Abstract API transactions",
});

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

Common questions about Abstract API MCP in Vercel AI SDK

Install the MCP client package and point it to your Vinkius endpoint. Use the generateText hook to pass these tools to your model. It's standard TypeScript boilerplate.

Yes, the tool outputs stream directly into your UI components. You get the data in chunks as the model finishes its execution.

The SDK catches tool errors and lets you handle them in your catch blocks. You define the fallback UI for when a lookup fails.

Vinkius handles all the auth tokens at the transport layer. Your keys never touch the client code.

The server only processes the email string you send for validation. It doesn't store your user data or create long-term logs.
