Real-time amortization tables in Vercel AI SDK

Feed your UI live amortization schedules using the `calculate_amortization` tool. It generates SAC or PRICE tables instantly, streaming the numbers straight to your React or Next.js components. Your users watch the schedule populate line by line. This removes the latency of traditional batch processing for complex loan tables.

Instant ROI calculations for Vercel AI SDK

Plug the `calculate_roi` tool into your streamText calls to get immediate percentage results. Your interface renders the output the moment the agent finishes the calculation. This keeps your users engaged with data that arrives as fast as the AI generates it. No hidden state or blocked threads.

Compound interest streaming in Vercel AI SDK

Update your financial dashboards with `calculate_compound_interest` results without refreshing the page. The Vercel AI SDK handles these tool responses as part of the standard stream. Your developers can now map complex interest growth curves directly into charts. It turns static inputs into dynamic, live-updating financial views.

Setup guide

Set up Finance Toolkit 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 Finance Toolkit 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 Finance Toolkit transactions",
});

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

Common questions about Finance Toolkit MCP in Vercel AI SDK

Install the MCP client package and initialize it with your server endpoint. You then pass the tool definitions directly into your generateText or streamText functions.

Yes. The SDK treats these tool outputs as standard asynchronous events. You can pipe the results into your UI state management immediately.

The server runs as a separate process. You connect to it via HTTP transport, which is fully compatible with Edge Runtime requirements.

The server operates in an ephemeral, isolated environment. It only processes the numeric inputs you provide for amortization or interest math.

You provide an auth header in your client configuration. This ensures that every request to the server is verified before the math runs.
