Real-time bond pricing in your UI

Feed bond market data into your frontend components using `calculate_bond_valuation`. Your users get instant feedback on fair prices and YTM without waiting for background batch processes. This MCP pushes data through your Edge Functions, keeping your interface snappy. It turns raw bond metrics into live visual elements for your dashboard.

Currency yield conversion for global portfolios

Convert foreign yields into your base currency using `calculate_currency_equivalent_yield`. You can now show your users how UK Gilts or German Bunds perform compared to domestic holdings. Your application handles the math on the fly, updating the display as the user changes their target currency. It removes the need for manual lookups or stale static tables.

Inflation-adjusted return tracking

Calculate true purchasing power using `calculate_inflation_adjusted_return`. It strips away nominal gains to show the real value of sovereign debt investments. This adds depth to your financial tools, giving your users a clearer picture of their long-term wealth. You present the final adjusted figures directly in your React or Svelte views.

Setup guide

Set up Treasury Return Calculator 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 Treasury Return Calculator 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 Treasury Return Calculator transactions",
});

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

Common questions about Treasury Return Calculator MCP in Vercel AI SDK

Install the MCP client via npm and point it to the Vinkius URL. Once connected, your Vercel AI SDK agent can invoke the calculator tools directly from your route handlers.

Yes. The tool output streams back to your frontend, allowing you to render the valuation data as soon as the agent returns a result.

It handles USD, GBP, and EUR conversions natively. You pass the currency code to the tool, and your Vercel AI SDK app receives the adjusted yield immediately.

You manage the lifecycle via your application code. Open the connection when the user needs financial analysis and ensure you close the transport after the operation finishes.

The calculator only processes the specific bond parameters you send. It does not store your user's sensitive financial records, ensuring that transaction data remains within your local runtime environment.
