How to Use the ExchangeRate- MCP in Vercel AI SDK

Q: Does ExchangeRate- support bulk queries in Vercel AI SDK?

It does if you are on a Business plan. Your agent can call getenricheddata to fetch localized currency profiles and bulk rates, then stream them to your frontend.

Q: How do I get a list of all active currencies?

You run getsupportedcodes through your agent. This returns a clean list of over 160 currency codes that you can feed directly into your UI dropdown menus.

Feed live global currency rates directly into your Vercel AI SDK streams without blocking your UI render thread.

Perplexity

Live rates streamed into Next.js using the MCP Server

The `get_latest_rates` tool lets your Vercel AI SDK client pull live currency rates immediately during a user conversation. By using `get_latest_rates` or `get_pair_conversion`, your application streams the actual exchange rates straight to the frontend, letting the user watch the calculations populate in real-time. This means you bypass the typical blank loading screens. The MCP Server feeds the numbers directly into the token stream, turning raw currency data into an active part of the conversational UI.

Historical comparisons in Vercel AI SDK charts

The `get_historical_data` tool fetches historical rates for specific dates to populate interactive charts in your Vercel AI SDK app. You do not need to write custom API fetch wrappers for every single currency pair. Your agent handles the query structure itself. It pulls the data via the MCP Server and passes it directly to your client-side charting components.

Active quota monitoring in Vercel AI SDK apps

The `get_quota` tool checks your remaining requests directly from your Vercel AI SDK runtime. Running public-facing apps means you have to watch your API consumption. This prevents runtime failures during high-traffic periods. The system can gracefully switch to cached data or warn the user when backend limits are close.

Setup guide

Set up ExchangeRate- 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 ExchangeRate- 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 ExchangeRate- transactions",
});

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

Common questions about ExchangeRate- MCP in Vercel AI SDK

You pass the tools array from the MCP client directly into streamText. The SDK lets your agent call `get_pair_conversion` when a user asks to convert prices, returning the raw rate instantly.

Yes, the server runs on the Vinkius MCP setup, meaning your Edge Functions only need to make standard HTTP calls. You initialize the client, call `get_latest_rates`, and close the connection when done.

It does if you are on a Business plan. Your agent can call `get_enriched_data` to fetch localized currency profiles and bulk rates, then stream them to your frontend.

You run `get_supported_codes` through your agent. This returns a clean list of over 160 currency codes that you can feed directly into your UI dropdown menus.

Vinkius processes your currency codes and API tokens in isolated V8 sandboxes. No query parameters or exchange rate requests are stored on disk, keeping your transaction volume logs private.
