How to Use the Business Timezone & Holiday Scheduler MCP in Vercel AI SDK

Q: How do I handle country-specific holiday delays in Vercel AI SDK using the Business Timezone & Holiday Scheduler?

Pass the countryCode parameter to the addbusinessdays tool within your Vercel AI SDK tool call. The server queries the Nager.Date API to skip those specific national holidays automatically.

Q: What happens if an invalid IANA string is passed to the converter?

The converttimezone tool throws a clear error message specifying the bad string. Your agent catches this error and prompts the user to correct the timezone name.

Pipe real-time, holiday-aware scheduling math directly into your React components with the Vercel AI SDK MCP Client.

Stream Holiday-Aware Math in Vercel AI SDK

The `add_business_days` tool calculates future dates while skipping weekends and national public holidays via the Nager.Date API. Your Vercel AI SDK application sends the country code and day count, and the server outputs the exact target date. Instead of making your users wait for a full page reload, the calculated dates stream directly into your UI. This eliminates the lag when estimating shipping dates or delivery windows.

Instant Timezone Conversions on the Edge

The `convert_timezone` tool translates exact timestamps between IANA timezone strings like America/New_York and Asia/Tokyo. It processes these shifts instantly, giving your client application the exact local times. Because this MCP server runs on a lightweight V8 sandbox, your Edge Functions execute these conversions without cold-start delays. Your users see immediate, accurate local times in their scheduling dashboard.

Dynamic Calendar Feeds Without Spinners

The `add_business_days` tool handles complex regional calendars by checking the live holiday API. Your system passes the parameters, and the server returns the precise business day vector. You don't need to build massive local timezone databases or maintain holiday lists on your own server. Your Vercel AI SDK UI renders the calendar blocks as the data streams in.

Setup guide

Set up Business Timezone & Holiday Scheduler 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 Business Timezone & Holiday Scheduler 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 Business Timezone & Holiday Scheduler transactions",
});

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

Common questions about Business Timezone & Holiday Scheduler MCP in Vercel AI SDK

Pass the countryCode parameter to the add_business_days tool within your Vercel AI SDK tool call. The server queries the Nager.Date API to skip those specific national holidays automatically.

Yes, this MCP server connects via standard HTTP transport which works perfectly in Edge environments. You run the client setup inside your Next.js route handlers without Node.js dependencies.

The SDK uses streamText to call the tools and pipe the results directly to your React components. The UI updates the target date dynamically as soon as the server returns the calculation.

The convert_timezone tool throws a clear error message specifying the bad string. Your agent catches this error and prompts the user to correct the timezone name.

We never store your dates, country codes, or timezone strings. The Vinkius sandbox executes the request in an ephemeral V8 isolate and discards the execution memory immediately.
