Perplexity

Stop date-math hallucination in your UI

This MCP Server stops your Vercel AI SDK application from failing at Brazilian holiday math. Regional holidays like those in Brazil cause standard LLMs to hallucinate dates constantly. By exposing `is_business_day` to your agent, you prevent your UI from showing incorrect SLA targets to your users. Your application gets the exact business day status instantly. The agent calls the tool behind the scenes, and the result streams directly into your React components without custom API endpoints.

Stream real-time SLA adjustments to the frontend

The `add_business_days` tool handles complex Brazilian date calculations right inside your Next.js application. When users adjust project timelines, your agent needs to calculate delivery dates on the fly. This integration lets your app display the correct date while skipping Brazilian national holidays. The streaming nature of the Vercel AI SDK means the user sees the recalculated timeline render in real-time. No loading spinners, just instant date math that respects Brazilian financial calendars.

Edge-ready date calculations with Vercel AI SDK

Edge-compatible tools like `is_business_day` keep your Vercel AI SDK application lightweight and fast. This setup runs perfectly in edge environments, allowing your agent to check dates without heavy third-party packages bloating your bundle. You simply configure the server URL, feed the tools to `streamText`, and let the edge runtime handle the rest. It keeps your interface snappy while maintaining strict regional accuracy.

Setup guide

Set up BR Business Days 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 BR Business Days 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 BR Business Days Calculator transactions",
});

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