Perplexity

Real-time Inventory Lookups

Call `get_inventory` to instantly check stock levels against current ERP records. Because you're using the Vercel AI SDK, users see the inventory data stream directly onto the webpage; no loading spinner needed. This real-time display makes your application feel fast and responsive. It’s perfect for building internal dashboards where immediate data visibility matters.

Displaying Customer Lists

Need to list customers? Just call `list_customers` via the Vercel AI SDK, and the results appear in your UI as they stream back. This handles large datasets without bogging down your front end. Build a client portal where users can see up-to-the-minute lists of suppliers or materials using this streaming capability.

Viewing Financial Records

You can fetch financial vouchers by calling `list_vouchers`. The Vercel AI SDK ensures that the list appears in your React component right as it's ready. This smooth stream makes data consumption look native. Use this to build a transaction history view. Users see each voucher detail populating on screen, which is much better than waiting for a single JSON dump.

Setup guide

Set up Yonyou / 用友 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 Yonyou / 用友 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 Yonyou / 用友 transactions",
});

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