Perplexity

Real-time inventory visualization

Stream current stock levels directly into your UI components. Use `get_stock` to pull data without blocking your main thread. Your users see the pantry status update the moment the AI agent processes the request. It turns a static list into a live feed within your application.

Automated shopping list updates

Add items to your list while the user types. The `add_shopping_list_item` tool executes instantly to keep your database current. Your frontend reflects these changes immediately through the SDK's streaming capabilities. No page reloads are required to see new items appear.

Chore management for frontends

Display household tasks that users can check off with a click. Call `execute_chore` to update the status in the backend while the UI handles the animation. This keeps your application state in sync with reality. You control exactly how the data flows from the Grocy (Home ERP) MCP Server to the browser.

Setup guide

Set up Grocy (Home ERP) 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 Grocy (Home ERP) 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 Grocy (Home ERP) transactions",
});

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

You manage access through your server endpoint. Ensure you use an authentication provider to verify requests before the agent runs any tools.

Catch the error in your tool call block. Log the failure and show a message to the user instead of letting the stream hang.
