Perplexity

Search by attribute in Vercel AI SDK

Pipe the `search_retailers` tool directly into your streamText calls. You get raw JSON responses from the USDA database the moment the agent finishes the lookup. Your UI components update instantly as the data arrives. It keeps the user interface snappy while the backend handles the heavy lifting of parsing state and zip codes.

Geospatial queries for your AI client

Feed coordinates into the `search_retailers_by_location` tool to find nearby stores. It handles the radius logic so you don't have to write custom filters. This works perfectly with Edge Functions. You maintain low latency while letting the AI pull precise retailer lists for your users.

Direct MCP integration

Initialize the client using the standard transport setup. You gain direct access to the USDA dataset without writing middleware. Your code stays clean and maintainable. The tools map directly to your AI client functions for predictable data handling.

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 FNS SNAP Retailer Locator (USDA) 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 FNS SNAP Retailer Locator (USDA) transactions",
});

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

Common questions about FNS SNAP Retailer Locator (USDA) MCP in Vercel AI SDK

Install the MCP package and point your client to the Vinkius endpoint. Use the `search_retailers` tool inside your generateText function to pull store data.

Yes. Pass the latitude, longitude, and radius parameters to `search_retailers_by_location` to get a list of nearby vendors.

It does. The tool results stream directly into your UI components, avoiding the need for extra state management.

The server handles the request lifecycle. Your frontend just waits for the stream to complete or displays the partial data as it arrives.

Your coordinates are sent only to the USDA endpoint to perform the lookup. No persistent storage of user location occurs on our MCP server.
