Perplexity

Search food databases instantly

Feed your application live macro data by calling `search_fatsecret_foods` within your streamText calls. The tool returns caloric and nutritional breakdowns for any keyword you pass from the UI. Your users get immediate feedback as the AI processes their queries. It removes the need for clunky search forms by piping results straight into your interface.

Pull detailed serving information

Use `get_fatsecret_food_details` to grab precise nutritional values for specific items. This MCP Server handles the lookup, returning serving size data that your Vercel-hosted app can display to the user immediately. You don't have to manage external databases or complex state syncs. The data flows from the API to your client-side components in one smooth motion.

Build faster nutrition tools

Connect this MCP Server to your edge functions to keep your application footprint small. Since it works with the standard MCP protocol, you spend less time writing glue code and more time building the UI. It handles the heavy lifting of data retrieval. Your code stays clean and your users get the nutrition facts they need without waiting on backend bottlenecks.

Setup guide

Set up FatSecret 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 FatSecret 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 FatSecret transactions",
});

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

Common questions about FatSecret MCP in Vercel AI SDK

Yes. You just pass the tools provided by this server into your generateText function. The SDK handles the communication automatically.

The data streams directly from the tool call to your frontend. Your components react to the incoming JSON payloads in real-time.

It is. The server uses standard HTTP transports that play nice with Vercel's edge environment.

The tool returns an empty set. You should handle this in your UI logic to prompt the user for a different search term.

This server only performs transient lookups. It does not store user health history or sensitive nutritional logs on our infrastructure.
