Live pedigree visualization with Vercel AI SDK

Feed your UI with live ancestry data using `get_person_pedigree`. Your users see the family tree build out as the agent fetches nodes, avoiding static loading states. Since this MCP Server works with streaming, the data flows to your Next.js components the moment the API responds. You get a fluid interface that feels fast and responsive.

Instant memory retrieval for React apps

Hook your frontend into `get_person_memories` to display photos and stories associated with specific ancestors. It pulls the media metadata directly to your client-side state. Keep your logic clean by passing the tool output straight into your render functions. No extra middleware is needed to format the raw API response for your users.

Search and verify identity in real-time

Run `search_persons` to find individuals and `get_person_details` to confirm their identity before rendering. The Vercel AI SDK handles the tool execution loop while you focus on the UI. This setup ensures your app stays in sync with the source of truth. If the data is missing, the agent knows immediately and can prompt the user for better search terms.

Setup guide

Set up FamilySearch API 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 FamilySearch API 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 FamilySearch API transactions",
});

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

Common questions about FamilySearch API MCP in Vercel AI SDK

Install the MCP client package and point it to your server URL. You then pass the tool definitions into your generateText call to let the model handle the API interactions.

Yes, but you must implement local caching to prevent hitting rate limits. Use the SDK state management to store previous results and avoid redundant network calls.

Absolutely. Because the server supports streaming, the tool results appear in your UI as soon as they arrive. This keeps your application snappy for the end user.

The server manages the token lifecycle. You just provide the endpoint, and the underlying transport handles the secure connection to the API.

The server only touches public genealogical records and specific user-authorized person IDs. Your data remains ephemeral and is never stored on our servers.
