View Historical Valuation Charts in Real Time

Need to show how property values have changed over time? Call `get_chart` or `get_region_chart`. You get a URL pointing straight to an image showing historical Zestimates. This is perfect for the UI. Because you’re streaming data with Vercel AI SDK, users see that graph appear live—no waiting for a loading spinner.

Analyze Comparable Sales Data

To give clients confidence in pricing, pull comparable sales using `get_comps`. This tool returns a clean list of recent sales the user can review. You can then layer on more detail by running `get_deep_comps`, which sends back rich data points for both the primary property and all the comps.

Get Current Market Rates and Demographics

Before showing a price, give them context. Use `get_rate_summary` to get current mortgage rates or run `get_demographics` for neighborhood stats. This data lets you build out the full picture right in your frontend component. You can even drill down into subregions using `get_region_children`.

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 Zillow Alternative transactions",
});

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