Key Capabilities

Stream instant valuations to your Vercel AI SDK UI

The `get_rental_valuation` tool calculates real-time rental estimates, feeding raw numbers straight to your user's screen. Your AI client pulls this data without forcing the user to stare at a blank loading state. By coupling `get_sale_valuation` with Vercel's streaming capabilities, you show property values step-by-step. Users see the exact comps and pricing models populate the interface as they generate.

Pull local rental comps directly in Edge Functions

The `get_rental_comparables` tool fetches active and historical neighborhood matches to justify pricing decisions. It runs inside lightweight Edge runtimes, keeping latency under 50 milliseconds during peak traffic. When your agent executes `get_sale_comparables`, it filters nearby sales by distance and square footage. This JSON payload feeds directly into your UI components without heavy backend processing.

Track local housing trends with this MCP Server

The `list_market_trends` tool retrieves localized real estate metrics using only a ZIP code. It gives your application immediate access to median listing prices and inventory shifts. You can combine this with `list_active_listings` to build dynamic dashboards that update as the agent researches. No complex database setup is required, since Vinkius secures the connection.

Setup guide

Set up RentCast 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. 1

    Install dependencies

    Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).

  2. 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. 3

    Discover and use tools

    Call mcpClient.tools() to auto-discover all RentCast tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.

  4. 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 RentCast transactions",
});

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

Common questions about RentCast MCP in Vercel AI SDK

First, install the required packages using npm. Then, initialize the client using createMCPClient with your Vinkius HTTP transport URL and pass the tools directly into streamText.
Yes, the server runs in a lightweight sandbox that is fully compatible with Edge runtimes. Your AI client can query get_rental_valuation through the MCP connection without hitting cold starts or timeout limits.
If get_property_details fails to find an address, the SDK receives a standard JSON error payload. You can catch this in your UI code to prompt the user for a corrected address format.
The list_active_listings tool lets your agent specify parameters like rental price ranges, bedroom numbers, and property types. The agent refines these parameters based on the conversation context before sending the API request.
Vinkius runs the server in an ephemeral V8 sandbox, meaning your RentCast API keys never leak to the client-side code. The real estate data, including specific property addresses and valuation results, is processed in memory and never stored on persistent disks.
