How to Use the Zillow Alternative MCP in Mastra AI

Q: How do I manage a multi-stage valuation analysis with Zillow Alternative and Mastra AI?

You can create a workflow that first calls getzestimate, then uses the resulting ZPID to call getmonthlypayments. If the payment calculation fails, the system retries automatically.

Q: What is the best way to gather comparable sales data with Zillow Alternative and Mastra AI?

Use getdeepcomps within a workflow. This allows you to structure the process: get comps -> check status -> if insufficient, retry search using different criteria.

Q: Can I analyze regional trends with Zillow Alternative and Mastra AI?

Absolutely. Run getregionchart first. The workflow then waits for human approval (requireToolApproval) before proceeding to pull detailed demographics using getdemographics.

Perplexity

Handle Valuation Changes and Comps

When a user needs to analyze pricing, start by calling `get_deep_comps`. This returns rich data not just for the principal property but also all comparable sales. Since Mastra AI handles retries with exponential backoff, if one of your initial valuation calls fails, the workflow automatically tries again until it gets solid data.

Build Multi-Step Search Pipelines

A complex search needs multiple steps. Use `get_region_children` to find all neighborhoods in a city, then loop through those using `get_search_results`. Mastra AI manages this conditional branching. The framework ensures that if finding subregions fails, the workflow doesn't crash; it notifies an admin and waits for human input.

Generate Comprehensive Market Reports

To build a full market report, you need multiple data types. You can run `get_zestimate` to get the main valuation, then immediately follow up with `get_monthly_payments` using that ZPID. The workflow guarantees sequential execution: payments only calculate after the initial property value is confirmed.

Setup guide

Set up Zillow Alternative MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Zillow Alternative tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "zillow-alternative-mcp-client",
  servers: {
    "zillow-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Zillow Alternative Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Zillow Alternative tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Zillow Alternative transactions"
);
console.log(result.text);
