How to Use the HUD Fair Market Rents MCP in Vercel AI SDK

Q: Can Vercel AI SDK handle statewide HUD Fair Market Rents?

Yes, use the getstatefmrdata tool within your agent definition. It returns the full list for a specific state code, which you can then parse in your UI.

Stream official HUD Fair Market Rents directly into your Vercel AI SDK frontends for live, data-driven housing analysis.

Real-time FMR data streaming in Vercel AI SDK

Feed your UI with live housing metrics by hooking this MCP Server into your streamText calls. Your components update as the AI processes the response, removing the need for static loading screens. Use `get_fmr_data` to pull precise rental benchmarks directly into your React or Next.js dashboard. It keeps your interface responsive while fetching HUD data in the background.

Dynamic income limit lookups for your frontend

Expose `get_il_data` or `get_mtsp_il_data` to your agent to provide instant eligibility checks for users. The data flows from the server to your view layer without extra middleware. Your application handles user queries about income thresholds using the raw JSON outputs. It keeps the logic centralized in your SDK code.

Geographic filtering for HUD data

Navigate through `list_states`, `list_counties`, and `list_metro_areas` to let users drill down into specific housing markets. The SDK handles the tool calls, allowing your UI to build dynamic dropdowns based on real-time API responses. This keeps your application state in sync with the current HUD catalog. You spend less time writing fetch logic and more time displaying the actual data.

Setup guide

Set up HUD Fair Market Rents 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 HUD Fair Market Rents 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 HUD Fair Market Rents transactions",
});

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

Common questions about HUD Fair Market Rents MCP in Vercel AI SDK

You initialize the client via the HTTP transport and pass the tools into your generateText function. Once the agent selects a tool like `get_fmr_data`, the result streams back to your frontend.

Yes, use the `get_state_fmr_data` tool within your agent definition. It returns the full list for a specific state code, which you can then parse in your UI.

The data is pulled directly from official HUD endpoints. The server acts as a pass-through to ensure your Vercel AI SDK application always reads the latest published numbers.

Vinkius handles the connection. You just provide the endpoint token and the server manages the authentication requirements for the HUD data.

All requests pass through a secure, ephemeral V8 isolate. Your specific queries for rental data are never logged or stored by the server infrastructure.
