How to Use the DOD Contracts (FPDS) MCP in Vercel AI SDK

Q: How do I query DOD Contracts (FPDS) using Vercel AI SDK?

You pass the sQuery argument containing the DEPARTMENTID:"9700" filter into the searchcontracts tool. Your agent then executes the request and returns the XML payload to your React or Next.js component.

Q: Does Vercel AI SDK support filtering DOD Contracts (FPDS) by agency code?

Yes, include the AGENCYCODE:"9700" tag in your search string. This ensures the MCP server only returns relevant defense procurement records.

Stream real-time federal procurement data directly into your Vercel AI SDK interface without waiting for background tasks.

Perplexity

Direct access to federal procurement data

The `search_contracts` tool pulls raw XML records straight from the FPDS Atom feed. You get the data as it exists in the system of record. Your UI updates instantly as the Vercel AI SDK streams these results. Stop forcing users to stare at loading spinners while your app fetches contract details.

Filter DOD awards with surgical precision

Pass your department identifiers directly into the `sQuery` parameter to narrow down results. You control the scope of the data retrieval from your frontend. This keeps your payload small and your application fast. You only handle the specific contract records that matter for your current analysis.

Build live procurement dashboards

Connect this MCP server to your Vercel AI SDK project to visualize federal spending trends. You can map, sort, and display contract data as it flows into the client. This approach turns static procurement reports into active, queryable interfaces. Your users get the answers they need without leaving the application context.

Setup guide

Set up DOD Contracts (FPDS) 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 DOD Contracts (FPDS) 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 DOD Contracts (FPDS) transactions",
});

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