How to Use the Federal Register API MCP in Vercel AI SDK

Q: Can I check the health of the Federal Register API within Vercel AI SDK?

Yes. Call checkapistatus at the start of your request chain. If it returns false, your UI can alert the user before they waste time on a query.

Stream Federal Register API data directly into your Vercel AI SDK interface for real-time regulatory tracking.

Live Regulatory Data Streaming

Feed government data straight into your UI components using `search_federal_documents`. Your users watch findings appear as the AI processes them, removing the need for static loading spinners. This integration works perfectly with Edge Functions. You can pipe the output from the Federal Register API into your frontend state, keeping your application fast and responsive.

Agency Auditing Made Simple

Use `list_federal_agencies` to map out current government activity. You get a clean list of active bodies that you can use to filter document queries in your Vercel AI SDK projects. It’s straightforward to build a dashboard that tracks specific departments. You query the index, get the results, and render them immediately for your end users.

Full Document Metadata Access

Pull deep links and specific details using `get_federal_document_details`. When your agent identifies a relevant rule, you can present the source material instantly to the user. This tool gives you the raw metadata you need for citations. You won't have to guess where a regulation comes from when the data is right there in your component.

Setup guide

Set up Federal Register API 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 Federal Register API 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 Federal Register API transactions",
});

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

Common questions about Federal Register API MCP in Vercel AI SDK

You pass the tool definitions to your generateText call. Once the model selects `search_federal_documents`, the Vercel AI SDK handles the execution and streams the response back to your client.

Yes. Call `check_api_status` at the start of your request chain. If it returns false, your UI can alert the user before they waste time on a query.

The MCP server sends data as it arrives. Because you are using the Vercel AI SDK, you can pipe these results into your streamText handler without extra plumbing.

You configure the endpoint at the Vinkius level. Your project only needs the connection string, keeping your sensitive credentials out of your frontend codebase.

Vinkius runs this in an isolated sandbox. Only the public document requests you initiate leave the environment, and no personal user info is ever sent to the government endpoints.
