How to Use the FMCSA Licensing & Insurance MCP in Vercel AI SDK

Q: How do I run FMCSA Licensing & Insurance queries inside a Next.js Edge Function using the Vercel AI SDK and this MCP?

You initialize the client with createMCPClient using an HTTP transport and pass the tools to streamText. This setup bypasses heavy Node.js runtimes, keeping your serverless execution times under 100 milliseconds.

Q: Can the Vercel AI SDK use the FMCSA Licensing & Insurance server to stream getcarrieroos directly to the UI?

Yes, it can. When your agent calls getcarrieroos, the Vercel AI SDK streams the raw out-of-service metrics directly to the client browser, allowing you to update your UI components in real-time.

Q: What is the best way to handle paginated searches using FMCSA Licensing & Insurance and Vercel AI SDK?

Use the searchcarriersbyname tool within your tool call loop. The SDK handles the iterative generator, allowing you to stream subsequent pages of carrier search results as they arrive.

Q: How do I close the MCP connection once the carrier check is complete?

Always call mcpClient.close() inside your API route's cleanup block or finally clause. Failing to close the connection can leak HTTP sockets on your serverless instances.

Perplexity

Verify authority live in Vercel AI SDK

The `get_carrier_authority` tool fetches active operating authority status from the federal database instantly. Your TypeScript code calls this tool inside `streamText` to let users see if a carrier is legally cleared to haul before the rest of the page even finishes rendering. You don't have to make users stare at a blank loading screen while checking dockets. Combining this tool with `get_carrier_by_dot` lets you render real-time federal compliance data block-by-block.

Run instant OOS and safety audits on the Edge

The `get_carrier_oos` tool pulls critical out-of-service safety data directly into your edge-compatible routes. This means your application can run quick compliance checks in under 50 milliseconds without dragging down your server performance. You can pair this check with `get_carrier_basics` to render safety ratings on the fly using this MCP Server. Drivers and brokers get immediate feedback on safety ratings without waiting for database roundtrips.

Live carrier search with zero UI lag

The `search_carriers_by_name` tool queries the federal registrar by Legal or DBA name and supports clean pagination. Your frontend handles the search input and streams matching carrier profiles directly to the user's viewport. You can chain this search with `get_carrier_cargo` to display exactly what materials each carrier is registered to haul. It makes building a fast, responsive broker portal straightforward.

Setup guide

Set up FMCSA Licensing & Insurance 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 FMCSA Licensing & Insurance 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 FMCSA Licensing & Insurance transactions",
});

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