How to Use the Shippo MCP in Vercel AI SDK

Q: How does Vercel AI SDK handle rate comparisons with Shippo?

It streams the results live. When you call createshipmentgetrates, the rates appear in your UI as they come back, rather than making the user wait for a single loading spinner. It’s instant data feedback.

Q: What if I need to track a package using Shippo and Vercel AI SDK?

You simply use the trackpackagestatus tool call. This pulls real-time updates for any shipment. It's straightforward: input the tracking number, get the status.

Q: Can I save addresses using Shippo and Vercel AI SDK?

Yep. The listsavedaddresses tool lets you manage saved locations for repeat customers or internal use. This keeps your code clean because you don't have to re-validate the same address repeatedly.

Q: What type of data does this MCP Server handle regarding privacy?

This server touches shipping addresses and transaction IDs. Always treat that data like it is—it’s sensitive enough that you'll want to encrypt it end-to-end.

Q: Does Shippo support multi-carrier rate checking with Vercel AI SDK?

Absolutely. The createshipmentgetrates tool pulls rates from multiple top carriers, giving you the best comparison in one API call.

Getting Real Rates via MCP Server

Need to know the cost before you sell? You call `create_shipment_get_rates` and immediately get real-time shipping rates from multiple carriers. This tool compares costs across different zones, letting your user see the best option appear instantly in the UI. It’s perfect for building checkout flows where users need to compare USPS vs. FedEx prices before hitting 'buy.' The data streams directly into your React components via the Vercel AI SDK.

Processing Labels and Tracking

The core loop is simple: buy a label, track it later. Use `purchase_shipping_label` to handle payments and generate necessary tracking data for your order. Once that's done, you can call `track_package_status` to pull the latest status updates without needing another API key or endpoint. This two-step process lets you manage the entire fulfillment cycle—from purchase confirmation to delivery notification—all within one user flow powered by the MCP Server.

Handling Addresses and Listings

Before shipping, you gotta validate addresses. `create_and_validate_address` ensures the data your customer enters actually works for a carrier. You can also pre-fetch lists using tools like `list_saved_addresses` or check daily movements with `list_carrier_manifests`. It keeps your front end clean because you're doing all that dirty data checking and validation on the back end, passing only guaranteed good info to the user.

Setup guide

Set up Shippo 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 Shippo 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 Shippo transactions",
});

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