How to Use the Apperio MCP in Vercel AI SDK

Q: How do I connect Apperio to the Vercel AI SDK?

You'll use the Vinkius URL with the createMCPClient function. Just pass the URL in the transport configuration. The AI SDK then fetches the available Apperio tools for you to use with generateText or streamText.

Q: Can I build a UI to approve Apperio invoices with the Vercel AI SDK?

Yes, that's a perfect use case. Your agent can call the approveinvoice or rejectinvoice tools. Because the AI SDK streams results, you can update the UI instantly to show the new invoice status.

Build UIs that stream Apperio invoice and matter data in real-time with the Vercel AI SDK.

Live Invoice Dashboards

Stop making users wait for spinners. Stream Apperio invoice data directly into your React or Next.js components. Use `list_invoices` to populate a table, and as your agent gets details with `get_invoice_details`, the UI updates field by field. Your user sees everything happen live. They can watch as tags are applied with `tag_matter` or check an invoice's approval path with `get_invoice_approval_workflow`. It's a much better experience than waiting for a full API response.

Interactive Matter Management

Let users manage legal matters without leaving your app. Your agent can use `list_matters` to display all active cases, then fetch specific details with `get_matter_header` when a user clicks. Because the Vercel AI SDK streams tool results, your UI feels incredibly responsive. When a user wants to approve a bill, your agent calls `approve_invoice` and the status change appears on screen instantly.

Build with the Apperio MCP Server

Hooking up Apperio is straightforward. You get a single MCP endpoint from Vinkius that handles authentication. In your code, you just point the `createMCPClient` to that URL. Your agent gets access to all ten Apperio tools, from `get_account_check` to `reject_invoice`. You pass these tools to `generateText` and the AI SDK handles the rest, streaming results back to your frontend.

Setup guide

Set up Apperio 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 Apperio 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 Apperio transactions",
});

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