Perplexity

Live invoice monitoring in your UI

Feed your UI with live financial data by piping tool results into your stream. Use `list_invoices` to pull current records and display them instantly as your agent processes them. Your users won't see loading screens. They see the data appear the moment the MCP Server fetches it from your account.

Automated client management

Keep your records clean by pushing updates directly from your application logic. Use `create_client` to register new entities and `update_client` to modify existing profiles without manual entry. Validation happens at the source. The server ensures your data hits the portal correctly every time.

Service and tax tracking

Retrieve active tax configurations to ensure accurate billing calculations before generating documents. Use `list_taxes` to verify current rates and `create_item` to push service details into your catalog. Your application stays in sync with your accounting portal. No more guessing which tax IDs apply to new service items.

Setup guide

Set up InvoiceXpress (Online Invoicing) 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 InvoiceXpress (Online Invoicing) 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 InvoiceXpress (Online Invoicing) transactions",
});

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

Common questions about InvoiceXpress (Online Invoicing) MCP in Vercel AI SDK

You integrate the server using the createMCPClient method. Once connected, your agent calls the tools directly and streams the result into your frontend.

Yes, you catch errors directly in your TypeScript code. If a tool call fails, you handle the response object before it reaches the UI.

It does. The transport layer is designed to run in lightweight environments, keeping your response times fast.

You manage your endpoint token through the Vinkius dashboard. Your client holds the credentials securely throughout the session.

It accesses names, VAT numbers, and physical addresses stored in your account. This data stays within the encrypted transport channel between your agent and the portal.
