Perplexity

Manage customer records in real time.

The `create_accounting_customer` tool lets your agent write new contact details, requiring just a name and email. You can then use `get_customer_details` to pull up any existing record when needed. The SDK makes this feel instantaneous. When you call `list_accounting_customers`, the results stream directly into your UI, showing users exactly which accounts are available without waiting for a loading spinner.

Draft and finalize invoices instantly.

Need an invoice drafted? Call `create_draft_invoice`, passing in the customer ID and an array of items. This action immediately generates a draft record inside Wave. Later, when everything is ready, use `approve_draft_invoice`. The tool moves that draft straight to an unpaid status, completing the workflow right on your front end.

Check and list accounting history.

Your agent can check what's going on with existing accounts using `list_accounting_invoices` or `get_invoice_details`. This gives you a full view of the invoice status, regardless if it’s paid or pending. If you need to know who your clients are, running `list_accounting_customers` instantly provides a list that streams into your interface for quick reference.

Setup guide

Set up Wave Accounting 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 Wave Accounting 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 Wave Accounting transactions",
});

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