Perplexity

Handle the entire customer lifecycle.

Mastra AI lets you manage full customer accounts. You start by calling `create_accounting_customer` to add a new contact, and later use `get_customer_details` to retrieve their specific record. The workflow also supports cleanup. If an account is obsolete, the agent can run `delete_accounting_customer`. This action permanently removes the data from Wave.

Draft and finalize invoices in a single flow.

You'll build a process that first calls `create_draft_invoice`, giving it the customer ID and item details. Once that draft is ready, you can trigger `approve_draft_invoice`. This completes the transaction status change. This makes perfect sense for Mastra AI; if the invoice fails to approve, the workflow engine automatically retries or notifies an admin.

Retrieve and audit accounting data.

Need a history check? The agent can pull all necessary accounts using `list_accounting_invoices` or grab deep details on one invoice with `get_invoice_details`. This is great for auditing. For customer lists, running `list_accounting_customers` quickly gathers all names and IDs needed to start a new process.

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Wave Accounting tools become native Mastra tools.

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "wave-accounting-mcp-client",
  servers: {
    "wave-accounting-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});
