Automated billing workflows with Mastra AI

Chain together `list_invoices` and `get_customer` to automate your entire collections process. Mastra AI manages the retry logic if an API call fails. Define clear branching paths for your agents. If a payment doesn't show up in `list_payments`, trigger a follow-up action automatically.

Human-in-the-loop invoice approvals

Require manual sign-off before your agent executes `create_customer` or sends an invoice. This keeps your accounting accurate while saving you hours of manual work. Set your agent to pause after generating an estimate. You review the output from `get_estimate` before it goes to the client.

Resilient multi-step accounting tasks

Use the server to handle series of tasks like listing items and generating invoices. The framework ensures that if one step fails, the workflow handles it with backoff. Focus on your business logic while the agent manages the sequence of `list_items` and document creation. It works in the background until the job is done.

Setup guide

Set up Invoicing Plus MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

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 Invoicing Plus tools become native Mastra tools.
4

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: "invoicing-plus-mcp-client",
  servers: {
    "invoicing-plus-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Invoicing Plus Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Invoicing Plus tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Invoicing Plus transactions"
);
console.log(result.text);

Common questions about Invoicing Plus MCP in Mastra AI

Install the MCP client package and add the Invoicing Plus URL to your agent's configuration. The framework automatically detects the available tools.

It does. You configure the agent's retry policy and it handles transient failures for any tool call, including invoice retrieval.

Yes, just enable tool approval in your agent setup. This forces the agent to ask you before it creates any new customer or invoice records.

Vinkius handles your tokens centrally. You just pass the endpoint to your agent, and the system manages the secure connection.

We use a zero-trust architecture. Your financial records are isolated in an ephemeral environment that clears immediately after your agent completes its task.
