Integer math for Mastra AI agents

Use `calculate_currency` within your Mastra AI workflow to handle money safely. The engine processes your operations as integers, eliminating the rounding drift that breaks financial records. Your agents can now perform multi-step math tasks without drifting off-course. It turns complex billing logic into a series of predictable, repeatable steps.

Workflow branching with accurate totals

Build conditional branches in Mastra AI that rely on rock-solid math results. If a total hits a specific threshold, the agent knows exactly what to do next. Because the tool is deterministic, your logic won't fail due to unexpected decimals. You define the flow, and the server provides the precise inputs needed to trigger it.

Automated financial error handling

Connect the server to your Mastra AI agent and let it manage your invoices. When you need to add or subtract tax, the tool ensures the math is perfect before the agent moves to the next task. This setup removes the need for manual checks. Your agents handle the arithmetic reliably, allowing your infrastructure to scale without financial drift.

Setup guide

Set up Currency Math Engine 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 Currency Math Engine 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: "currency-math-engine-mcp-client",
  servers: {
    "currency-math-engine-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Currency Math Engine transactions"
);
console.log(result.text);

Common questions about Currency Math Engine MCP in Mastra AI

You add the tool to your agent definition via the MCP client. Once imported, your Mastra AI agent invokes the math engine for any financial operation.

Absolutely, as the precise math results help your agent decide the next path. Your Mastra AI logic remains stable because the output is always an exact integer.

Yes, you can require human approval before the agent runs any calculation. This keeps your Mastra AI workflows under human control while the server handles the math.

You can add, subtract, multiply, divide, and format values. Each operation returns a clean, integer-based result for your agent to use.

We treat your currency inputs as ephemeral traffic. The server processes the math and discards the sensitive financial figures immediately, leaving no logs behind.
