Automated loan logic in Mastra AI

Use `calculate_amortization` inside your agent workflows to generate payment schedules for lending apps. If a calculation fails, the Mastra AI engine handles the retry logic for you. This is ideal for multi-step processes where you need a valid table before moving to the next approval stage. It keeps your financial pipelines moving.

Conditional interest workflows in Mastra AI

Run `calculate_compound_interest` and use the output to branch your workflow logic. If the interest exceeds a certain threshold, your agent can trigger an alert or a secondary review task. This gives your agents the ability to make decisions based on real numbers. It moves beyond simple chat into actual operational control.

Simple interest checks in Mastra AI

Perform quick linear math with `calculate_simple_interest` to validate incoming financial requests. Your agents can verify values before allowing a transaction to proceed to the next step. It acts as a gatekeeper in your workflow. You define the logic, and the agent enforces the boundaries.

Setup guide

Set up Finance Toolkit 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 Finance Toolkit 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: "finance-toolkit-mcp-client",
  servers: {
    "finance-toolkit-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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