How to Use the Unit Economics Calculator MCP in Mastra AI

Q: Does the MCP Server support advanced financial sequencing with Mastra AI?

Yes. You can chain tools together—for instance, running calculatecontributionmargin first, then using that result to feed into the payback period calculation.

Reliable Contribution Margin Calculations

The `calculate_contribution_margin` tool determines gross profit per customer. If variable costs change, or if the initial calculation fails, Mastra AI's workflow engine can automatically retry the financial math with defined backoff logic. This means your complex unit economics process runs reliably, even when external data sources hiccup.

Conditional Payback Period Modeling

Using `calculate_payback_period`, you can build a workflow that checks the initial payback result. If it's too long, the agent can conditionally trigger a follow-up action, like notifying an admin or running a different financial model. This multi-step control flow handles sophisticated unit economics scenarios far beyond simple API calls.

Human-in-the-Loop Health Checks

The `rate_health` tool provides the final LTV:CAC ratio health score. You can implement a human-in-the-loop check, requiring explicit approval before presenting this critical financial metric to your users. This added layer of control ensures that no major strategic decision is made based on an unverified unit economics reading.

Setup guide

Set up Unit Economics Calculator 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 Unit Economics Calculator 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: "unit-economics-calculator-mcp-client",
  servers: {
    "unit-economics-calculator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Unit Economics Calculator transactions"
);
console.log(result.text);

Common questions about Unit Economics Calculator MCP in Mastra AI

Yes. Because it supports multi-step workflows and retries, it's perfect for financial modeling that requires multiple checks—like calculating contribution margin followed by a payback period assessment.

It provides automatic retries with exponential backoff. If one part of your financial calculation fails due to transient errors, it automatically attempts the whole sequence again until it succeeds.

It's ideal. You can set up conditional branching: if the LTV:CAC ratio is below 3:1, notify a team member; otherwise, proceed with standard reporting.

Mastra AI handles Financial Metrics and Ratios. It processes raw inputs (revenue, costs) to output defined ratios like LTV:CAC.

Yes. You can chain tools together—for instance, running `calculate_contribution_margin` first, then using that result to feed into the payback period calculation.
