Run multi-step profitability analysis.

Mastra AI handles the whole process. You can build a workflow that first runs `calculate_cac` to get cost data, then feeds those results into `calculate_ltv`. Finally, the agent calls `evaluate_profitability` to give you the full verdict. This ensures reliability because if one step fails, Mastra AI's built-in retries keep the whole process moving until it succeeds.

Process acquisition costs with graceful failure.

Need to analyze CAC across various channels? Start by using `calculate_cac`. If your input data is messy, don't sweat it. Mastra AI manages automatic retries and exponential backoff until the cost calculation succeeds. This makes complex financial reporting robust without constant human monitoring.

Model customer value with guaranteed execution.

The `calculate_ltv` tool figures out a customer's lifetime value based on ARPU, margin, and churn. Because this runs inside Mastra AI, you can set up human-in-the-loop approval before the final LTV figure is used. This is crucial when financial decisions are involved; you get confirmation before proceeding to profitability checks.

Setup guide

Set up LTV:CAC 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 LTV:CAC 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: "ltvcac-calculator-mcp-client",
  servers: {
    "ltvcac-calculator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent LTV:CAC Calculator transactions"
);
console.log(result.text);

Common questions about LTV:CAC Calculator MCP in Mastra AI

You define a workflow that sequentially calls all three tools. For instance, first calculating CAC using `calculate_cac`, then running LTV via `calculate_ltv`, and finally concluding with profitability.

Yes. The agent framework automatically retries tool calls, even if the input data requires multiple attempts to process correctly. This is key for reliable financial calculations.

The system accepts structured data like channel names and spend amounts for CAC, or core metrics like ARPU and churn rate for the LTV calculation.

It deals with financial records, including marketing expenditure (totalSpend), customer count (newCustomersAcquired), and various revenue metrics (ARPU, grossMarginPercentage).

It's built for it. You can build multi-step processes with conditional branching—for example, if the ratio is below 2:1, notify an admin.
