Automated retirement planning

Connect `calculate_milestones` to your agent workflows to automate complex long-term projections. If your agent detects a change in market assumptions, it can trigger a recalculation immediately. This keeps your financial plans current without manual intervention. It turns a static calculation into a living, breathing part of your agent's infrastructure.

Conditional lifestyle adjustments

Use `get_lifestyle_targets` to build branching logic in your agents. If the required capital exceeds the user's current trajectory, the agent can automatically suggest lifestyle changes. This allows your workflow to handle failures gracefully. It shifts the burden of adjustment from the user to the agent.

Reliable contribution simulations

Implement `simulate_contribution_impact` within your workflows to test various savings scenarios. Your agent can run these simulations in the background and notify the user of the best path forward. Because Mastra AI supports retries, your agent remains stable even if inputs are incomplete. It ensures the financial logic stays consistent across multiple steps.

Setup guide

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

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

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