Real-time milestone tracking

Visualize your path to financial independence by streaming raw data into your interface. Your AI client pulls the numbers from `calculate_milestones` to show users exactly when they hit their target. Stop waiting for loading spinners. By piping this MCP directly into your frontend, users see their retirement timeline shift the moment they adjust their inputs.

Dynamic lifestyle modeling

Define what retirement looks like for your users by integrating `get_lifestyle_targets`. This tool calculates the capital required based on specific annual spending goals. Your application logic can now react instantly to these outputs. It's about moving from static financial charts to interactive, data-backed retirement planning.

Instant contribution feedback

Show the immediate effect of saving more today using `simulate_contribution_impact`. Your AI client processes these simulations to provide instant feedback within the user's dashboard. This creates a tighter feedback loop for your users. They see the math change in real-time, making the long-term goal feel tangible and achievable.

Setup guide

Set up FIRE Calculator MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all FIRE Calculator tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent FIRE Calculator transactions",
});

console.log(text);
await mcpClient.close();

Common questions about FIRE Calculator MCP in Vercel AI SDK

Install the MCP packages and initialize the client using the HTTP transport. You then pass the tools directly into your generation functions to start pulling data.

Yes. Because the SDK supports streaming, you can pipe tool outputs directly into your components as the data arrives. This eliminates the need for manual state updates.

The MCP acts as a bridge for your specific financial inputs. Your data stays within your controlled environment and is only processed by the tools you explicitly invoke.

You need an accessible endpoint for the MCP. Once that is live, your client connects over HTTP to fetch the financial data you need.

The underlying math accounts for inflation adjustments within the milestone calculations. You simply pass the inflation rate as a parameter to the tool.
