Inject real retirement math

This MCP feeds actual financial independence projections into your codebase. When you need to establish a baseline withdrawal strategy, your agent executes `get_lifestyle_targets` to pull the exact capital requirements. You skip writing standard four percent rule logic from scratch. The agent drops the calculated targets directly into your state management.

Map timelines directly in Cursor

Building a dashboard requires accurate compounding projections. Triggering `calculate_milestones` generates the exact dates and portfolio values for different financial independence stages. Your AI client writes the UI components and populates them with these real projections. You test your frontend against actual mathematical models instead of mock data.

Model savings variations

Users need to see how changing their monthly deposits affects their exit date. The `simulate_contribution_impact` operation in this MCP provides those alternative timelines instantly. You tell the agent to build a slider component and it wires up the simulation logic automatically. The math works on the first try.

Setup guide

Set up FIRE Calculator MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the FIRE Calculator MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent FIRE Calculator transactions." If the MCP tools are loaded correctly, Cursor will call the FIRE Calculator tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about FIRE Calculator MCP in Cursor

Create an mcp.json file in your project root. Add the Vinkius MCP connection details and enable Agent mode in your chat panel.

Your agent writes the React or Vue components while pulling the actual financial logic from the tools. You get working code that already handles the math.

Save the configuration in your global settings folder if you want it everywhere. Otherwise keep it scoped to specific financial apps.

Ask your agent to rerun the simulation with a different inflation rate or market return. It updates the injected data and rewrites the affected functions.

The portfolio balances and withdrawal rates you test pass through memory during the session. The MCP calculates the projections without logging your proprietary project details.
