How to Use the Unit & FX Calculator MCP in Cursor

Q: Do I need to set up the Unit & FX Calculator for Cursor?

You add it by creating a .cursor/mcp.json file in your project root, listing the server details under mcpServers. Then, just enable Agent mode when you chat.

Q: Can I use Unit & FX Calculator to check multiple values at once with Cursor?

Yes, definitely. Use batchconvert to pass a list of values and their corresponding units for one deterministic conversion operation.

Inject Live Conversions into Generated Code

When you're coding, the `convert_unit` tool lets your AI agent call math functions to perform deterministic physical unit conversions. You get real API responses—not stubs—that live directly in the code Cursor is generating for you. If you need a value converted from miles per hour to kilometers per hour mid-function, the agent handles it and injects the correct calculation.

Calculate Rates During Agent Mode Coding

Need to write code that uses current financial data? The `get_rate` tool pulls live exchange rates into your project context. This prevents you from hardcoding stale or inaccurate currency values. Your agent can call this MCP Server and use the exact rate in a transaction calculation, making your code immediately functional.

Run Deterministic Batch Conversions

The `batch_convert` tool lets you handle multiple unit conversions at once while writing. You pass an array of values and their units; the agent executes this in a single deterministic pass. This is crucial for data processing scripts where you need to ensure every single metric conversion is mathematically sound.

Setup guide

Set up Unit & FX 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 Unit & FX 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 Unit & FX Calculator transactions." If the MCP tools are loaded correctly, Cursor will call the Unit & FX Calculator tools automatically. You can also check Settings → MCP for a green status indicator.

Common questions about Unit & FX Calculator MCP in Cursor

The tool lets your AI agent call the MCP Server while you're writing code. It injects live, accurate data—like converted units or currency rates—directly into the code block being generated.

You can convert standard physical units (C to F, etc.) using `convert_unit`, handle bulk conversions via `batch_convert`, and fetch current currency exchange rates using `get_rate`.

You add it by creating a `.cursor/mcp.json` file in your project root, listing the server details under `mcpServers`. Then, just enable Agent mode when you chat.

Yes, definitely. Use `batch_convert` to pass a list of values and their corresponding units for one deterministic conversion operation.

This MCP Server handles numerical measurements (values and units) and currency codes. It doesn't access or manipulate any personal user files or identities.
