How to Use the Fundamental Math MCP in Cursor

Q: How do I configure Fundamental Math in Cursor?

Add the server configuration to your global /.cursor/mcp.json file or your project-specific settings. This registers the MCP Server directly, allowing Agent mode in the chat panel to access the math tools.

Give Cursor the tools to write code with exact, deterministic math. No more broken constants or bad ratios in your files.

Inject exact math constants into your code

The `calculate_power` tool lets your agent compute exact exponents and inject them directly into your active files. Instead of guessing values or writing throwaway scripts, Cursor queries this local MCP tool to write accurate config files. The agent calls the tool in the background while you write code. You get raw, verified numbers pasted directly into your editor without manual math or context switching.

Automate ratio scaling in your codebases

The `calculate_rule_of_three` tool calculates proportional scaling rules for responsive layouts and grid systems. Cursor uses this tool to determine exact pixel or rem values when you ask it to refactor a CSS grid or UI component. This local execution ensures your layouts are mathematically sound before you hit save. There is no guesswork, just fast, accurate ratios generated instantly by your editor.

Calculate factorials and roots instantly

The `calculate_factorial` and `calculate_square_root` tools provide instant mathematical verification during testing and algorithm design. Cursor calls these tools to generate test cases with exact expected outputs. Running this math locally via our MCP Server means your AI client does not have to guess complex sequences. It gets the precise values in milliseconds, keeping your development loop tight.

Setup guide

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

.cursor/mcp.json

  "mcpServers": {
    "fundamental-math-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Common questions about Fundamental Math MCP in Cursor

Add the server configuration to your global `~/.cursor/mcp.json` file or your project-specific settings. This registers the MCP Server directly, allowing Agent mode in the chat panel to access the math tools.

Not at all. Because this MCP Server runs locally on your machine, tool execution takes less than five milliseconds, which is significantly faster than waiting for a cloud API.

Yes. The editor uses these tools to generate exact mathematical assertions. This prevents the agent from writing tests with hallucinated or incorrect numerical outcomes.

If you pass an input larger than 170, the system returns infinity due to standard floating-point limits. The tool handles this safely without crashing your editor session.

Your numeric inputs and calculated results are processed in-memory on your local machine. No mathematical data or parameters are ever logged, cached, or transmitted to any cloud servers.
