Share exact math tools across your engineering team

The `calculate_percentage` tool provides a unified way for your team to calculate ratios and percentage splits inside VS Code Copilot. By committing the MCP config to your repository, every developer gets access to the same local math tools. This prevents different team members from getting conflicting calculations from their agents. The tool runs locally on each machine, returning identical, deterministic results across the entire workspace.

Resolve proportionality rules in your workspace

The `calculate_rule_of_three` tool allows your agent to solve proportional scaling equations directly inside your editor. VS Code Copilot uses this tool when refactoring layout engines, calculating aspect ratios, or managing database scaling factors. This local MCP integration ensures your calculations are always accurate. It cuts out the latency of external web searches, delivering precise numbers to your terminal or active file in milliseconds.

Run fast exponents and square roots locally

The `calculate_power` and `calculate_square_root` tools handle complex algebraic operations directly within your editing environment. Your agent uses these tools to generate accurate algorithm mockups and configuration constants. Because the math is executed locally, your developer environment remains secure and offline-capable. You do not have to worry about network latency or rate limits when running heavy calculations.

Setup guide

Set up Fundamental Math MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Fundamental Math MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Fundamental Math tools listed. Try asking: "List my recent Fundamental Math transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

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

Common questions about Fundamental Math MCP in VS Code Copilot

Yes. You can commit the configuration file directly to your repository at `.vscode/mcp.json`. This ensures that every developer on your team has immediate access to the local MCP Server.

Language models are notoriously bad at basic arithmetic. Using this MCP Server ensures that your team's agent uses real mathematical functions rather than guessing numbers.

Yes, completely. Every calculation runs locally as a subprocess on your machine, meaning you can compute percentages and square roots without any internet connection.

You need VS Code version 1.96 or higher to support custom configurations. Once updated, you can run all five math tools directly inside your chat panel.

The server runs as a local process, meaning your raw numbers and equations are executed directly in your system's memory. No calculation inputs or math outputs are ever transmitted over the network or exposed to external APIs.
