How to Use the Financial Math Engine MCP in VS Code Copilot

Q: How do we share the Financial Math Engine across our team in VS Code Copilot?

You can commit a .vscode/mcp.json file containing the server configuration directly to your Git repository. Every developer using VS Code Copilot on your team will automatically gain access to the financial math tools.

Q: Can VS Code Copilot generate both SAC and PRICE tables using the Financial Math Engine?

Yes, the calculateamortization tool supports both systems. Your VS Code Copilot agent can generate either schedule and output the raw JSON to help you build automated integration tests.

Q: What level of precision does the compound interest tool provide?

The calculatecompoundinterest tool uses high-precision floating-point math to prevent rounding errors. This ensures that even multi-decade projections remain accurate to the cent.

Equip your VS Code Copilot engineering team with precise financial math tools for amortization and compound interest.

Validate Amortization Logic Team-Wide

The `calculate_amortization` tool gives your VS Code Copilot agent immediate access to standard SAC and PRICE schedule calculations. By sharing this tool configuration via `.vscode/mcp.json` across your team's workspace, every developer can instantly check their code against verified financial algorithms. This prevents developers from committing broken loan math to the repository. The agent runs the amortization engine to verify that your APIs are returning correct principal-to-interest ratios.

Verify Interest Projections in Copilot Chat

The `calculate_compound_interest` tool computes exact future values and interest accumulation over arbitrary timeframes. Your engineering team can use Copilot Chat to run quick scenarios, ensuring that your financial microservices are calculating compound growth correctly. This saves hours of manual verification. Copilot calls the tool, receives the precise decimal outputs, and helps you write tests that assert those exact values.

Standardize Team Workflows with this MCP Server

This MCP Server can be configured at the repository level using VS Code's shared configuration files. Your entire team gets instant access to `calculate_amortization` and `calculate_compound_interest` without individual setup friction. This shared environment ensures that everyone on the project is testing against the exact same mathematical models, reducing compliance risks and alignment issues across your codebase.

Setup guide

Set up Financial Math Engine 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 Financial Math Engine 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 Financial Math Engine tools listed. Try asking: "List my recent Financial Math Engine transactions" and Copilot will invoke them automatically.

.vscode/mcp.json
