Add business days directly in Cursor

Stop writing custom date-skipping logic for your features. Use `add_business_days` to let your agent calculate deadlines while respecting weekend boundaries. Cursor can inject these results straight into your source code. You get clean, verified dates without the usual headache of manual calculation.

Leap year validation for Cursor agents

Check if a year is a leap year using the `check_leap_year` tool. It provides a definitive true or false response based on standard Gregorian rules. Your Cursor agent uses this to handle leap-day logic in your codebase. It ensures your date-sensitive code remains accurate for years to come.

Calculate date spans within Cursor

Find the exact duration between two dates by calling `calculate_date_difference`. It outputs the precise difference in days, months, and years. Cursor uses this to audit time-based records in your files. You get mathematical accuracy that matches your business requirements perfectly.

Setup guide

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

.cursor/mcp.json

{
  "mcpServers": {
    "deterministic-datetime-engine-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about Deterministic Datetime Engine MCP in Cursor

Create a .cursor/mcp.json file in your project root. Define the server path there, and your agent will pick up the tools automatically in the next chat session.

Yes. Once configured, Cursor agents can call the engine tools to verify dates while writing or refactoring your code.

It is. The engine provides deterministic outputs that don't rely on system clocks, ensuring your code behaves the same way regardless of the environment.

You can commit the .cursor/mcp.json file to your repository. This allows every team member using Cursor to access the same temporal tools.

Your input dates are processed locally as ephemeral parameters. The engine does not store or transmit any of your project's date information to external servers.
