Built-in capabilities (3)
Tools for your AI Agents to operate datetime-ops
Ask your AI agent "Calculate the deadline: Add 15 business days to 2024-10-01." and get the answer without opening a single dashboard. With 3 tools connected to real datetime-ops data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by Vinkius — your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

Add business days on Deterministic Datetime Engine
Adds or subtracts a specific number of business days (skipping weekends) from a given date
Calculate date difference on Deterministic Datetime Engine
Calculates the exact mathematical difference between two dates in days, months, and years
Check leap year on Deterministic Datetime Engine
Checks if a specific year is a leap year using the exact Gregorian calendar algorithm
What the Deterministic Datetime Engine MCP Server unlocks
Language Models are infamously bad at calendar math. If you ask an AI to "Add 45 business days to October 12th", it will almost always guess wrong because it cannot programmatically skip weekends and account for varying month lengths. The Datetime Operations MCP solves this by offloading temporal calculations to a strict V8 Javascript engine.
The Superpowers
- Business Day Math: Add or subtract days while perfectly skipping Saturdays and Sundays. Essential for SLA calculations, billing cycles, or delivery estimates.
- Exact Date Differences: Need to know exactly how many days, months, or years passed between two dates? Stop guessing and get mathematically perfect totals instantly.
- Leap Year Logic: Flawlessly implements the Gregorian leap year algorithm (
% 4 == 0 && % 100 !== 0). - Privacy First (Local): Executes completely locally. Zero API latency.
Frequently asked questions about the Deterministic Datetime Engine MCP Server
Why use an MCP for adding days to a date?
AI models predict tokens, they don't "compute" calendars. When crossing months (e.g., February 28th to March 1st) or calculating Business Days, LLMs hallucinate dates frequently. This MCP forces exact algorithmic execution.
Are public holidays supported?
Currently, add_business_days only skips weekends (Saturdays and Sundays). True holiday calculation requires country-specific data which violates the zero-dependency nature of this core utility.
Is this tool secure and local?
Yes. It executes 100% locally using standard Date parsing built into V8. No cloud dependencies or API calls are used.
