About Date Utils Engine MCP Server

LLMs suffer from 'calendar blindness'. Because they lack a continuous clock and process dates as text tokens, asking an AI 'What is 45 days from October 12th?' often results in a hallucinated, incorrect date (forgetting November has 30 days, or missing a leap year). This MCP brings the industry standard date-fns and date-fns-tz to your agentic workflows.

LangChain's ecosystem of 500+ components combines seamlessly with Date Utils Engine through native MCP adapters. Connect 4 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

The Superpowers

Flawless Date Math: Safely add or subtract days, months, and years while guaranteeing 100% calendar accuracy.
Timezone Mastery: Convert UTC timestamps into any exact IANA timezone (e.g. America/Sao_Paulo) automatically accounting for Daylight Savings Time shifts without guessing.
Zero Latency: Executes as native V8 javascript local. Does not rely on external calendar APIs.

The Date Utils Engine MCP Server exposes 4 tools through the Vinkius. Connect it to LangChain in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

All 4 Date Utils Engine tools available for LangChain

When LangChain connects to Date Utils Engine through Vinkius, your AI agent gets direct access to every tool listed below — spanning date-math, timezone-conversion, leap-year, and more. Every call runs in a secure, isolated environment with full audit visibility. Beyond a simple connection, you get real-time monitoring of agent activity, enterprise governance, and optimized token usage.

add

Add days on Date Utils Engine

Pass the base ISO date and the number of days (negative to subtract). Receives the exact resulting date. Adds or subtracts a specific number of calendar days from a date deterministically

diff

Diff dates on Date Utils Engine

Pass both ISO date strings and receive the delta in days, hours, minutes, and seconds. Calculates the exact number of calendar days between two dates

parse

Parse date on Date Utils Engine

Pass the raw date string and receive a confirmed valid date object. Parses an ISO date string safely to ensure it is valid

To timezone on Date Utils Engine

Pass the ISO date string and the IANA timezone identifier (e.g. "America/Sao_Paulo", "Europe/London"). Accounts for daylight saving time automatically. Converts a UTC or ISO date string to a specific IANA timezone safely accounting for daylight savings
