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.

LlamaIndex agents combine Date Utils Engine tool responses with indexed documents for comprehensive, grounded answers. Connect 4 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

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 LlamaIndex in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
