What is the 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.
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.
Built-in capabilities (4)
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
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
Pass the raw date string and receive a confirmed valid date object. Parses an ISO date string safely to ensure it is valid
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
Why Claude Code?
Claude Code registers Date Utils Engine as an MCP server in a single terminal command. Once connected, Claude Code discovers all 4 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where Date Utils Engine data drives decisions without human intervention.
