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 Vercel AI SDK?
The Vercel AI SDK gives every Date Utils Engine tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 4 tools through Vinkius and stream results progressively to React, Svelte, or Vue components. works on Edge Functions, Cloudflare Workers, and any Node.js runtime.

Frequently asked questions
Does it handle Daylight Savings Time?
Yes! Because it leverages date-fns-tz.
Can it calculate exact differences?
Yes, it returns the exact calendar days between two dates.
Does it support leap years?
Yes, leap years are evaluated natively.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
