Date Utils Engine

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)

add_days

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_dates

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_date

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

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

FAQ

Frequently asked questions

01

Does it handle Daylight Savings Time?

Yes! Because it leverages date-fns-tz.

02

Can it calculate exact differences?

Yes, it returns the exact calendar days between two dates.

03

Does it support leap years?

Yes, leap years are evaluated natively.

04

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

05

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

06

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

07

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

08

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.

09

Server not appearing after restart

Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).

10

Authentication error

Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.

11

Tools not showing in chat

Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
