Simple Timeserver MCP server

This is a small helper that gives your AI a sense of time. Normally, your AI has no idea what time or day it is, which makes it awkward when you ask things like what's the date today. This server fixes that, and it can also look up holidays and count days between dates.

What this MCP server does

You ask your AI something like what time is it in Tokyo, or how many days until December 31. Your AI passes the question to this helper. The helper checks the time from a time server on the internet (or your own computer's clock for local time) and looks up holidays from public holiday databases. Then it sends the answer back, and your AI tells it to you in plain words in the chat.

What you can do with it

• Ask what time it is right now, anywhere in the world
• Count the days between two dates, like a countdown to a deadline
• Check whether a specific date is a public holiday in a country
• List all public holidays for a country in a given year
• See school holiday periods for a region or city
• Convert the current time into other calendars like Japanese or Hebrew
• Count only business days between two dates, skipping weekends and holidays

Try asking your AI

• “What time is it in Warsaw right now?”
• “How many days until December 31?”
• “Is January 1st a public holiday in Germany?”
• “List the public holidays in Japan for 2026”

What it gives back to you

You get a short, plain answer in the chat. For time questions, it tells you the time, the day of the week, and the timezone. For holiday questions, it gives you a list or a simple yes or no. For countdowns, it gives you a number, like 42 days or 6 weeks.
