mcp-simple-timeserver 1.2.0

A simple MCP server that provides current time - either local or from an NTP server.

MCP Simple Timeserver

One of the strange design decisions Anthropic made was depriving Claude of timestamps for messages sent by the user in claude.ai or current time in general. Poor Claude can't tell what time it is! mcp-simple-timeserver is a simple MCP server that fixes that.

Available Tools

This server provides the following tools:

Tool	Description
get_local_time	Returns the current local time, day of week, and timezone from the user's machine
get_utc	Returns accurate UTC time from an NTP time server
get_iso_week_date	Returns the current date in ISO 8601 week date format (e.g., 2026-W03-4)
get_unix_timestamp	Returns the current Unix/POSIX timestamp
get_hijri_date	Returns the current date and time in the Islamic (Hijri) lunar calendar
get_japanese_era_date	Returns the current date and time in the Japanese Era (Nengo) calendar. Supports English and Kanji output via language parameter ("en" or "ja")
get_hebrew_date	Returns the current date and time in the Hebrew (Jewish) calendar, including holiday information. Supports English and Hebrew output via language parameter ("en" or "he")
get_persian_date	Returns the current date and time in the Persian (Jalali/Shamsi) calendar. Supports English and Farsi output via language parameter ("en" or "fa")

All tools (except get_local_time) use accurate time from NTP servers. If NTP is unavailable, they gracefully fall back to local server time with a notice.

Installation

Installing via Smithery

To install Simple Timeserver for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install mcp-simple-timeserver --client claude

Manual Installation

First install the module using:

pip install mcp-simple-timeserver

Then configure in MCP client - the Claude desktop app.

Under Mac OS this will look like this:

"mcpServers": {
  "simple-timeserver": {
    "command": "python",
    "args": ["-m", "mcp_simple_timeserver"]
  }
}

Under Windows you have to check the path to your Python executable using where python in the cmd (Windows command line).

Typical configuration would look like this:

"mcpServers": {
  "simple-timeserver": {
    "command": "C:\\Users\\YOUR_USERNAME\\AppData\\Local\\Programs\\Python\\Python311\\python.exe",
    "args": ["-m", "mcp_simple_timeserver"]
  }
}

Web Server Variant

This project also includes a network-hostable version that can be deployed as a standalone web server. For instructions on how to run and deploy it, please see the Web Server Deployment Guide.

Or you can simply use my server by adding it under https://mcp.andybrandt.net/timeserver to Claude. (It does not work with ChatGPT since it currently works only with MCP servers that implement search() and fetch() tools to serve data in response to LLM's querries).
