Time MCP Server

Overview

Time gives a model two small, deterministic tools: get the current time in any IANA timezone, and convert a time between two timezones, so it stops guessing at timezone math. It's one of the official Model Context Protocol reference servers.

How it works

1. get_current_time takes an IANA timezone name (e.g. America/New_York) and returns the current datetime plus whether daylight saving is active; with no argument it uses the system's own timezone.
2. convert_time takes a source timezone, a 24-hour time, and a target timezone, and returns both datetimes plus the time difference.
3. The system timezone default can be overridden with --local-timezone.

Examples

{
  "name": "convert_time",
  "arguments": {
    "source_timezone": "America/New_York",
    "time": "16:30",
    "target_timezone": "Asia/Tokyo"
  }
}

Installation

You need uv (recommended) or Python with pip.

1. Add the server to your MCP client's config using the block in the sidebar.
2. Restart your client.
3. Optional: pass --local-timezone to override the system's default timezone.
