Time MCP Server

A Model Context Protocol server that provides time-related capabilities. This server enables LLMs to access current time information and convert times between different timezones. This is a Swift implementation of a time MCP server using the MCP Swift SDK.

✨ Features

• Current Time Queries: Get the current time in any timezone
• Time Zone Conversions: Convert time between different timezones
• Daylight Saving Time Information: Check if a timezone is currently in DST
• Time Difference Calculation: Get the time difference between timezones when converting

Available Tools

• get_current_time - Get the current time in a specific timezone

• timezone (string, required): IANA timezone name (e.g., 'America/New_York', 'Europe/London'). If empty or not provided, the system timezone will be used.

• convert_time - Convert time between timezones

• source_timezone (string, required): Source IANA timezone name. If empty or not provided, the system timezone will be used.
• time (string, required): Time to convert in 24-hour format (HH:MM)
• target_timezone (string, required): Target IANA timezone name. If empty or not provided, the system timezone will be used.

Installation

Option 1: One-Line Installation (curl)

The easiest way to install is with the one-line installer, which automatically downloads the latest version and installs it to ~/.local/bin in your home directory:

curl -fsSL https://raw.githubusercontent.com/okooo5km/time-mcp-server/main/install.sh | bash

The installer will:

• Create ~/.local/bin if it doesn't exist
• Add this directory to your PATH (in .zshrc or .bashrc)
• Download and install the latest version
• Make the binary executable

Option 2: Build from Source

1. Clone the repository:

bash git clone https://github.com/okooo5km/time-mcp-server.git cd time-mcp-server

1. Build the project:

bash swift build -c release

1. Install the binary:

bash # Install to user directory (recommended, no sudo required) mkdir -p ~/.local/bin cp $(swift build -c release --show-bin-path)/time-mcp-server ~/.local/bin/

Make sure ~/.local/bin is in your PATH by adding to your shell configuration file:

bash echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc # or ~/.bashrc source ~/.zshrc # or source ~/.bashrc

Command Line Arguments

The server supports the following command line arguments:

• -h, --help: Display help information about the server, its usage, and available options
• -v, --version: Display the version number of the time-mcp-server

Example usage:

# Display help information
time-mcp-server --help

# Display version information
time-mcp-server --version

Configure for Claude.app

Add to your Claude settings:

"mcpServers": {
  "RealTime": {
    "command": "time-mcp-server"
  }
}

Configure for Cursor

Add the following configuration to your Cursor editor's Settings - mcp.json:

{
  "mcpServers": {
    "RealTime": {
      "command": "time-mcp-server"
    }
  }
}

Configure for ChatWise

Add the memory MCP server to your Chatwise Settings - Tools.

Example System Prompt

You can use the following system prompt to help Claude utilize the time-mcp-server effectively:

You have access to time-related tools through MCP. Use these to help users:

- Get the current time in any timezone
- Convert times between timezones
- Calculate time differences between locations
- Plan meetings across different timezones

Use the following tools appropriately:
- `get_current_time` for checking the current time in a specific timezone
- `convert_time` when the user needs to convert between timezones

Always use proper IANA timezone names (e.g., 'America/New_York', 'Europe/London', 'Asia/Tokyo') 
rather than abbreviations or common names.

Development Requirements

• Swift 6.0 or later
• macOS 14.0 or later
• MCP Swift SDK 0.2.0 or later

Usage Examples

Getting Current Time

{
  "timezone": "America/New_York"
}

Response:

{
  "timezone": "America/New_York",
  "datetime": "2024-11-05T14:30:45-05:00",
  "is_dst": false
}

Converting Time

{
  "source_timezone": "America/Los_Angeles",
  "time": "15:30",
  "target_timezone": "Asia/Tokyo"
}

Response:

{
  "source": {
    "timezone": "America/Los_Angeles",
    "datetime": "2024-11-05T15:30:00-08:00",
    "is_dst": false
  },
  "target": {
    "timezone": "Asia/Tokyo",
    "datetime": "2024-11-06T08:30:00+09:00",
    "is_dst": false
  },
  "time_difference": "+17h"
}

Use Cases

• International Meeting Planning: Schedule meetings across different timezones
• Travel Planning: Check local times at destination
• Remote Work Coordination: Coordinate work hours with international teams
• Event Scheduling: Set up global events with correct local times
• Time-Sensitive Operations: Ensure operations happen at the correct local time
