Manage and Convert Time Across Timezones

Time MCP Server

A Model Context Protocol server that provides time and timezone conversion capabilities. This server enables LLMs to get current time information and perform timezone conversions using IANA timezone names, with automatic system timezone detection.

Source: https://github.com/modelcontextprotocol/servers/tree/main/src/time

Requires MCP Python SDK 1.x (mcp>=1.29.0,<2). SDK 2.0 renamed APIs this server uses. The port to v2 is in progress.

Available Tools

• get_current_time - Get current time in a specific timezone or system timezone.

  • Required arguments:
    • timezone (string): IANA timezone name (e.g., 'America/New_York', 'Europe/London')

• convert_time - Convert time between timezones.

  • Required arguments:
    • source_timezone (string): Source IANA timezone name
    • time (string): Time in 24-hour format (HH:MM)
    • target_timezone (string): Target IANA timezone name

Installation

Using uv (recommended)

When using uv no specific installation is needed. We will
use uvx to directly run mcp-server-time.

uvx mcp-server-time

Using PIP

Alternatively you can install mcp-server-time via pip:

pip install mcp-server-time

After installation, you can run it as a script using:

python -m mcp_server_time

Configuration

Configure for Claude.app

Add to your Claude settings:

{
  "mcpServers": {
    "time": {
      "command": "uvx",
      "args": ["mcp-server-time"]
    }
  }
}

{
  "mcpServers": {
    "time": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "LOCAL_TIMEZONE", "mcp/time"]
    }
  }
}

{
  "mcpServers": {
    "time": {
      "command": "python",
      "args": ["-m", "mcp_server_time"]
    }
  }
}

Configure for Zed

Add to your Zed settings.json:

"context_servers": [
  "mcp-server-time": {
    "command": "uvx",
    "args": ["mcp-server-time"]
  }
],

"context_servers": {
  "mcp-server-time": {
    "command": "python",
    "args": ["-m", "mcp_server_time"]
  }
},

Configure for VS Code

For quick installation, use one of the one-click install buttons below...

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is needed when using the mcp.json file.

{
  "mcp": {
    "servers": {
      "time": {
        "command": "uvx",
        "args": ["mcp-server-time"]
      }
    }
  }
}

{
  "mcp": {
    "servers": {
      "time": {
        "command": "docker",
        "args": ["run", "-i", "--rm", "mcp/time"]
      }
    }
  }
}

Configure for Zencoder

1. Go to the Zencoder menu (...)
2. From the dropdown menu, select Agent Tools
3. Click on the Add Custom MCP
4. Add the name and server configuration from below, and make sure to hit the Install button

{
    "command": "uvx",
    "args": ["mcp-server-time"]
  }

Customization - System Timezone

By default, the server automatically detects your system's timezone. You can override this by adding the argument --local-timezone to the args list in the configuration.

Example:

{
  "command": "python",
  "args": ["-m", "mcp_server_time", "--local-timezone=America/New_York"]
}

Example Interactions

1. Get current time:

{
  "name": "get_current_time",
  "arguments": {
    "timezone": "Europe/Warsaw"
  }
}

Response:

{
  "timezone": "Europe/Warsaw",
  "datetime": "2024-01-01T13:00:00+01:00",
  "is_dst": false
}

2. Convert time between timezones:

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

Response:

{
  "source": {
    "timezone": "America/New_York",
    "datetime": "2024-01-01T12:30:00-05:00",
    "is_dst": false
  },
  "target": {
    "timezone": "Asia/Tokyo",
    "datetime": "2024-01-01T12:30:00+09:00",
    "is_dst": false
  },
  "time_difference": "+13.0h",
}

Debugging

You can use the MCP inspector to debug the server. For uvx installations:

npx @modelcontextprotocol/inspector uvx mcp-server-time

Or if you've installed the package in a specific directory or are developing on it:

cd path/to/servers/src/time
npx @modelcontextprotocol/inspector uv run mcp-server-time

Examples of Questions for Claude

1. "What time is it now?" (will use system timezone)
2. "What time is it in Tokyo?"
3. "When it's 4 PM in New York, what time is it in London?"
4. "Convert 9:30 AM Tokyo time to New York time"

Build

Docker build:

cd src/time
docker build -t mcp/time .
