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.

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.

Using PIP

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

pip install time-mcp-local

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

python -m time-mcp-local

Configuration

Configure for Claude.app

Add to your Claude settings:

<details> <summary>Using uvx</summary>

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

</details>

<details> <summary>Using pip installation</summary>

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

</details>

Configure for Zed

Add to your Zed settings.json:

<details> <summary>Using uvx</summary>

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

</details>

<details> <summary>Using pip installation</summary>

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

</details>

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", "time_mcp_local", "--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 time-mcp-local

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 time-mcp-local

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"
