# Time MCP Server

<!-- mcp-name: io.github.modelcontextprotocol/server-time -->

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

A timezone name, here and in `--local-timezone`, must be an exact IANA key, case included: `Europe/Warsaw` is accepted and `europe/warsaw` is rejected on every platform, including macOS, whose case-insensitive filesystem would otherwise resolve it.

## Installation

### Using uv (recommended)

When using [`uv`](https://docs.astral.sh/uv/) no specific installation is needed. We will
use [`uvx`](https://docs.astral.sh/uv/guides/tools/) to directly run *mcp-server-time*.

```bash
uvx mcp-server-time
```

### Using PIP

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

```bash
pip install mcp-server-time
```

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

```bash
python -m mcp_server_time
```

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.

  }
```

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

## Example Interactions

1. Get current time:
```json
{
  "name": "get_current_time",
  "arguments": {
    "timezone": "Europe/Warsaw"
  }
}
```
Response:
```json
{
  "timezone": "Europe/Warsaw",
  "datetime": "2024-01-01T13:00:00+01:00",
  "is_dst": false
}
```

2. Convert time between timezones:
```json
{
  "name": "convert_time",
  "arguments": {
    "source_timezone": "America/New_York",
    "time": "16:30",
    "target_timezone": "Asia/Tokyo"
  }
}
```
Response:
```json
{
  "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:

```bash
npx @modelcontextprotocol/inspector uvx mcp-server-time
```

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

```bash
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"

## Development

Run the tests from `src/time`. They live in `tests/`: `test_protocol.py` drives
the server through an MCP `ClientSession` in-process, `test_entrypoints.py`
covers `main()`, `python -m mcp_server_time` and the console script, and
`test_server.py` unit-tests the time helpers.

```bash
cd src/time
uv run pytest
```

Coverage is a separate command. It measures line and branch coverage of
`src/mcp_server_time`, prints the missing lines, and writes `coverage.json`
(ignored by git):

```bash
cd src/time
uv run --frozen pytest --cov --cov-report=term-missing --cov-report=json
```

Every file must reach 90% of its lines and 90% of its branches. Code that
cannot be reached is marked `# pragma: no cover  # <reason>`, always with the
reason, rather than lowering the bar.

## Build

Docker build:

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

## Contributing

We encourage contributions to help improve mcp-server-time. Bug reports, ideas for new time-related tools, enhancements to existing functionality, and documentation improvements are all valuable.

Contributions arrive as **issues, not pull requests**: the repository maintainers do the implementation. Open an issue with the [bug report or feature request form](https://github.com/modelcontextprotocol/servers/issues/new/choose), and if you have already prototyped a change, share the prompt you used rather than a diff.
