MCP server for timezone conversions and time queries with support for IANA timezones

VerifiedSTDIODesktop onlyProductivity & Workflow

Overview

AI-generated overview

A local MCP server that lets an assistant read the current time in any IANA timezone and convert times between timezones.

What you can do
Get the current time in a named IANA timezone or in the detected system timezone, including daylight-saving status and offset details in the response. Convert a given 24-hour time from a source timezone to a target timezone, returning both local datetimes and the time difference.
When to use it
Useful when questions involve the current time somewhere, scheduling across regions, or converting a stated time from one timezone to another. It is a small, single-purpose addition rather than a general utility server.
Requirements
Runs as a local process over stdio. Needs a Python runtime with the package installed via pip, or uv/uvx to run it without a separate install; a Docker image is also documented. No accounts, API keys or headers are declared. The system timezone is detected automatically and can be overridden with a local-timezone argument.
Before you install
Read-only: it only reports and converts times, with no writes, sends or deletions. No credentials are requested. Results depend on the host machine's clock and timezone database, so the detected system timezone may need overriding if it is wrong.

Installation

In SourceWeft

  1. Open Time Mcp Server in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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.

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

Configuration

Configure for Claude.app

Add to your Claude settings:

Using uvx
json
{  "mcpServers": {    "time": {      "command": "uvx",      "args": ["mcp-server-time"]    }  }}
Using docker
json
{  "mcpServers": {    "time": {      "command": "docker",      "args": ["run", "-i", "--rm", "-e", "LOCAL_TIMEZONE", "mcp/time"]    }  }}
Using pip installation
json
{  "mcpServers": {    "time": {      "command": "python",      "args": ["-m", "mcp_server_time"]    }  }}

Configure for Zed

Add to your Zed settings.json:

Using uvx
json
"context_servers": [  "mcp-server-time": {    "command": "uvx",    "args": ["mcp-server-time"]  }],
Using pip installation
json
"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...

[Install with UV in VS Code] [Install with UV in VS Code Insiders]

[Install with Docker in VS Code] [Install with Docker in VS Code Insiders]

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.

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

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}
  1. 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/timenpx @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:

bash
cd src/timedocker build -t mcp/time .
