Simple Timeserver MCP server for AI agents

This MCP Simple Timeserver helps solve Claude's inability to access time information by providing the current local time and UTC time. It enables Claude to know what time it is at your location and calculate time differences between interactions.

Installation Options

Using Smithery (Automated Installation)

The easiest way to install Simple Timeserver for Claude Desktop is via Smithery:

npx -y @smithery/cli install mcp-simple-timeserver --client claude

Manual Installation

Step 1: Install the Python Package

Install the module using pip:

pip install mcp-simple-timeserver

Step 2: Configure in Claude Desktop App

For macOS:

Add the following to your Claude desktop app configuration:

"mcpServers": {
  "simple-timeserver": {
    "command": "python",
    "args": ["-m", "mcp_simple_timeserver"]
  }
}

For Windows:

First, find your Python executable path by running this in Command Prompt:
```
where python
```

Add the configuration using the correct path:

"mcpServers": {
  "simple-timeserver": {
    "command": "C:\\Users\\YOUR_USERNAME\\AppData\\Local\\Programs\\Python\\Python311\\python.exe",
    "args": ["-m", "mcp_simple_timeserver"]
  }
}

Using a Hosted Version

If you prefer not to install anything locally, you can use the hosted version by adding the following URL to Claude:

https://mcp.andybrandt.net/timeserver

Note that this hosted version only works with Claude, not with ChatGPT, as ChatGPT currently only supports MCP servers that implement search() and fetch() tools.

Available Tools

Once configured, Claude will have access to two time-related tools:

get_local_time: Provides the current local time and timezone information from your machine
get_utc: Provides current UTC time obtained from an NTP time server

Claude can use these tools automatically when needed to reference the current time or calculate time differences.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "simple-timeserver" '{"command":"python","args":["-m","mcp_simple_timeserver"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "simple-timeserver": {
            "command": "python",
            "args": [
                "-m",
                "mcp_simple_timeserver"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
