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

About Installation

If you need to install the package directly (e.g., for development or source code inspection), you can use one of these methods:

• Install from PyPI

  pip install mcp-datetime

• Install from GitHub Source

  git clone https://github.com/ZeparHyfar/mcp-datetime.git
  cd mcp-datetime
  pip install -e .

• Example claude_desktop_config.json for manual installation

  {
    "mcpServers": {
      "mcp-datetime": {
        "command": "python",
        "args": ["-m", "mcp_datetime"],
        "env": {
          "PYTHON": "/path/to/your/python"
        }
      }
    }
  }

  Replace “/path/to/your/python” with your actual Python interpreter path

  e.g., “/usr/local/bin/python3” or “/Users/username/.pyenv/versions/3.12.0/bin/python3”

Debugging

Since MCP servers run over stdio, debugging can be challenging. We recommend using the MCP Inspector :

• Using PyPI package

  npx @modelcontextprotocol/inspector uvx mcp-datetime

• Using downloaded source code from GitHub

  git clone https://github.com/ZeparHyfar/mcp-datetime.git
  npx @modelcontextprotocol/inspector uvx --directory ./mcp-datetime run mcp-datetime
