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 .

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
