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

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
