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
