ai-mcp-demo.py

The provided code demonstrates a simple MCP (Model Context Protocol) server named "host info mcp" built using the `FastMCP` library. It defines a single tool, `get_host_info`, which collects and returns system information—including OS details, memory, CPU count, and CPU model—as a formatted JSON string. The server is configured to run over standard I/O (stdio) and registers the tool for use by an MCP client.
