Implementation Reference
- src/sysinfo/server.py:114-130 (handler)The main handler function for the 'get_storage_analysis' tool, decorated with @mcp.tool which registers it with the FastMCP server. It adds a header with timestamp, calls the helper get_storage_info() to collect storage data, handles exceptions, and formats the output as a ToolResult using text_response.

Iterates over all disk partitions, calculates capacity and usage statistics, determines disk types, skips temporary filesystems and inaccessible drives, and returns formatted list of storage information.
