PowerShellのGet-PSDriveコマンドレットを実行してドライブ情報を取得します
AI agents call get_psdrive to retrieve information from Claude MCP Server Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Get-PSDrive is a standard PowerShell diagnostic/query cmdlet that retrieves metadata about mounted drives, partitions, and PowerShell providers. It performs no write, delete, execute, or financial operations—it only queries and returns information. The blast radius of misuse is minimal since the tool cannot modify system state, delete data, or trigger external processes.
From the tool's definition Tool description states it executes PowerShell's Get-PSDrive commandlet to 'retrieve drive information' (ドライブ情報を取得します). Get-PSDrive is a read-only enumeration command that lists available drives and their properties without modifying any data.
