ファイルタイプ別の統計情報を表示します
AI agents call show_file_type_stats 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.
This tool retrieves and displays aggregate statistics about file types in a filesystem or project. It performs no side effects, creates no resources, executes no code, and modifies no data. It is a straightforward read operation that queries file type information and presents it to the user. The low severity reflects minimal risk even if misused by an AI agent, as it can only expose information that already exists.
From the tool's definition Tool name 'show_file_type_stats' and description 'ファイルタイプ別の統計情報を表示します' (displays statistics by file type) indicates data retrieval and analysis only.
