Obsidianボルト内のファイルとディレクトリを検索します
AI agents call search_files to retrieve information from Obsidian MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation within an Obsidian vault. It retrieves information about files and directories without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an agent could discover sensitive notes within the vault but cannot alter them. This is a classic Read category tool.
From the tool's definition Tool description states 'search files and directories' (translated from Japanese: 'Obsidianボルト内のファイルとディレクトリを検索します'). The verb 'search' indicates querying/retrieval with no modification or side effects.
