Search for files and folders using Everything search engine
AI agents call everything_search to retrieve information from Enhanced Everything 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 file system searches, which is a read-only operation. It queries the Everything search index to locate files and folders but has no side effects—it cannot modify, delete, or execute code. The blast radius of misuse is minimal (potential information disclosure of file paths), justifying a 'low' severity rating.
From the tool's definition Tool name 'everything_search' and description 'Search for files and folders using Everything search engine' indicates a query operation that retrieves data without modifying, creating, or deleting resources.
