What list_files does on MCP File Manager

AI agents call list_files to retrieve information from MCP File Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_files needs a policy

This tool retrieves and displays file metadata within the workspace directory. It performs no creation, modification, deletion, or execution of files—only enumeration. The operation is read-only and carries minimal risk even if invoked by an AI agent, as it cannot alter system state or access resources outside the designated workspace.

From the tool's definition Tool name 'list_files' and description 'List all files in workspace' indicates a query/retrieval operation with no data modification or side effects.
