AI agents call list_files_categories to retrieve information from Wpm 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 simple data retrieval operation without modifying, deleting, or executing any operations. It merely lists available file categories, making it a Read operation with low severity. The sibling tools on this server include financial operations (payments, refunds, auto_payments) and destructive operations (clear_transactions), but this specific tool is limited to retrieval.
From the tool's definition Tool name 'list_files_categories' and description 'Retrieves a list of file categories' indicate a retrieval operation with no side effects. The verb 'Retrieves' and the query-like nature (list operation) are characteristic of Read category tools.
