AI agents call list_folder_documents to retrieve information from Mycase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves a list of documents from a folder without modifying, deleting, or executing anything. It is a straightforward read operation that returns information about existing documents. The low severity reflects minimal blast radius—listing documents does not expose sensitive client data differently than other read operations in a law firm system, though the data itself may be sensitive.
From the tool's definition Tool name is 'list_folder_documents' and description states 'List documents inside a specific folder.' The verb 'list' indicates a retrieval operation with no side effects.
