WHAT IT DOES

What list_document_libraries does on Sharepoint

AI agents call list_document_libraries to retrieve information from Sharepoint without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_document_libraries is rated Low

This tool retrieves metadata about document libraries without creating, modifying, or deleting any resources. It is a read-only enumeration operation with minimal blast radius if misused by an AI agent—at worst, it exposes the names and structure of available document libraries but causes no side effects.

From the tool's definition Tool name 'list_document_libraries' and description 'List all document libraries in the SharePoint site' indicate a query/enumeration operation with no modification of data.
