GET /workspaces/{workspaceId}/documents
AI agents call ariba_procure_workspace_list_documents to retrieve information from SAP Ariba MCP Server 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 workspace. It uses the HTTP GET method, which is inherently safe and read-only. There is no capability to modify, delete, create, execute, or charge funds. The blast radius is minimal as it only exposes data the authenticated user already has access to retrieve.
From the tool's definition Tool name contains 'list_documents' and description is 'GET /workspaces/{workspaceId}/documents', indicating a read-only retrieval operation with no mutation or side effects.
