GET /groups
AI agents call ariba_approval_list_groups 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 is a simple read operation that retrieves a list of approval groups from SAP Ariba. It has no side effects, does not execute code, does not modify data, and does not involve financial transactions. The use of GET HTTP method and 'list' terminology confirms retrieval-only semantics. Risk is low because viewing group information does not enable destructive or financial actions on its own.
From the tool's definition Tool name contains 'list' and description explicitly states 'GET /groups', indicating a read-only query operation that retrieves group data without modifying state.
