GET /costGroupDocuments/{costGroupDocumentId}
AI agents call ariba_cost_breakdown_get_document 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 retrieves cost breakdown/cost group document data from SAP Ariba. It is a read operation with no side effects. Severity is medium rather than low because cost data in procurement systems can be sensitive (pricing, margins, supplier costs) and could inform competitive intelligence or expose financial details if misused; however, the blast radius is limited to information disclosure rather than data…
From the tool's definition GET /costGroupDocuments/{costGroupDocumentId} — the HTTP method is GET and the description indicates retrieval of a cost group document by ID, with no modification or deletion verbs present.
