SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively.
