List invoices for a subscription. GET /subscriptions/{subscriptionId}/invoices. Returns paginated invoices. Use include for line-item detail and transactions (e.g. include=detail,transactions).
AI agents call get_subscription_invoices to retrieve information from Rebillia 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 and queries existing invoice data using a GET HTTP method. It does not create, modify, delete, or execute operations. The optional 'include' parameter for additional detail and transactions only affects what data is returned, not the state of the system. This is a standard read operation with no blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_subscription_invoices' and description 'List invoices for a subscription. GET /subscriptions/{subscriptionId}/invoices. Returns paginated invoices.' indicate a retrieval operation with no side effects.
