Get a company gateway by ID. GET /gateways/{gatewayId}.
AI agents call get_gateway 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 is a read-only operation that retrieves gateway configuration details by ID. It has no side effects and does not modify, delete, or execute operations. Even in a financial/billing context, a simple GET retrieval of gateway metadata poses minimal risk. The low severity reflects that gateway IDs are typically non-sensitive identifiers and the operation merely fetches existing configuration data.
From the tool's definition Tool name 'get_gateway' with description 'Get a company gateway by ID. GET /gateways/{gatewayId}' indicates a retrieval operation using HTTP GET method.
