WHAT IT DOES

What get_invoice does on Linode MCP Server

RISK

Why get_invoice is rated Low

This tool queries financial/billing data but does not modify, delete, or execute transactions. It is a read operation on sensitive financial records. While it accesses financial information (justifying medium severity due to sensitive data exposure), it does not move money or create financial obligations, so it does not qualify as Financial category.

From the tool's definition Tool name is 'get_invoice' and description states it retrieves 'a specific invoice', indicating data retrieval without modification.
