AI agents call get_firewall_bypass to retrieve information from eToro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation with no stated side effects or modifications. The verb 'Retrieve' and the object 'system bypass rules' clearly indicate it reads and returns existing configuration state rather than creating, modifying, deleting, or executing operations.

From the tool's definition Tool name 'get_firewall_bypass' with action verb 'Retrieve' and description 'Retrieve the system bypass rules' indicates a read-only operation that queries existing firewall bypass configuration data.
