List all active listeners
AI agents call ligolo_listener_list to retrieve information from Ligolo-ng 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 displays configuration information about active listeners in Ligolo-ng without creating, modifying, deleting, or executing any operations. While Ligolo-ng is used for network pivoting in security assessments, merely listing existing listeners poses minimal risk—it only exposes metadata about the current proxy configuration. The blast radius is limited to information disclosure.
From the tool's definition Tool name and description: 'ligolo_listener_list' - 'List all active listeners'. The verb 'list' and the action of retrieving listener information with no modification capability indicates a read-only query operation.
