Get HTTPS listener details
AI agents call get_listener_https to retrieve information from Cobalt Strike MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
While this tool only retrieves information (Read category), the severity is elevated to 'high' because the Cobalt Strike MCP server itself is a red team attack platform. Unauthorized access to listener details could reveal active command & control infrastructure, assist in pivoting attacks, or expose operational security details.
