Get the list of groups
AI agents call get-group-list to retrieve information from TgeBrowser 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 queries existing group data without creating, modifying, deleting, or executing any operations. It has minimal blast radius even if misused by an AI agent, as it only exposes read-only metadata about groups in the browser automation system.
From the tool's definition Tool name is 'get-group-list' and description states 'Get the list of groups' — a pure retrieval operation with no modification or side effects.
