Get comments from TabNews by content.
AI agents call getContentChildrenTool to retrieve information from MCP TabNews Integration without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It has no side effects and presents minimal risk if misused by an AI agent—the worst outcome would be unauthorized read access to comments, which is a low-severity information disclosure concern.
