Legacy: List child nodes
AI agents call listChildren to retrieve information from AEM 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 lists child nodes in AEM's content hierarchy. The verb 'list' and absence of any modification language (create, update, delete, execute) confirm it is a read-only operation. Even on a destructive server context, the tool itself has no side effects—it simply queries and returns data. Severity is low as misuse would only expose information, not cause operational harm.
From the tool's definition Tool name 'listChildren' and description 'Legacy: List child nodes' indicate a query/retrieval operation that enumerates hierarchical data without modification.
Attacks that exploit this kind of access
Legacy: List child nodes. It is categorised as a Read tool in the AEM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AEM MCP Server MCP server in PolicyLayer and add a rule for listChildren: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AEM MCP Server. Nothing to install.
listChildren is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the listChildren rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for listChildren. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
listChildren is provided by the AEM MCP Server MCP server (udaykumarbpatel/aem-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
