AI agents call dom_query_in to retrieve information from Ruyipage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the DOM to locate child elements. It is a read-only operation that retrieves data (element references) for subsequent use in browser automation. No data is modified, deleted, or state-changing operations are performed.
From the tool's definition Tool name 'dom_query_in' and description 'Find a child element inside a previously found element' indicate DOM traversal/querying operations that retrieve element references without modifying the DOM or triggering side effects.
Attacks that exploit this kind of access
Find a child element inside a previously found element. It is categorised as a Read tool in the Ruyipage MCP Server, which means it retrieves data without modifying state.
Register the Ruyipage MCP server in PolicyLayer and add a rule for dom_query_in: 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 Ruyipage. Nothing to install.
dom_query_in 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 dom_query_in 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 dom_query_in. 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.
dom_query_in is provided by the Ruyipage MCP server (neverl805/ruyipage_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
