AI agents call dom_read 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.
The tool performs data retrieval from already-located DOM elements. Reading element properties (such as text content, attributes, styles) is a passive operation that does not modify state, execute code, or trigger external effects. It is clearly in the Read category with low severity since it only observes existing data.
From the tool's definition Tool name includes 'read' and description states 'Read a property from a previously found element.' This retrieves element properties without modifying the DOM or triggering side effects.
Attacks that exploit this kind of access
Read a property from 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_read: 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_read 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_read 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_read. 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_read 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.
