Inspects element visibility, position, and attributes. Use selector OR xpath.
AI agents call dom_inspect_element to retrieve information from Browser-Debugger without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about DOM elements (visibility, position, attributes) without creating, modifying, deleting, or executing any operations. It is a pure read operation similar to querying page state for debugging purposes. The low severity reflects minimal security risk—inspection of rendered page structure poses no direct harm to data, systems, or user assets.
From the tool's definition Tool name 'dom_inspect_element' and description 'Inspects element visibility, position, and attributes' indicate retrieval of DOM metadata without modification. The action is passive inspection/querying of page structure.

PolicyLayer is an MCP gateway — it sits between your AI agents and Browser-Debugger, and nothing reaches the server without passing your rules. This is the rule we recommend for dom_inspect_element:
{
"version": "1",
"default": "deny",
"tools": {
"dom_inspect_element": {}
}
}dom_inspect_element is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Inspects element visibility, position, and attributes. Use selector OR xpath. It is categorised as a Read tool in the Browser-Debugger MCP Server, which means it retrieves data without modifying state.
Register the Browser-Debugger MCP server in PolicyLayer and add a rule for dom_inspect_element: 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 Browser-Debugger. Nothing to install.
dom_inspect_element 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_inspect_element 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_inspect_element. 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_inspect_element is provided by the Browser-Debugger MCP server (selvadinesh-giga/mcp-based-browser-debug-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Browser-Debugger, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
