AI agents call navigate_dom_path to retrieve information from ZMCPTools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads/queries specific elements within a DOM JSON structure using path notation. It retrieves data without modifying anything. The description indicates a read-only navigation/query operation on an existing DOM representation.

Documented attack patterns abuse exactly the kind of access navigate_dom_path gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ZMCPTools, and nothing reaches the server without passing your rules. This is the rule we recommend for navigate_dom_path:
{
"version": "1",
"default": "deny",
"tools": {
"navigate_dom_path": {}
}
}navigate_dom_path is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the ZMCPTools MCP server in PolicyLayer and add a rule for navigate_dom_path: 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 ZMCPTools. Nothing to install.
navigate_dom_path 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 navigate_dom_path 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 navigate_dom_path. 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.
navigate_dom_path is provided by the ZMCPTools MCP server (zachhandley/zmcptools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
