List all root windows with their associated information. Returns a list of root windows, including their window IDs, window titles, process IDs, and process names.
AI agents call list_root_windows to retrieve information from Wuying AgentBay without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates system window metadata (IDs, titles, process IDs, process names) without modifying state, executing commands, or triggering external operations. It is a passive query/enumeration operation typical of Read category tools. While it exposes system information that could inform reconnaissance, the action itself is non-destructive and read-only.

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

List all root windows with their associated information. Returns a list of root windows, including their window IDs, window titles, process IDs, and process names. It is categorised as a Read tool in the Wuying AgentBay MCP Server, which means it retrieves data without modifying state.
Register the Wuying AgentBay MCP server in PolicyLayer and add a rule for list_root_windows: 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 Wuying AgentBay. Nothing to install.
list_root_windows 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 list_root_windows 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 list_root_windows. 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.
list_root_windows is provided by the Wuying AgentBay MCP server (michael98671/agentbay). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wuying AgentBay, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
