List all connected displays with their dimensions and properties.
AI agents call list_displays to retrieve information from Computer Use MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns display metadata (dimensions, properties). It performs no state changes, does not execute arbitrary code, and has no destructive or financial implications. The blast radius of misuse is minimal—an agent might learn about connected displays but cannot cause harm. Classification as Read is appropriate.
From the tool's definition Tool name and description indicate it 'List[s] all connected displays with their dimensions and properties' — a query operation that retrieves system information without modification or side effects.
Attacks that exploit this kind of access
List all connected displays with their dimensions and properties. It is categorised as a Read tool in the Computer Use MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Computer Use MCP Server MCP server in PolicyLayer and add a rule for list_displays: 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 Computer Use MCP Server. Nothing to install.
list_displays 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_displays 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_displays. 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_displays is provided by the Computer Use MCP Server MCP server (syedazharmbnr1/computer-use-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
