AI agents call list_recent_screenshots to retrieve information from macOS Simulator 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 queries and retrieves metadata about previously captured screenshots. It performs no side effects, does not modify or delete data, and does not execute commands or control system actions. It is a straightforward read operation that provides information about available visual data. The sibling tools (click, diagnostic) perform the actual system interactions; this tool merely inventories the results.
From the tool's definition Tool description states it 'List recently captured and saved screenshots' and 'Returns chronologically sorted list of screenshot files with details like filename, capture time, file size, and dimensions'.
Documented attack patterns abuse exactly the kind of access list_recent_screenshots gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and macOS Simulator MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_recent_screenshots:
{
"version": "1",
"default": "deny",
"tools": {
"list_recent_screenshots": {}
}
}list_recent_screenshots is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List recently captured and saved screenshots with metadata including timestamps, file sizes, and basic information. Essential for accessing previously captured screenshots for comparison, analysis, or review. Returns chronologically sorted list of screenshot files with details like filename, capture time, file size, and dimensions when available. Use this to find specific screenshots by timestamp or to see what visual data is available for analysis. Commonly used before view_screenshot or extract_text_from_screenshot operations. It is categorised as a Read tool in the macOS Simulator MCP Server MCP Server, which means it retrieves data without modifying state.
Register the macOS Simulator MCP Server MCP server in PolicyLayer and add a rule for list_recent_screenshots: 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 macOS Simulator MCP Server. Nothing to install.
list_recent_screenshots 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_recent_screenshots 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_recent_screenshots. 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_recent_screenshots is provided by the macOS Simulator MCP Server MCP server (ohqay/mac-commander). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from macOS Simulator MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
