MOST DANGEROUS TOOLS

High Risk

The most dangerous Computer Use MCP Server tools

Execute · Critical computer_batch This tool allows execution of arbitrary sequences of desktop actions whose effects depend entirely on the arguments provided. Execute · Critical run_shell_command This tool allows unrestricted execution of arbitrary shell commands on a macOS system. Execute · Low wait While this tool has minimal direct impact, it is an Execute category tool because it triggers an external operation (a timed delay) that the AI agent controls via arguments (duration in seconds). Execute · Medium double_click Double-clicking triggers UI interactions at arbitrary screen coordinates, which can activate buttons, open files, launch applications, or trigger other desktop actions beyond mere text selection.

24 of Computer Use MCP Server's 33 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Computer Use MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Computer Use MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "request_access": {
    "limits": [
      {
        "counter": "request_access_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_active_window": {
    "limits": [
      {
        "counter": "get_active_window_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
