What run does on MCP Windows Desktop Automation

AI agents invoke run to trigger actions in MCP Windows Desktop Automation. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

Why run needs a policy

This tool can execute arbitrary AutoIt scripts or Windows desktop operations through the MCP protocol. An AI agent could use it to run malicious code, manipulate windows, steal data, or perform unauthorized actions. The blast radius is critical because AutoIt has broad system access and the tool description being empty increases uncertainty, but the server purpose makes execution capability clear.

From the tool's definition Tool named 'run' on a server that 'wraps AutoIt functionality, enabling LLMs to automate Windows desktop tasks including mouse/keyboard operations, window management, and UI control interactions.' The tool description is empty, but the server context and…

Documented attack patterns abuse exactly the kind of access run gives an agent:

How to control run

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Windows Desktop Automation, and nothing reaches the server without passing your rules. This is the rule we recommend for run:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "run": {
      "limits": [
        {
          "counter": "run_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

run stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register MCP Windows Desktop Automation — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on run? +

Register the MCP Windows Desktop Automation MCP server in PolicyLayer and add a rule for run: 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 MCP Windows Desktop Automation. Nothing to install.

What risk level is run? +

run is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run? +

Yes. Add a rate_limit block to the run 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.

How do I block run completely? +

Set action: deny in the PolicyLayer policy for run. 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.

What MCP server provides run? +

run is provided by the MCP Windows Desktop Automation MCP server (mario-andreschak/mcp-windows-desktop-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
