WHAT IT DOES

What capture_screen does on Iconnect

AI agents call capture_screen to retrieve information from Iconnect without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why capture_screen is rated Low

This tool reads/captures visual data from the screen and returns it as an image. It has no write or destructive side effects. However, it can expose sensitive information visible on screen (passwords, private data, confidential documents), making it a medium severity Read operation.

RECOMMENDED RULE

The rule that runs capture_screen safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Iconnect, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capture_screen, this is the rule to start with:

capture_screen Allowed

capture_screen is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "capture_screen": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Iconnect, apply this rule, and every capture_screen call is checked against it from then on.
