WHAT IT DOES

What list_pages does on Js Reverse

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

RISK

Why list_pages is rated Low

This tool retrieves information about open browser pages without side effects. It is purely informational and does not modify, execute, delete, or move any data. The low severity reflects minimal blast radius — an agent misusing this can only enumerate pages, not interact with or modify them.

From the tool's definition Tool is named 'list_pages' and described as 'Get a list of pages open in the browser' — a direct retrieval operation with no modification or execution capabilities.

RECOMMENDED RULE

list_pages Allowed

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

    "list_pages": {}
  }
}

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