What list_hooks does on Js Reverse
AI agents call list_hooks 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.
Why list_hooks is rated Low
This tool retrieves information about active hooks in the browser debugging context. It performs a read-only query that neither modifies state, executes arbitrary code, deletes data, nor affects financial systems. The listing operation is passive inspection of existing hooks without causing any changes or side effects.
From the tool's definition Tool name is 'list_hooks' and description states it 'Lists all active function hooks' — a retrieval/query operation with no side effects.
Attacks that exploit this kind of access
The rule that runs list_hooks safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Js Reverse, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_hooks, this is the rule to start with:
list_hooks is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Js Reverse, apply this rule, and every list_hooks call is checked against it from then on.
