AI agents call list_hooks to retrieve information from JS Reverse Strong MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the state of active hooks in a JavaScript debugging/reverse engineering environment without modifying, executing, or deleting anything. It is purely observational, consistent with the Read category (search, list, get, fetch). The blast radius is minimal—exposure allows an agent to observe what hooks exist, but cannot activate, deactivate, or trigger them.
From the tool's definition Tool name 'list_hooks' and description 'Lists all active function hooks' indicate a retrieval/query operation with no side effects. The verb 'lists' is a canonical Read operation.
Documented attack patterns abuse exactly the kind of access list_hooks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and JS Reverse Strong MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_hooks:
{
"version": "1",
"default": "deny",
"tools": {
"list_hooks": {}
}
}list_hooks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Lists all active function hooks. It is categorised as a Read tool in the JS Reverse Strong MCP MCP Server, which means it retrieves data without modifying state.
Register the JS Reverse Strong MCP server in PolicyLayer and add a rule for list_hooks: 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 JS Reverse Strong MCP. Nothing to install.
list_hooks is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_hooks 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.
Set action: deny in the PolicyLayer policy for list_hooks. 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.
list_hooks is provided by the JS Reverse Strong MCP server (lwjjike/jsreverser-strong-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from JS Reverse Strong MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
