## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_scripts",
    "arguments": {}
  }
}
```

## Why list_scripts is rated Low

This tool retrieves and queries information about JavaScript scripts in the browser's current page context. It performs no modifications, deletions, code execution, or financial operations. It is purely informational, supporting the debugging and reverse engineering workflow by enumerating available scripts.

From the tool's own definition: "Tool description states it 'Lists all JavaScript scripts loaded in the current page' and returns 'script ID, URL, and source map information'."

## Use case

AI agents call list_scripts 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Js Reverse:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_scripts": {}
  }
}
```
