Why get_request_initiator needs a policy

This tool passively inspects existing network request metadata and call stack traces for analysis purposes. It performs no mutations, code execution, network operations, or destructive actions. The core function is data retrieval—extracting diagnostic information about what triggered a request.

From the tool's definition Tool name 'get_request_initiator' and description 'Gets the JavaScript call stack that initiated a network request' indicate it retrieves and queries runtime state (call stack information) without modifying or executing code.

POLICY

How to control get_request_initiator

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 get_request_initiator:

policy.json

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

get_request_initiator is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register JS Reverse Strong MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
