WHAT IT DOES

What fw_list_library does on Crow

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

RISK

Why fw_list_library is rated Low

This tool retrieves user identity information for the authenticated session. It is a read-only operation with no capability to modify, delete, or execute actions. The blast radius is minimal as it only exposes user identity data already associated with the current authentication context. Severity is low because this is routine authentication metadata retrieval.

From the tool's definition Tool name 'fw_list_library' with description 'List the authenticated user' indicates a query/retrieval operation that returns information about the current user without modification or side effects.

RECOMMENDED RULE

The rule that runs fw_list_library safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fw_list_library, this is the rule to start with:

fw_list_library Allowed

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

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect Crow, apply this rule, and every fw_list_library call is checked against it from then on.
