Why ioc_pack_list needs a policy

This tool queries and enumerates available IoC (Indicator of Compromise) packs and their metadata. It is purely informational—retrieving pack names, license information, and rule counts without creating, modifying, executing, or deleting anything. This is a read-only discovery operation typical of forensic reference data access, with minimal blast radius if misused by an AI agent.

From the tool's definition Tool performs a 'list' operation of IoC packs with metadata retrieval. The word 'list' and the description 'List bundled and optional external behavioral IoC packs, including license metadata and rule counts' indicate a query that retrieves information…

POLICY

How to control ioc_pack_list

PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ioc_pack_list:

policy.json

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

ioc_pack_list 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 Windows Forensics MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about ioc_pack_list

What does the ioc_pack_list tool do? +

List bundled and optional external behavioral IoC packs, including license metadata and rule counts. It is categorised as a Read tool in the Windows Forensics MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on ioc_pack_list? +

Register the Windows Forensics MCP Server MCP server in PolicyLayer and add a rule for ioc_pack_list: 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 Windows Forensics MCP Server. Nothing to install.

What risk level is ioc_pack_list? +

ioc_pack_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit ioc_pack_list? +

Yes. Add a rate_limit block to the ioc_pack_list 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.

How do I block ioc_pack_list completely? +

Set action: deny in the PolicyLayer policy for ioc_pack_list. 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.

What MCP server provides ioc_pack_list? +

ioc_pack_list is provided by the Windows Forensics MCP Server MCP server (x746b/winforensics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Windows Forensics MCP Server tool call.

Start from Windows Forensics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
