THE RISK

Low Risk

Why process_list needs a policy

This tool retrieves process information from a remote system via DMA without altering any state. Although the broader server context involves DMA access (which carries elevated risk), process_list itself performs only enumeration. The severity is low because listing processes is informational; misuse reveals running software but does not execute code, modify memory, or delete data.

From the tool's definition Tool description states 'List all running processes on the TARGET system' — a query operation with no modification or side effects. The name 'process_list' and verb 'List' confirm retrieval-only intent.

POLICY

How to control process_list

PolicyLayer is an MCP gateway — it sits between your AI agents and Nevercheese Pcileech Memprocfs, and nothing reaches the server without passing your rules. This is the rule we recommend for process_list:

policy.json

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

process_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 Nevercheese Pcileech Memprocfs — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about process_list

What does the process_list tool do? +

List all running processes on the TARGET system (the machine connected via DMA, not the local machine). It is categorised as a Read tool in the Nevercheese Pcileech Memprocfs MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on process_list? +

Register the Nevercheese Pcileech Memprocfs MCP server in PolicyLayer and add a rule for process_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 Nevercheese Pcileech Memprocfs. Nothing to install.

What risk level is process_list? +

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

Can I rate-limit process_list? +

Yes. Add a rate_limit block to the process_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 process_list completely? +

Set action: deny in the PolicyLayer policy for process_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 process_list? +

process_list is provided by the Nevercheese Pcileech Memprocfs MCP server (neverdecel/nevercheese-pcileech-memprocfs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Nevercheese Pcileech Memprocfs tool call.

Start from Nevercheese Pcileech Memprocfs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
