AI agents call hwid_devices_list to retrieve information from Remnawave without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of hardware ID devices associated with a user. It performs data retrieval only, with no ability to modify, delete, or execute operations. The blast radius of misuse is limited to information disclosure about the user's registered devices.
From the tool's definition Tool name 'hwid_devices_list' and description 'List HWID devices for a specific user' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access hwid_devices_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Remnawave, and nothing reaches the server without passing your rules. This is the rule we recommend for hwid_devices_list:
{
"version": "1",
"default": "deny",
"tools": {
"hwid_devices_list": {}
}
}hwid_devices_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List HWID devices for a specific user. It is categorised as a Read tool in the Remnawave MCP Server, which means it retrieves data without modifying state.
Register the Remnawave MCP server in PolicyLayer and add a rule for hwid_devices_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 Remnawave. Nothing to install.
hwid_devices_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hwid_devices_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.
Set action: deny in the PolicyLayer policy for hwid_devices_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.
hwid_devices_list is provided by the Remnawave MCP server (trackline/mcp-remnawave). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
