AI agents call nodes_get 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 retrieves information about a specific node using its UUID identifier. It performs a simple query/fetch operation that does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an attacker could read node configuration or status information, but cannot alter system state or cause irreversible damage.
From the tool's definition Tool name 'nodes_get' and description 'Get a specific node by UUID' indicate a retrieval operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access nodes_get 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 nodes_get:
{
"version": "1",
"default": "deny",
"tools": {
"nodes_get": {}
}
}nodes_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a specific node by UUID. 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 nodes_get: 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.
nodes_get 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 nodes_get 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 nodes_get. 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.
nodes_get 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.
