AI agents call nodes_tags_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 performs a simple read operation to enumerate node tags from the Remnawave VPN panel. It retrieves information without altering state, executing code, or creating financial obligations. The blast radius of misuse is minimal—an agent could enumerate tags but cannot modify infrastructure or access sensitive user data beyond tag names.
From the tool's definition Tool name 'nodes_tags_list' and description 'List all node tags' indicate a query operation that retrieves existing tag data without modification or side effects.
Documented attack patterns abuse exactly the kind of access nodes_tags_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 nodes_tags_list:
{
"version": "1",
"default": "deny",
"tools": {
"nodes_tags_list": {}
}
}nodes_tags_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all node tags. 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_tags_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.
nodes_tags_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 nodes_tags_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 nodes_tags_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.
nodes_tags_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.
