AI agents use nodes_reorder to create or update resources in Remnawave — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Remnawave environment.
This tool modifies the ordering/arrangement of nodes, which is a reversible write operation. It doesn't delete or create nodes, just changes their sequence. Misuse could disrupt VPN node routing or display order but is generally reversible by reordering again.

Documented attack patterns abuse exactly the kind of access nodes_reorder 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_reorder:
{
"version": "1",
"default": "deny",
"tools": {
"nodes_reorder": {
"limits": [
{
"counter": "nodes_reorder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}nodes_reorder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Reorder nodes by providing an ordered array of UUIDs. It is categorised as a Write tool in the Remnawave MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Remnawave MCP server in PolicyLayer and add a rule for nodes_reorder: 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_reorder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the nodes_reorder 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_reorder. 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_reorder 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.
