AI agents use node_plugins_update 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 creates or modifies node plugin settings reversibly. While it doesn't delete data (ruling out Destructive), updating VPN node plugins can significantly impact service availability, performance, and security posture if misconfigured. The high severity reflects the blast radius: misconfiguration could disrupt VPN services or expose traffic.
From the tool's definition Tool name 'node_plugins_update' explicitly indicates modification of node plugin configuration. Description states 'Update a node plugin', confirming it modifies existing data. The VPN context shows this affects infrastructure components that route traffic.
Documented attack patterns abuse exactly the kind of access node_plugins_update 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 node_plugins_update:
{
"version": "1",
"default": "deny",
"tools": {
"node_plugins_update": {
"limits": [
{
"counter": "node_plugins_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}node_plugins_update 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.
Free to start. No card required.
Update a node plugin. 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 node_plugins_update: 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.
node_plugins_update 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 node_plugins_update 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 node_plugins_update. 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.
node_plugins_update 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.
