AI agents use system_generate_x25519 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 and generates new cryptographic keys for VPN configuration. While key generation itself is not inherently destructive, it creates persistent system artifacts (key pairs) that modify the VPN panel state. This is a Write operation because it produces new data that persists in the system.
From the tool's definition Tool name 'system_generate_x25519' and description 'Generate X25519 key pair for VLESS Reality' indicate creation of cryptographic key material that is stored/persisted in the system.

Documented attack patterns abuse exactly the kind of access system_generate_x25519 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 system_generate_x25519:
{
"version": "1",
"default": "deny",
"tools": {
"system_generate_x25519": {
"limits": [
{
"counter": "system_generate_x25519_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}system_generate_x25519 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.

Generate X25519 key pair for VLESS Reality. 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 system_generate_x25519: 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.
system_generate_x25519 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 system_generate_x25519 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 system_generate_x25519. 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.
system_generate_x25519 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.
