AI agents use users_bulk_all_extend_expiration 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 expiration dates for all users in bulk, which is a write operation with high blast radius since it affects every user simultaneously. It is reversible in principle (dates could be changed back), so it falls under Write rather than Destructive, but the mass scope makes it high severity.

Documented attack patterns abuse exactly the kind of access users_bulk_all_extend_expiration 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 users_bulk_all_extend_expiration:
{
"version": "1",
"default": "deny",
"tools": {
"users_bulk_all_extend_expiration": {
"limits": [
{
"counter": "users_bulk_all_extend_expiration_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}users_bulk_all_extend_expiration 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.
Extend expiration date for ALL users. 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 users_bulk_all_extend_expiration: 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.
users_bulk_all_extend_expiration 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 users_bulk_all_extend_expiration 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 users_bulk_all_extend_expiration. 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.
users_bulk_all_extend_expiration 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.
