AI agents use squads_add_users 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 group membership by adding users to a squad, which is a reversible write operation. It has moderate severity because unauthorized squad membership changes could affect access controls and user permissions within the VPN management system, but the action is not destructive, financial, or code-execution based.
From the tool's definition Tool name 'squads_add_users' and description 'Add users to an internal squad' indicate a create/modify operation that adds users to a group resource.
Documented attack patterns abuse exactly the kind of access squads_add_users 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 squads_add_users:
{
"version": "1",
"default": "deny",
"tools": {
"squads_add_users": {
"limits": [
{
"counter": "squads_add_users_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}squads_add_users 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.
Add users to an internal squad. 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 squads_add_users: 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.
squads_add_users 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 squads_add_users 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 squads_add_users. 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.
squads_add_users 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.
