AI agents use squads_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 modifies squad data within the Remnawave VPN panel system. As an update operation, it is reversible and represents a Write-category action. Severity is medium because unauthorized squad modifications could affect access control, user grouping, or operational workflows in a VPN administration context, but the impact is typically scoped to squad configuration rather than system-wide destruction or financial…
From the tool's definition Tool name 'squads_update' and description 'Update an internal squad' indicate modification of existing data. The verb 'Update' is a reversible write operation that creates or modifies data without deletion or financial impact.
Documented attack patterns abuse exactly the kind of access squads_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 squads_update:
{
"version": "1",
"default": "deny",
"tools": {
"squads_update": {
"limits": [
{
"counter": "squads_update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}squads_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.

Update 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_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.
squads_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 squads_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 squads_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.
squads_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.
