AI agents call hosts_get to retrieve information from Remnawave without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a specific host using its UUID as a lookup parameter. It performs a read-only query with no side effects, no data modification, and no execution of commands. The operation is informational only, making it a standard Read category tool. Given the VPN panel context, the blast radius of misuse is limited to information disclosure about host configurations.
From the tool's definition Tool description states 'Get a specific host by UUID' - a retrieval operation with no modification or deletion.
Documented attack patterns abuse exactly the kind of access hosts_get 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 hosts_get:
{
"version": "1",
"default": "deny",
"tools": {
"hosts_get": {}
}
}hosts_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a specific host by UUID. It is categorised as a Read tool in the Remnawave MCP Server, which means it retrieves data without modifying state.
Register the Remnawave MCP server in PolicyLayer and add a rule for hosts_get: 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.
hosts_get is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hosts_get 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 hosts_get. 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.
hosts_get 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.
