AI agents call billing_providers_list 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 performs a simple data retrieval operation to enumerate billing providers. It has no side effects, does not create, modify, or delete data, does not execute external operations, and does not move money. The blast radius of misuse is minimal—an attacker gains only informational knowledge about configured billing providers, which does not compromise system integrity or financial operations.
From the tool's definition Tool name 'billing_providers_list' and description 'List all infrastructure billing providers' indicate a read-only operation that retrieves existing data without modification, deletion, or financial transactions.
Documented attack patterns abuse exactly the kind of access billing_providers_list 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 billing_providers_list:
{
"version": "1",
"default": "deny",
"tools": {
"billing_providers_list": {}
}
}billing_providers_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all infrastructure billing providers. 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 billing_providers_list: 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.
billing_providers_list 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 billing_providers_list 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 billing_providers_list. 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.
billing_providers_list 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.
