AI agents use billing_provider_create 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 a new billing provider, which is a reversible write operation that modifies the billing infrastructure. It has high severity because misconfigured or malicious billing providers could redirect payments, expose financial data, or disrupt the billing system.
From the tool's definition Tool name is 'billing_provider_create' and description states 'Create a new billing provider'. The 'create' action modifies system state by adding a new billing provider configuration.
Documented attack patterns abuse exactly the kind of access billing_provider_create 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_provider_create:
{
"version": "1",
"default": "deny",
"tools": {
"billing_provider_create": {
"limits": [
{
"counter": "billing_provider_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}billing_provider_create 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.
Create a new billing provider. 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 billing_provider_create: 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_provider_create 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 billing_provider_create 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_provider_create. 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_provider_create 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.
