AI agents use billing_history_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 billing history entries, which is a write operation that modifies financial records. While it doesn't directly move money (Financial category), it creates permanent billing records that could be used to fabricate charges or misrepresent transaction history. This is a Write operation with high severity due to the potential for financial fraud through record manipulation in a billing context.
From the tool's definition Tool name 'billing_history_create' and description 'Create a billing history entry' indicate data creation. The context of a VPN panel management system with billing functions suggests financial record creation.

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_history_create:
{
"version": "1",
"default": "deny",
"tools": {
"billing_history_create": {
"limits": [
{
"counter": "billing_history_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}billing_history_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.

Create a billing history entry. 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_history_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_history_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_history_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_history_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_history_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.
