WHAT IT DOES

What create_balancer does on Timeweb

AI agents use create_balancer to create or update resources in Timeweb, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Timeweb environment.

Parameter	Type	Required	Description
`algo`	string	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - алгоритм балансировки: roundrobin \| leastconn
`fall`	number	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - порог количества ошибок
`name`	string	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - имя балансировщика (уникальное в аккаунте)
`path`	string	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - путь health-check (напр. /)
`port`	number	—	Порт балансировщика (опц.)
`rise`	number	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - порог количества успешных ответов
`inter`	number	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - интервал проверки
`proto`	string	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - протокол: http \| http2 \| https \| tcp
`is_ssl`	boolean	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - требуется ли перенаправление на SSL
`maxconn`	number	—	Максимальное количество соединений (опц.)
`timeout`	number	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - таймаут ответа балансировщика
`is_sticky`	boolean	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - сохранять ли сессию

RISK

Why create_balancer is rated Medium

This tool creates a new load balancer resource, which is a reversible write operation. It modifies infrastructure state by adding a new managed resource but does not execute arbitrary code, delete data, or commit financial transactions. The severity is medium because misconfiguration could redirect traffic or cause service disruption, but the action itself is recoverable by deletion.

From the tool's definition Tool name is 'create_balancer' and description states 'Создаёт новый балансировщик нагрузки' (Creates a new load balancer). The action is to create/instantiate a new cloud infrastructure resource with configuration parameters.

RECOMMENDED RULE

The rule that runs create_balancer safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Timeweb, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_balancer, this is the rule to start with:

create_balancer Rate-limited

create_balancer 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_balancer": {
      "limits": [
        {
          "counter": "create_balancer_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Timeweb, apply this rule, and every create_balancer call is checked against it from then on.

FAQ

Questions about create_balancer

What does the create_balancer tool do? +

What parameters does create_balancer accept? +

create_balancer accepts 12 parameters: algo, fall, name, path, port, rise, inter, proto, is_ssl, maxconn, timeout, is_sticky. Required: algo, fall, name, path, rise, inter, proto, is_ssl, timeout, is_sticky. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on create_balancer? +

Register the Timeweb MCP server in PolicyLayer and add a rule for create_balancer: 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 Timeweb. Nothing to install.

What risk level is create_balancer? +

create_balancer is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_balancer? +

Yes. Add a rate_limit block to the create_balancer 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.

How do I block create_balancer completely? +

Set action: deny in the PolicyLayer policy for create_balancer. 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.

What MCP server provides create_balancer? +

create_balancer is provided by the Timeweb MCP server (timeweb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
