WHAT IT DOES

What update_k8s_cluster_version does on Timeweb

AI agents use update_k8s_cluster_version 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
`cluster_id`	integer	Yes	ОБЯЗАТЕЛЬНОЕ ПОЛЕ - ID кластера
`k8s_version`	string	—	Новая версия Kubernetes (например, v1.33.4+k0s.0). Получить список через list_k8s_versions.

Parameters from the server's own tool schema.

RISK

Why update_k8s_cluster_version is rated Medium

An AI agent can call update_k8s_cluster_version faster than any human can review: one bad instruction and it creates or modifies resources in Timeweb by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs update_k8s_cluster_version 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 update_k8s_cluster_version, this is the rule to start with:

update_k8s_cluster_version Rate-limited

update_k8s_cluster_version 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.
