What reduce_k8s_node_group_nodes does on Timeweb
AI agents call reduce_k8s_node_group_nodes to permanently remove resources in Timeweb, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
| Parameter | Type | Required | Description |
|---|---|---|---|
count | integer | Yes | ОБЯЗАТЕЛЬНОЕ ПОЛЕ - количество удаляемых нод |
group_id | integer | Yes | ОБЯЗАТЕЛЬНОЕ ПОЛЕ - ID группы нод |
cluster_id | integer | Yes | ОБЯЗАТЕЛЬНОЕ ПОЛЕ - ID кластера |
Parameters from the server's own tool schema.
Why reduce_k8s_node_group_nodes is rated Critical
The description explicitly states the action is irreversible and deleted nodes cannot be restored. Removing Kubernetes worker nodes from a cluster group is a destructive operation with high blast radius — workloads running on those nodes will be disrupted and the nodes cannot be recovered.
From the tool's definition Действие необратимо — удалённые ноды нельзя восстановить

The rule that runs reduce_k8s_node_group_nodes 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 reduce_k8s_node_group_nodes, this is the rule to start with:
reduce_k8s_node_group_nodes is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Timeweb, apply this rule, and every reduce_k8s_node_group_nodes call is checked against it from then on.
Questions about reduce_k8s_node_group_nodes
Удаляет указанное количество воркер-нод из группы. Действие необратимо — удалённые ноды нельзя восстановить. It is categorised as a Destructive tool in the Timeweb MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
reduce_k8s_node_group_nodes accepts 3 parameters: count, group_id, cluster_id. Required: count, group_id, cluster_id. The full parameter table on this page comes from the server's own tool schema.
Register the Timeweb MCP server in PolicyLayer and add a rule for reduce_k8s_node_group_nodes: 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.
reduce_k8s_node_group_nodes is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the reduce_k8s_node_group_nodes 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 reduce_k8s_node_group_nodes. 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.
reduce_k8s_node_group_nodes 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.
