WHAT IT DOES

What list_instance_nodebalancers does on Linode MCP Server

RISK

Why list_instance_nodebalancers is rated Low

This is a query/retrieval operation with no side effects. It only reads and returns data about existing NodeBalancer configurations associated with an instance. No infrastructure changes, deletions, or financial operations occur. Confidence is high because the verb 'list' and the passive 'attached to' clearly indicate a read-only operation.

From the tool's definition list_instance_nodebalancers - the name and description indicate this tool retrieves/lists information about NodeBalancers attached to a Linode instance without modifying any resources.
