WHAT IT DOES

What delete_vpc_subnet does on Linode MCP Server

AI agents call delete_vpc_subnet to permanently remove resources in Linode MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_vpc_subnet is rated Critical

This tool permanently removes a VPC subnet and its associated configuration from Linode infrastructure. Deletion of network infrastructure is irreversible and could disrupt services, isolate compute instances, or cause data access issues. While not directly financial, the blast radius is significant as it affects network topology and availability of dependent resources.

From the tool's definition Tool name 'delete_vpc_subnet' and description 'Delete a subnet in a VPC' explicitly perform a deletion operation that cannot be reversed.

RECOMMENDED RULE

The rule that runs delete_vpc_subnet safely

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

delete_vpc_subnet Hidden

delete_vpc_subnet is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
