Release dedicated IPv4 subnet for zone
AI agents call release_ipv4_subnet_for_zone to permanently remove resources in CloudStack MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Releasing an IPv4 subnet for a zone deallocates network resources that may affect all VMs and services depending on that subnet. This is not easily reversible as it may reassign or invalidate IP addressing for workloads in the zone, making it a destructive operation with high blast radius.
From the tool's definition 'Release dedicated IPv4 subnet for zone' — releasing a dedicated subnet removes/frees the IP address allocation, which is an irreversible network infrastructure change
Attacks that exploit this kind of access
Release dedicated IPv4 subnet for zone. It is categorised as a Destructive tool in the CloudStack MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for release_ipv4_subnet_for_zone: 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 CloudStack MCP Server. Nothing to install.
release_ipv4_subnet_for_zone 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 release_ipv4_subnet_for_zone 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 release_ipv4_subnet_for_zone. 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.
release_ipv4_subnet_for_zone is provided by the CloudStack MCP Server MCP server (mozg31337/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
release_ipv4_subnet_for_zone is one line of CloudStack MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
