# create_ipv4_subnet_for_zone A write tool on the CloudStack MCP Server MCP server. Agent View of the PolicyLayer registry record for `create_ipv4_subnet_for_zone`. HTML page: https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/create-ipv4-subnet-for-zone ## Facts - Tool: `create_ipv4_subnet_for_zone` - Server: CloudStack MCP Server (`mozg31337/cloudstack-mcp-server`) — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server.md - Homepage: https://github.com/mozg31337/cloudstack-mcp-server - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "create_ipv4_subnet_for_zone", "arguments": {} } } ``` ## Why create_ipv4_subnet_for_zone is rated Medium This tool creates a new IPv4 subnet, which is a reversible Write operation. It does not execute arbitrary code (Execute), delete resources (Destructive), or move money (Financial). While creating network infrastructure has operational impact, it can be modified or removed later. The medium severity reflects that misconfigured subnets could disrupt network connectivity but are not irreversible or financially damaging. From the tool's own definition: "Tool name is 'create_ipv4_subnet_for_zone' and description states 'Create IPv4 subnet for zone'. The verb 'create' and the action of establishing a new subnet are Write operations that modify infrastructure configuration." ## Use case AI agents use create_ipv4_subnet_for_zone to create or update resources in CloudStack MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CloudStack MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CloudStack MCP Server: ```json { "version": "1", "default": "deny", "tools": { "create_ipv4_subnet_for_zone": { "limits": [ { "counter": "create_ipv4_subnet_for_zone_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on CloudStack MCP Server (441) - `cancel_host_maintenance` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/cancel-host-maintenance.md - `delete_account` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-account.md - `delete_account_from_project` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-account-from-project.md - `delete_alerts` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-alerts.md - `delete_application_load_balancer` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-application-load-balancer.md - `delete_bgp_peer` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-bgp-peer.md - `delete_customer_gateway` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-customer-gateway.md - `delete_dhcp_option` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-dhcp-option.md - `delete_disk_offering` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-disk-offering.md - `delete_domain` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-domain.md - `delete_egress_firewall_rule` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-egress-firewall-rule.md - `delete_firewall_rule` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-firewall-rule.md - `delete_global_load_balancer` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-global-load-balancer.md - `delete_host` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-host.md - `delete_image_store` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-image-store.md - `delete_ip_forwarding_rule` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-ip-forwarding-rule.md - `delete_ipv4_subnet_for_guest_network` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-ipv4-subnet-for-guest-network.md - `delete_ipv4_subnet_for_zone` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-ipv4-subnet-for-zone.md - `delete_ipv6_firewall_rule` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-ipv6-firewall-rule.md - `delete_iso` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-iso.md - `delete_kubernetes_cluster` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-kubernetes-cluster.md - `delete_kubernetes_supported_version` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-kubernetes-supported-version.md - `delete_lb_health_check_policy` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-lb-health-check-policy.md - `delete_lb_stickiness_policy` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-lb-stickiness-policy.md - `delete_load_balancer_rule` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-load-balancer-rule.md - `delete_network` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-network.md - `delete_network_acl` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-network-acl.md - `delete_network_acl_list` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-network-acl-list.md - `delete_network_device` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-network-device.md - `delete_network_offering` — Destructive — https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/delete-network-offering.md - …and 411 more: https://policylayer.com/tools/mozg31337-cloudstack-mcp-server.md ## For agents This record is a snapshot.
