# list_os_types List supported OS types Agent View of the PolicyLayer registry record for `list_os_types`. HTML page: https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/list-os-types ## Facts - Tool: `list_os_types` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "list_os_types", "arguments": {} } } ``` ## Why list_os_types is rated Low This tool performs a read-only operation to enumerate supported OS types in the CloudStack infrastructure. It has no capability to modify, delete, or execute operations. The blast radius of misuse is minimal since it only returns configuration information. Classification as Read is appropriate. From the tool's own definition: "Tool name is 'list_os_types' and description states 'List supported OS types' — this is a query operation that retrieves information about available operating system types without any data modification or side effects." ## Use case AI agents call list_os_types to retrieve information from CloudStack MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches CloudStack MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_os_types": {} } } ``` ## 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.
