# list_firewall_rules A read tool on the CloudStack MCP Server MCP server. Agent View of the PolicyLayer registry record for `list_firewall_rules`. HTML page: https://policylayer.com/tools/mozg31337-cloudstack-mcp-server/list-firewall-rules ## Facts - Tool: `list_firewall_rules` - 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_firewall_rules", "arguments": {} } } ``` ## Why list_firewall_rules is rated Low This tool retrieves and displays firewall rule configurations. It has no side effects—it does not create, modify, delete, or execute any changes to the infrastructure. Listing firewall rules is a read-only query operation with minimal security risk unless the rules themselves contain sensitive information about network security policies, which would be informational rather than operationally dangerous. From the tool's own definition: "Tool name is 'list_firewall_rules' and description states 'List firewall rules'. The verb 'list' is a retrieval operation that queries existing firewall rules without modifying, deleting, or executing any infrastructure changes." ## Use case AI agents call list_firewall_rules 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_firewall_rules": {} } } ``` ## 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.
