List firewall rules
AI agents call list_firewall_rules to retrieve information from CloudStack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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 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.

List firewall rules. It is categorised as a Read tool in the CloudStack MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for list_firewall_rules: 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.
list_firewall_rules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_firewall_rules 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 list_firewall_rules. 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.
list_firewall_rules 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.
