AI agents call network_firewall_rules to retrieve information from Infra Ops 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 existing firewall configurations without modifying, deleting, or executing any changes. It is purely informational in nature, making it a Read operation. The severity is low because viewing firewall rules poses minimal risk—it provides visibility into security posture but cannot alter infrastructure or policies.
From the tool's definition Tool name 'network_firewall_rules' and description 'Display current firewall rules and policies' indicate a query/retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
Display current firewall rules and policies. It is categorised as a Read tool in the Infra Ops MCP Server, which means it retrieves data without modifying state.
Register the Infra Ops MCP server in PolicyLayer and add a rule for network_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 Infra Ops. Nothing to install.
network_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 network_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 network_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.
network_firewall_rules is provided by the Infra Ops MCP server (skyvanguard/infra-ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
