List firewall rules with detailed port and address info
AI agents call firewall_rules_detailed to retrieve information from Mcp Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and retrieves firewall configuration information. While it does not modify data (ruling out Write/Destructive), the information exposed could be sensitive—firewall rules reveal network security posture and can inform an attacker about system defenses. Misuse could aid reconnaissance, but the tool itself performs no destructive or active operations.
From the tool's definition 'List firewall rules' indicates retrieval of existing firewall configuration data without modification. The description specifies 'detailed port and address info' which is querying system state.
Documented attack patterns abuse exactly the kind of access firewall_rules_detailed gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for firewall_rules_detailed:
{
"version": "1",
"default": "deny",
"tools": {
"firewall_rules_detailed": {}
}
}firewall_rules_detailed is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List firewall rules with detailed port and address info. It is categorised as a Read tool in the Mcp Windows MCP Server, which means it retrieves data without modifying state.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for firewall_rules_detailed: 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 Mcp Windows. Nothing to install.
firewall_rules_detailed 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 firewall_rules_detailed 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 firewall_rules_detailed. 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.
firewall_rules_detailed is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
