Get firewall groups for security management.
AI agents call get_firewall_groups to retrieve information from UniFi MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves firewall group configuration data from the UniFi controller without modifying, deleting, or executing any operations. It is a read-only query operation used for monitoring and visibility into network security settings. The low severity reflects that unauthorized access to firewall configuration data has limited immediate impact compared to Write, Execute, or Destructive operations.
From the tool's definition Tool name 'get_firewall_groups' with verb 'Get' and description 'Get firewall groups for security management' indicates a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_firewall_groups gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and UniFi MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_firewall_groups:
{
"version": "1",
"default": "deny",
"tools": {
"get_firewall_groups": {}
}
}get_firewall_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get firewall groups for security management. It is categorised as a Read tool in the UniFi MCP MCP Server, which means it retrieves data without modifying state.
Register the UniFi MCP server in PolicyLayer and add a rule for get_firewall_groups: 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 UniFi MCP. Nothing to install.
get_firewall_groups 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 get_firewall_groups 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 get_firewall_groups. 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.
get_firewall_groups is provided by the UniFi MCP server (jmagar/unifi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from UniFi MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
