AI agents call defense_stats to retrieve information from Novyx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information about defenses without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk to the system. The read-only nature and informational purpose place it firmly in the Read category with low severity.
From the tool's definition Tool name 'defense_stats' and description 'Get overall defense statistics' indicates a retrieval operation with no modification or execution of external systems. The verb 'Get' clearly signals a read-only query.
Documented attack patterns abuse exactly the kind of access defense_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novyx, and nothing reaches the server without passing your rules. This is the rule we recommend for defense_stats:
{
"version": "1",
"default": "deny",
"tools": {
"defense_stats": {}
}
}defense_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get overall defense statistics. It is categorised as a Read tool in the Novyx MCP Server, which means it retrieves data without modifying state.
Register the Novyx MCP server in PolicyLayer and add a rule for defense_stats: 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 Novyx. Nothing to install.
defense_stats 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 defense_stats 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 defense_stats. 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.
defense_stats is provided by the Novyx MCP server (novyxlabs/novyx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
