Audit Nanite mesh status for all static meshes in the level.
AI agents call nanite_audit to retrieve information from Uefn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read operation that retrieves information about mesh status. However, severity is elevated to 'medium' rather than 'low' because running audits across all static meshes in a complex level could be computationally expensive or cause performance impacts on the live UEFN editor, presenting a potential denial-of-service risk if invoked repeatedly by an agent.
From the tool's definition Tool performs audit of Nanite mesh status—it queries and inspects existing mesh data in the level without modifying, deleting, or executing external operations. The verb 'audit' indicates inspection/analysis rather than mutation.
Documented attack patterns abuse exactly the kind of access nanite_audit gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Uefn, and nothing reaches the server without passing your rules. This is the rule we recommend for nanite_audit:
{
"version": "1",
"default": "deny",
"tools": {
"nanite_audit": {}
}
}nanite_audit is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Audit Nanite mesh status for all static meshes in the level. It is categorised as a Read tool in the Uefn MCP Server, which means it retrieves data without modifying state.
Register the Uefn MCP server in PolicyLayer and add a rule for nanite_audit: 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 Uefn. Nothing to install.
nanite_audit 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 nanite_audit 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 nanite_audit. 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.
nanite_audit is provided by the Uefn MCP server (quangdang46/uefn-verse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Uefn, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
