What shutdown does on Uefn
AI agents call shutdown to permanently remove resources in Uefn, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why shutdown is rated Critical
Shutting down the MCP listener terminates the bridge process that connects MCP clients to the live UEFN editor. This is an irreversible action in context — it kills a running service and would disrupt all ongoing operations, requiring manual restart. It cannot be 'undone' automatically; the service must be restarted explicitly.

The rule that runs shutdown safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Uefn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For shutdown, this is the rule to start with:
shutdown is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Uefn, apply this rule, and every shutdown call is checked against it from then on.
Questions about shutdown
Stop the MCP listener. It is categorised as a Destructive tool in the Uefn MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Uefn MCP server in PolicyLayer and add a rule for shutdown: 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.
shutdown is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the shutdown 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 shutdown. 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.
shutdown 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.
