Remove a guest group from the guest list
AI agents call remove_guest to permanently remove resources in Zola — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call remove_guest doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Zola is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Remove a guest group from the guest list. It is categorised as a Destructive tool in the Zola MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Zola MCP server in PolicyLayer and add a rule for remove_guest: 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 Zola. Nothing to install.
remove_guest 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 remove_guest 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 remove_guest. 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.
remove_guest is provided by the Zola MCP server (zola-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
