AI agents may call delete_event to permanently remove or destroy resources in Dav. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call delete_event in a loop, permanently destroying resources in Dav. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access delete_event gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Permanently delete a calendar event. WARNING: This action cannot be undone — the event is removed from the server immediately. Use only when the user explicitly requests deletion. Obtain the event URL and etag from list_events or calendar_query first. The etag ensures no conflicting changes occurred since the event was last retrieved.. It is categorised as a Destructive tool in the Dav MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Dav MCP server in PolicyLayer and add a rule for delete_event: 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 Dav. Nothing to install.
delete_event 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 delete_event 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 delete_event. 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.
delete_event is provided by the Dav MCP server (dav-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
