AI agents may call delete_calendar 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_calendar 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.

Permanently delete a calendar and all its events. WARNING: This action cannot be undone! Use this when user explicitly asks to. 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_calendar: 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_calendar 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_calendar 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_calendar. 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_calendar 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.
