AI agents may call cancel_scheduled_snapshot to permanently remove or destroy resources in BorealHost. 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 cancel_scheduled_snapshot in a loop, permanently destroying resources in BorealHost. 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.

Cancel a scheduled snapshot. Requires: API key with write scope. Args: slug: Site identifier schedule_id: UUID of the scheduled snapshot to cancel Returns: {"success": true, "message": "Scheduled snapshot cancelled"} Errors: NOT_FOUND: Schedule not found or already executed. It is categorised as a Destructive tool in the BorealHost MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the BorealHost MCP server in PolicyLayer and add a rule for cancel_scheduled_snapshot: 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 BorealHost. Nothing to install.
cancel_scheduled_snapshot 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 cancel_scheduled_snapshot 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 cancel_scheduled_snapshot. 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.
cancel_scheduled_snapshot is provided by the BorealHost MCP server (pypi:borealhost-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
