Delete a folder by id. This is destructive.
AI agents call folders_delete to permanently remove resources in Apple Notes MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of folders is an irreversible operation that destroys data without possibility of recovery through normal means. Even though the server is local-only and private, the destructive nature of permanently removing user data warrants the 'Destructive' category and 'high' severity, as misuse by an AI agent could result in loss of user notes and organizational structure.
From the tool's definition Tool description explicitly states 'This is destructive.' The tool name 'folders_delete' indicates permanent removal. Combined with the sibling tool 'notes_delete' and the capability to delete folders, this irreversibly removes stored data.
Attacks that exploit this kind of access
Delete a folder by id. This is destructive. It is categorised as a Destructive tool in the Apple Notes MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Apple Notes MCP server in PolicyLayer and add a rule for folders_delete: 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 Apple Notes MCP. Nothing to install.
folders_delete 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 folders_delete 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 folders_delete. 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.
folders_delete is provided by the Apple Notes MCP server (renatoaraujo/apple-notes-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
