User preference memory operations.\n\nActions:\n- list: List/search stored memories\n- save: Save a new memory (requires content)\n- update: Update memory content/tags (requires id)\n- delete: Delete a memory (requires id)
AI agents call noteplan_memory to permanently remove resources in Noteplan — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool spans multiple categories including delete (Destructive), save/update (Write), and list (Read). Per rules, the most severe applicable category takes precedence. The delete action irreversibly removes stored memory entries, making this Destructive.
From the tool's definition Actions include 'delete: Delete a memory (requires id)' alongside read/write operations

User preference memory operations.\n\nActions:\n- list: List/search stored memories\n- save: Save a new memory (requires content)\n- update: Update memory content/tags (requires id)\n- delete: Delete a memory (requires id). It is categorised as a Destructive tool in the Noteplan MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Noteplan MCP server in PolicyLayer and add a rule for noteplan_memory: 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 Noteplan. Nothing to install.
noteplan_memory 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 noteplan_memory 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 noteplan_memory. 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.
noteplan_memory is provided by the Noteplan MCP server (@noteplanco/noteplan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
