AI agents call rollup to permanently remove resources in MCP Notes — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call rollup doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from MCP Notes is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
Synthesize my daily note to create an organized rollup of the most important notes with clear categories, connections, and action items. Optionally specify a date (YYYY-MM-DD). Only include notes that actually add long-term value. If you are unsure, call the /evaluateInsight tool to evaluate the long-term value of the thought. If you do not have enough information, stop and ask the user for more information. It is better to not log anything than log something that is not useful. It is categorised as a Destructive tool in the MCP Notes MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Notes MCP server in PolicyLayer and add a rule for rollup: 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 MCP Notes. Nothing to install.
rollup 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 rollup 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 rollup. 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.
rollup is provided by the MCP Notes MCP server (mikeysrecipes/mcp-notes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
