AI agents use rollup to create or update resources in MCP Notes — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Notes environment.
The rollup tool synthesizes daily notes and creates an organized output, implying it writes/creates new structured content (a rollup document) from existing notes. References to 'log' and creating organized notes with categories and action items suggest it produces new written artifacts. It is reversible (notes can be deleted or overwritten), so Write is the appropriate category rather than Destructive.
From the tool's definition Synthesize my daily note to create an organized rollup... Only include notes that actually add long-term value... log anything
Documented attack patterns abuse exactly the kind of access rollup gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Notes, and nothing reaches the server without passing your rules. This is the rule we recommend for rollup:
{
"version": "1",
"default": "deny",
"tools": {
"rollup": {
"limits": [
{
"counter": "rollup_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rollup stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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 Write tool in the MCP Notes MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
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 Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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 (markacianfrani/mcp-notes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Notes, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
