List notes in Apple Notes, optionally filtered by folder
AI agents call list_notes to retrieve information from Apple Notes MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and enumerates notes from the Notes app, potentially filtered by folder. It performs no modifications, deletions, or external operations. This is a straightforward Read operation with minimal security risk—the worst case is information disclosure of note contents the agent already has access to.
From the tool's definition Tool name is 'list_notes' and description states it 'List notes in Apple Notes, optionally filtered by folder'. This is a query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_notes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apple Notes MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_notes:
{
"version": "1",
"default": "deny",
"tools": {
"list_notes": {}
}
}list_notes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Apple Notes MCP Server MCP server in PolicyLayer and add a rule for list_notes: 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 Server. Nothing to install.
list_notes is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_notes 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 list_notes. 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.
list_notes is provided by the Apple Notes MCP Server MCP server (rodriguesjohn/applenotesmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apple Notes MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
