AI agents call list-notes to retrieve information from MCP Apple Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays note titles without side effects. It is a query/listing operation that does not create, modify, delete, or execute any external operations. The blast radius of misuse is minimal—an agent could see note titles but cannot access content, modify data, or trigger actions.
From the tool's definition Tool name 'list-notes' and description 'Lists just the titles of all my Apple Notes' indicate a retrieval operation that returns metadata without modification.
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 MCP Apple Notes, 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.
Free to start. No card required.
Lists just the titles of all my Apple Notes. It is categorised as a Read tool in the MCP Apple Notes MCP Server, which means it retrieves data without modifying state.
Register the MCP Apple Notes 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 MCP Apple Notes. 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 MCP Apple Notes MCP server (tom-semple/mcp-apple-notes-fixed). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
