AI agents call get-note 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 queries existing note data without creating, modifying, deleting, or executing anything. The only capability is fetching content by title, which poses minimal risk even if misused by an AI agent—it could expose private notes but cannot alter or destroy them.
From the tool's definition Tool description states 'Get a note full content and details by title' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get-note 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 get-note:
{
"version": "1",
"default": "deny",
"tools": {
"get-note": {}
}
}get-note 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.
Get a note full content and details by title. 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 get-note: 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.
get-note 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 get-note 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 get-note. 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.
get-note 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.
Start from MCP Apple Notes, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
