Index all my Apple Notes for Semantic Search. Please tell the user that the sync takes couple of seconds up to couple of minutes depending on how many notes you have.
AI agents call index-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 reads Apple Notes and builds a search index for semantic search/RAG purposes. It retrieves and processes existing notes to enable future querying. While it may write an index to local storage, the primary action is reading notes data, and there is no modification of user content. The side effect (building an index) is non-destructive and reversible. Severity is low as it only accesses local notes data.
From the tool's definition Index all my Apple Notes for Semantic Search
Documented attack patterns abuse exactly the kind of access index-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 index-notes:
{
"version": "1",
"default": "deny",
"tools": {
"index-notes": {}
}
}index-notes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Mcp Apple Notes MCP server in PolicyLayer and add a rule for index-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.
index-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 index-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 index-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.
index-notes is provided by the Mcp Apple Notes MCP server (rafalwilinski/mcp-apple-notes). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
