Get the full content of a note by its unique ID
AI agents call get_note_by_id 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 performs a read-only operation that fetches note content by ID. It has no side effects, does not modify data, and does not execute code or trigger external operations. The blast radius of misuse is minimal—an agent could only access existing note content it has permission to read.
From the tool's definition Tool name 'get_note_by_id' and description 'Get the full content of a note by its unique ID' indicate retrieval without modification. This is a pure query operation that retrieves existing data.

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 get_note_by_id:
{
"version": "1",
"default": "deny",
"tools": {
"get_note_by_id": {}
}
}get_note_by_id 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 get_note_by_id: 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.
get_note_by_id 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_by_id 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_by_id. 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_by_id 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.
