Create a new Apple Note with specified title and content. Must be in HTML format WITHOUT newlines
AI agents use create-note to create or update resources in MCP Apple Notes — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Apple Notes environment.
This tool creates new notes, which is a Write operation—it modifies the user's data store by adding new entries. It is reversible (notes can be deleted), so it does not qualify as Destructive. The severity is low because note creation has no blast radius beyond adding potentially unwanted notes to the user's personal notes collection, which can be manually removed.
From the tool's definition The tool description states 'Create a new Apple Note with specified title and content,' which is a create operation that adds new data reversibly to Apple Notes.
Documented attack patterns abuse exactly the kind of access create-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 create-note:
{
"version": "1",
"default": "deny",
"tools": {
"create-note": {
"limits": [
{
"counter": "create-note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-note stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new Apple Note with specified title and content. Must be in HTML format WITHOUT newlines. It is categorised as a Write tool in the MCP Apple Notes MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Apple Notes MCP server in PolicyLayer and add a rule for create-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.
create-note is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create-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 create-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.
create-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.
