List all Notes folders grouped by account with note counts. Requires Notes.app to be running and Automation permission.
AI agents call notes.list_folders to retrieve information from Orchard without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries the Notes application to enumerate folders and metadata. It retrieves information without creating, modifying, deleting, or executing anything. The requirement for Notes.app to be running and Automation permission reflects necessary access controls, not indicative of a more severe category.
From the tool's definition Tool description states it 'List[s] all Notes folders' - a retrieval operation with no modification or execution of commands. Returns folder structure and note counts with no side effects.
Documented attack patterns abuse exactly the kind of access notes.list_folders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Orchard, and nothing reaches the server without passing your rules. This is the rule we recommend for notes.list_folders:
{
"version": "1",
"default": "deny",
"tools": {
"notes.list_folders": {}
}
}notes.list_folders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all Notes folders grouped by account with note counts. Requires Notes.app to be running and Automation permission. It is categorised as a Read tool in the Orchard MCP Server, which means it retrieves data without modifying state.
Register the Orchard MCP server in PolicyLayer and add a rule for notes.list_folders: 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 Orchard. Nothing to install.
notes.list_folders 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 notes.list_folders 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 notes.list_folders. 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.
notes.list_folders is provided by the Orchard MCP server (l22-io/orchard-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Orchard, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
