Retrieve all folders with names and identifiers
AI agents call notes-get-folders to retrieve information from Notes MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about folders (names and identifiers) from Apple Notes without creating, modifying, deleting, or executing any operations. It is a purely informational read operation with no side effects. The blast radius if misused by an AI agent would be limited to information disclosure of folder structure.
From the tool's definition Tool name 'notes-get-folders' and description 'Retrieve all folders with names and identifiers' indicate a query operation that retrieves data without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and Notes MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for notes-get-folders:
{
"version": "1",
"default": "deny",
"tools": {
"notes-get-folders": {}
}
}notes-get-folders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
