List all Apple Reminders lists with account name, color, and modification status.
AI agents call reminders.list_lists 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 tool retrieves and queries reminder list information from the user's Apple Reminders application. It performs no write, delete, execute, or financial operations. The action is purely informational and read-only, making it a Read category tool with low severity since it only exposes list metadata without sensitive data exfiltration capabilities beyond what the user already has access to locally.
From the tool's definition Tool name 'list_lists' and description 'List all Apple Reminders lists' indicate data retrieval with no modification. Returns metadata (account name, color, modification status) about existing reminders lists without side effects.

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 reminders.list_lists:
{
"version": "1",
"default": "deny",
"tools": {
"reminders.list_lists": {}
}
}reminders.list_lists is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
