List cached note entries from a previously synced folder, optionally filtered by year.
AI agents call note_list to retrieve information from MCP Apple Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing notes from a cached folder without creating, modifying, deleting, or executing any operations. The optional year filtering parameter is a read-time query constraint with no side effects. Listing/querying data is the definition of the Read category.
