notes_sync_full · Macnotes MCP: Risk & Policy

WHAT IT DOES

What notes_sync_full does on Macnotes

AI agents invoke notes_sync_full to trigger actions in Macnotes. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why notes_sync_full needs a policy

This tool triggers an external operation (Notes.app sync) whose effects depend on the state of Notes.app and result in cache modifications. It is not merely reading (it modifies cache), not writing user data directly, not destructive (sync is reversible), and not financial. It is an Execute action because it runs a background process/operation.

From the tool's definition Tool performs 'Run a full sync from Notes.app into the local cache' — executes a background operation that triggers synchronization between Notes.app and the cache, with side effects on the local cache state.
