notes_move · Macnotes MCP: Risk & Policy

WHAT IT DOES

What notes_move does on Macnotes

AI agents use notes_move to create or update resources in Macnotes — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Macnotes environment.

WHY IT NEEDS A POLICY

Why notes_move needs a policy

The tool modifies note metadata (folder location) reversibly without deleting data. This is a Write operation: it changes state but the action can be undone by moving the note to its original folder. Severity is medium because misuse could reorganize user's note structure, but notes remain intact and the action is reversible. Confidence is high due to explicit 'write' language in the description.

From the tool's definition Tool name 'notes_move' and description 'Move a note to a different folder' clearly indicates modification of note organization state. Description explicitly states '(queued background write by default)' confirming write classification.
