WHAT IT DOES

What archive_note does on Bear MCP Server

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

WHY IT NEEDS A POLICY

Why archive_note needs a policy

Archiving modifies note state but is reversible—the note data remains intact and can be restored. This makes it Write rather than Destructive. The severity is medium because misuse could hide important notes from view, but no data is lost and the action is recoverable.

From the tool's definition Tool name 'archive_note' and description 'Archive a note' indicates a state change operation on a note object. Archiving is a reversible modification (notes can typically be unarchived), distinct from deletion.
