WHAT IT DOES

What reflect_archive_mode does on Memory Bank MCP Server

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

WHY IT NEEDS A POLICY

Why reflect_archive_mode needs a policy

The tool performs documentation archiving (writing/storing data reversibly). While 'reflect' suggests analysis, the key action is archiving (persisting documentation), which is a Write operation. It does not delete (Destructive), execute arbitrary code (Execute), or move funds (Financial).

From the tool's definition 'archive documentation' indicates the tool writes and stores documentation artifacts; the name 'reflect_archive_mode' suggests structured reflection and documentation management operations.
