auto_archive · Tages MCP: Risk & Policy

WHAT IT DOES

What auto_archive does on Tages

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

WHY IT NEEDS A POLICY

Why auto_archive needs a policy

This tool creates or modifies data reversibly—archived memories can presumably be unarchived or reviewed later. It does not irreversibly delete data (which would be Destructive), nor does it merely read (Read). The action is a state change (active→archived) with potential for reversal, fitting the Write category.

From the tool's definition Tool performs 'auto-archive' which modifies the state of memories by moving them from active storage to archived state.
