WHAT IT DOES

What archive_card does on Superthread Mcp Extended

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

WHY IT NEEDS A POLICY

Why archive_card needs a policy

Archiving is a Write operation because it modifies card state reversibly; the card remains in the system but transitions to an archived status. This is not Destructive (data is recoverable/unarchivable), not Execute (no code/command execution), not Read (causes side effects), and not Financial.

From the tool's definition Tool performs 'Archive a card' — archives are reversible state changes that hide but do not permanently delete data, consistent with Write operations like update or modify.
