WHAT IT DOES

What unarchive_list does on RTM MCP Server

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

WHY IT NEEDS A POLICY

Why unarchive_list needs a policy

Unarchiving a list modifies data state but is a reversible operation—the list can be archived again. This qualifies as Write rather than Destructive. Severity is medium because while the action affects user organization and task visibility, it does not cause data loss, financial impact, or execute arbitrary code. Confidence is high because the operation's intent is unambiguous from the name and description.

From the tool's definition The tool description states 'Unarchive a list' which reverses a prior archival action, modifying the state of a list in Remember The Milk by changing it from archived to active status.
