WHAT IT DOES

What unarchive_task does on Todos

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

RISK

Why unarchive_task is rated Medium

This tool modifies task metadata reversibly by changing a task's status/state from archived back to pending. This is a Write operation because it creates or modifies data reversibly without destructive or financial consequences. Severity is medium because an agent misusing this could restore many archived tasks unintentionally, cluttering the task system, but changes are reversible (the task can be re-archived).

From the tool's definition Tool name 'unarchive_task' and description 'Restore an archived task back to pending' indicate modification of task state from archived to pending status.

RECOMMENDED RULE

The rule that runs unarchive_task safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unarchive_task, this is the rule to start with:

unarchive_task Rate-limited

unarchive_task stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
