What unarchive_agent does on Todos
AI agents use unarchive_agent 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.
Why unarchive_agent is rated Medium
This tool modifies agent state from archived to active, which is reversible and represents data mutation. While the impact is relatively contained to agent lifecycle management, it could affect task assignments or workflows if misused by an AI agent (e.g., restoring unwanted agents). The medium severity reflects moderate blast radius in a task management context.
From the tool's definition The tool 'unarchive_agent' performs a state change operation: 'Restore an archived agent back to active status.' This is a modification that reverses a previous archival action, making it a Write operation rather than a Read (no retrieval-only) or Destructive…
Attacks that exploit this kind of access
The rule that runs unarchive_agent 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_agent, this is the rule to start with:
unarchive_agent 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every unarchive_agent call is checked against it from then on.
