WHAT IT DOES

What reactivate_agent does on Lightning Wallet

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

RISK

Why reactivate_agent is rated Medium

This tool creates or modifies data reversibly—specifically, the active/inactive state of an agent. While it requires privileged access (OPERATOR KEY), it does not irreversibly delete data (Destructive), execute arbitrary code (Execute), or move funds (Financial).

From the tool's definition Reactivate a previously deactivated agent. REQUIRES OPERATOR KEY. The tool modifies the state of an agent (from deactivated to active) but does not destroy data or move funds.

RECOMMENDED RULE

The rule that runs reactivate_agent safely

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

reactivate_agent Rate-limited

reactivate_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.
