set-air-target · Defcon MCP: Risk & Policy

WHAT IT DOES

What set-air-target does on Defcon

AI agents invoke set-air-target to trigger actions in Defcon. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why set-air-target needs a policy

This tool issues a command within the DEFCON game to direct an air unit toward a target. It triggers an in-game action with downstream effects (the unit will move/attack), analogous to executing an operation. While scoped to a game simulation, it represents an active command execution rather than a simple data read or write.

set-air-target Rate-limited

set-air-target stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
