wait_pilot_agent · Helix Pilot MCP: Risk & Policy

WHAT IT DOES

What wait_pilot_agent does on Helix Pilot

AI agents invoke wait_pilot_agent to trigger actions in Helix Pilot. 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 wait_pilot_agent needs a policy

wait_pilot_agent triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

wait_pilot_agent Rate-limited

wait_pilot_agent 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.
