playcaller_wait · Playcaller MCP: Risk & Policy

WHAT IT DOES

What playcaller_wait does on Playcaller

AI agents invoke playcaller_wait to trigger actions in Playcaller. 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 playcaller_wait needs a policy

playcaller_wait 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

playcaller_wait Rate-limited

playcaller_wait 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.
