wait_for_reply · Telegram MCP: Risk & Policy

WHAT IT DOES

What wait_for_reply does on Telegram

AI agents invoke wait_for_reply to trigger actions in Telegram. 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_for_reply needs a policy

wait_for_reply 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.

wait_for_reply Rate-limited
