rebuild_klib_index · Kmp Api Lookup MCP: Risk & Policy

WHAT IT DOES

What rebuild_klib_index does on Kmp Api Lookup

AI agents invoke rebuild_klib_index to trigger actions in Kmp Api Lookup. 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 rebuild_klib_index needs a policy

rebuild_klib_index 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.
