safari_reload · MacWright MCP: Risk & Policy

WHAT IT DOES

What safari_reload does on MacWright

AI agents invoke safari_reload to trigger actions in MacWright. 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 safari_reload needs a policy
