WHAT IT DOES

What execute_context_script does on Blender Mcp Enhanced

AI agents invoke execute_context_script to trigger actions in Blender Mcp Enhanced. 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 execute_context_script needs a policy

execute_context_script 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.

execute_context_script Rate-limited
