WHAT IT DOES

What execute_extendscript does on Adobe Premiere Pro

AI agents invoke execute_extendscript to trigger actions in Adobe Premiere Pro. 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.

RISK

Why execute_extendscript is rated High

execute_extendscript 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs execute_extendscript safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Adobe Premiere Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For execute_extendscript, this is the rule to start with:

execute_extendscript Rate-limited

execute_extendscript 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.

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Adobe Premiere Pro, apply this rule, and every execute_extendscript call is checked against it from then on.
