WHAT IT DOES

What evaluate_expression does on Adobe Premiere Pro

AI agents use evaluate_expression to create or update resources in Adobe Premiere Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Adobe Premiere Pro environment.

RISK

Why evaluate_expression is rated Medium

An AI agent can call evaluate_expression faster than any human can review: one bad instruction and it creates or modifies resources in Adobe Premiere Pro by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs evaluate_expression 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 evaluate_expression, this is the rule to start with:

evaluate_expression Rate-limited

evaluate_expression stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
