WHAT IT DOES

What ae_add_keyframe does on Ae

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

RISK

Why ae_add_keyframe is rated Medium

This tool creates new keyframe data on a layer property in After Effects. It is a reversible write operation (keyframes can be deleted), with medium severity as misuse could corrupt animation timing but does not cause irreversible damage.

RECOMMENDED RULE

The rule that runs ae_add_keyframe safely

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

ae_add_keyframe Rate-limited

ae_add_keyframe 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.
