What setLayerKeyframe does on Aos
AI agents use setLayerKeyframe to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.
Why setLayerKeyframe is rated Medium
The name implies creating or modifying animation keyframe data on a layer, which is a reversible write operation. However, the empty description lowers confidence significantly. Based on the server context (After Effects layer management and animation), this most likely writes keyframe data rather than deleting or executing code.
From the tool's definition Tool name 'setLayerKeyframe' suggests setting/creating a keyframe on a layer in After Effects; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs setLayerKeyframe safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For setLayerKeyframe, this is the rule to start with:
setLayerKeyframe 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Aos, apply this rule, and every setLayerKeyframe call is checked against it from then on.
Questions about setLayerKeyframe
setLayerKeyframe is a write tool on the Aos MCP server. It is categorised as a Write tool in the Aos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Aos MCP server in PolicyLayer and add a rule for setLayerKeyframe: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Aos. Nothing to install.
setLayerKeyframe is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the setLayerKeyframe rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for setLayerKeyframe. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
setLayerKeyframe is provided by the Aos MCP server (@hybridlabor-api/aos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
