WHAT IT DOES

What create_layer_stack does on Aos

AI agents use create_layer_stack 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.

RISK

Why create_layer_stack is rated Medium

This tool creates and configures a network of nodes (Select TOPs, Level TOPs, Composite TOPs, Null) in TouchDesigner. It builds/creates a new structure but does not delete data, execute arbitrary code, or move money.

From the tool's definition Build a VJ-style N-layer compositor: stack 2–8 source TOPs and composite them bottom-up... Exposes a live control strip... ends on a Null ready for post-processing or setup_output

RECOMMENDED RULE

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

create_layer_stack Rate-limited

create_layer_stack 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 create_layer_stack call is checked against it from then on.

FAQ

Questions about create_layer_stack

What does the create_layer_stack tool do? +

Build a VJ-style N-layer compositor: stack 2–8 source TOPs and composite them bottom-up, each layer with its own blend mode (over/add/multiply/screen/difference/lighten/darken) and opacity. Each layer is a Select TOP (or a built-in test source when omitted) → a Level TOP carrying opacity; layers above the base each get their own 2-input Composite TOP so blend modes are per-layer. Exposes a live control strip — per layer: Opacity (0–1), Blend (menu), Mute, Solo — and ends on a Null ready for post-processing or setup_output. Pass. 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.

How do I enforce a policy on create_layer_stack? +

Register the Aos MCP server in PolicyLayer and add a rule for create_layer_stack: 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.

What risk level is create_layer_stack? +

create_layer_stack is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_layer_stack? +

Yes. Add a rate_limit block to the create_layer_stack 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.

How do I block create_layer_stack completely? +

Set action: deny in the PolicyLayer policy for create_layer_stack. 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.

What MCP server provides create_layer_stack? +

create_layer_stack 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.
