What create_transition does on Aos
AI agents use create_transition 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 create_transition is rated Medium
This tool creates a new parameterized transition component (baseCOMP) in the TouchDesigner project. It is a Write operation because it adds a new, reversible artifact to the project graph. While it 'executes' a creative operation, the core action is creating/constructing a node rather than running code or commands with unpredictable side effects.
From the tool's definition 'Build a parameterized A→B transition' and 'Creates a new baseCOMP under' — the tool creates a new node/component in the TouchDesigner network
Attacks that exploit this kind of access
The rule that runs create_transition 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_transition, this is the rule to start with:
create_transition 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_transition call is checked against it from then on.
Questions about create_transition
Build a parameterized A→B transition over a single 0–1 Progress knob — the executable core of VJ cutting. Creates a new baseCOMP under. 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 create_transition: 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.
create_transition 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 create_transition 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 create_transition. 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.
create_transition 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.
