WHAT IT DOES

What create_node_chain does on Aos

AI agents use create_node_chain 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_node_chain is rated Medium

This tool creates new nodes and wires them together in a TouchDesigner network. It is a Write operation (reversible creation of new objects). It does not delete or overwrite existing data, execute arbitrary code, or involve financial transactions. Severity is medium because misuse could clutter or corrupt a project network, though changes are typically reversible by deleting the created nodes.

From the tool's definition 'Create multiple nodes and (optionally) connect them in sequence' — creates new nodes and connections in the TouchDesigner project

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_node_chain Rate-limited

create_node_chain 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_node_chain call is checked against it from then on.

FAQ

Questions about create_node_chain

What does the create_node_chain tool do? +

Create multiple nodes and (optionally) connect them in sequence. Returns all created paths; on failure it stops and reports partial progress without deleting anything. 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_node_chain? +

Register the Aos MCP server in PolicyLayer and add a rule for create_node_chain: 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_node_chain? +

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

Can I rate-limit create_node_chain? +

Yes. Add a rate_limit block to the create_node_chain 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_node_chain completely? +

Set action: deny in the PolicyLayer policy for create_node_chain. 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_node_chain? +

create_node_chain 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.
