WHAT IT DOES

What create_test_pattern does on Aos

AI agents use create_test_pattern 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_test_pattern is rated Medium

The tool creates a new network (test-pattern network) within TouchDesigner for projector calibration purposes. This is a Write operation as it creates new data/nodes in the project. It has low severity since it's generating a standalone calibration asset with no destructive, financial, or execution implications beyond adding nodes to the project.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_test_pattern Rate-limited

create_test_pattern 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_test_pattern call is checked against it from then on.

FAQ

Questions about create_test_pattern

What does the create_test_pattern tool do? +

Generate a projector calibration / alignment source — a standalone test-pattern network. 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_test_pattern? +

Register the Aos MCP server in PolicyLayer and add a rule for create_test_pattern: 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_test_pattern? +

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

Can I rate-limit create_test_pattern? +

Yes. Add a rate_limit block to the create_test_pattern 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_test_pattern completely? +

Set action: deny in the PolicyLayer policy for create_test_pattern. 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_test_pattern? +

create_test_pattern 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.
