WHAT IT DOES

What create_time_echo does on Aos

AI agents use create_time_echo 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_time_echo is rated Medium

The tool applies a time-based visual effect (echo trails, slit-scan, per-pixel time displacement) to a source TOP in TouchDesigner. This is a Write-level operation: it creates or modifies nodes/parameters in the project graph. It does not execute arbitrary code, delete data, or involve financial transactions. Marked EXPERIMENTAL, which slightly raises misuse risk but doesn't change category.

From the tool's definition 'Apply a per-pixel time effect to a source TOP: echo trails, slit-scan, or per-pixel time displacement' — creates/applies a visual effect to an existing node

RECOMMENDED RULE

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

create_time_echo Rate-limited

create_time_echo 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_time_echo call is checked against it from then on.

FAQ

Questions about create_time_echo

What does the create_time_echo tool do? +

EXPERIMENTAL — Apply a per-pixel time effect to a source TOP: echo trails, slit-scan, or per-pixel time displacement (the. 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_time_echo? +

Register the Aos MCP server in PolicyLayer and add a rule for create_time_echo: 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_time_echo? +

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

Can I rate-limit create_time_echo? +

Yes. Add a rate_limit block to the create_time_echo 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_time_echo completely? +

Set action: deny in the PolicyLayer policy for create_time_echo. 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_time_echo? +

create_time_echo 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.
