WHAT IT DOES

What create_envelope_follower does on Aos

AI agents use create_envelope_follower 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_envelope_follower is rated Medium

This tool constructs a new processing chain within TouchDesigner (envelope follower with attack/release and gating), which is a reversible write/create operation. It does not delete data, execute arbitrary code, or involve financial transactions. Severity is medium because misuse could disrupt a live visual system's signal routing, but changes are recoverable.

From the tool's definition 'Build a reactive signal-shaping chain (attack/release envelope + threshold gate or sidechain ducking) from a CHOP channel' — creates new nodes/operators in the TouchDesigner network

RECOMMENDED RULE

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

create_envelope_follower Rate-limited

create_envelope_follower 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.

FAQ

Questions about create_envelope_follower

What does the create_envelope_follower tool do? +

EXPERIMENTAL — Build a reactive signal-shaping chain (attack/release envelope + threshold gate or sidechain ducking) from a CHOP channel, for. 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_envelope_follower? +

Register the Aos MCP server in PolicyLayer and add a rule for create_envelope_follower: 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_envelope_follower? +

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

Can I rate-limit create_envelope_follower? +

Yes. Add a rate_limit block to the create_envelope_follower 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_envelope_follower completely? +

Set action: deny in the PolicyLayer policy for create_envelope_follower. 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_envelope_follower? +

create_envelope_follower 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.
