create_operator · Touchdesigner MCP: Risk & Policy

WHAT IT DOES

What create_operator does on Touchdesigner

AI agents use create_operator to create or update resources in Touchdesigner — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Touchdesigner environment.

WHY IT NEEDS A POLICY

Why create_operator needs a policy

This tool creates a new operator in TouchDesigner, which is a reversible write operation. It adds a new node/operator to the scene graph but does not delete or overwrite existing data. Misuse could clutter or corrupt a project but the operation is generally reversible by deleting the created operator.

Verdict

create_operator Rate-limited

create_operator 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.
