connect_operators · Touchdesigner MCP: Risk & Policy

WHAT IT DOES

What connect_operators does on Touchdesigner

AI agents use connect_operators 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 connect_operators needs a policy

This tool creates a connection (wire) between two operators in TouchDesigner. It modifies the node graph by establishing a data link between existing operators. This is a reversible modification (connections can be disconnected), so it falls under Write rather than Execute or Destructive. Misuse could disrupt signal flow or audio/visual pipelines but is generally recoverable.

Verdict

connect_operators Rate-limited

connect_operators 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Touchdesigner, so you can run agents against it safely.

FAQ

Questions about connect_operators

What does the connect_operators tool do? +

Wire source_path's output N into target_path's input M. It is categorised as a Write tool in the Touchdesigner MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on connect_operators? +

Register the Touchdesigner MCP server in PolicyLayer and add a rule for connect_operators: 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 Touchdesigner. Nothing to install.

What risk level is connect_operators? +

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

Can I rate-limit connect_operators? +

Yes. Add a rate_limit block to the connect_operators 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 connect_operators completely? +

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

connect_operators is provided by the Touchdesigner MCP server (mrinalghosh/touchdesigner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
