What create_visual_system does on tdmcp — TouchDesigner MCP server
AI agents invoke create_visual_system to trigger actions in tdmcp — TouchDesigner MCP server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why create_visual_system is rated High
This tool triggers complex external operations in TouchDesigner — building network nodes, instantiating components, executing builder logic, and launching previews — based on arbitrary natural-language input. The effects depend heavily on arguments (the description and parent_path), and the tool orchestrates multiple sub-operations including classification, delegation, construction, verification, and preview.
From the tool's definition 'Create a complete visual system from a natural-language description... delegates to the matching Layer-1 builder (or a tag-matched recipe), creating a self-contained COMP under parent_path, then verifies and previews it'
Attacks that exploit this kind of access
The rule that runs create_visual_system safely
PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_visual_system, this is the rule to start with:
create_visual_system stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect tdmcp — TouchDesigner MCP server, apply this rule, and every create_visual_system call is checked against it from then on.
Questions about create_visual_system
Create a complete visual system from a natural-language description. Classifies intent (audio-reactive, particle, feedback, reaction-diffusion, landscape, generative) and delegates to the matching Layer-1 builder (or a tag-matched recipe), creating a self-contained COMP under parent_path, then verifies and previews it. Use plan_visual instead for a dry run that reports which tool/recipe would be chosen without building anything. Returns a note on how the description was interpreted plus the underlying builder. It is categorised as a Execute tool in the tdmcp — TouchDesigner MCP server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_visual_system: 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 tdmcp — TouchDesigner MCP server. Nothing to install.
create_visual_system is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the create_visual_system 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.
Set action: deny in the PolicyLayer policy for create_visual_system. 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.
create_visual_system is provided by the tdmcp — TouchDesigner MCP server MCP server (@dpantani/tdmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
