What create_container does on tdmcp — TouchDesigner MCP server
AI agents use create_container to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.
Why create_container is rated Medium
This tool creates a new component (COMP) container in TouchDesigner, which is a reversible operation that adds to the visual system structure. It modifies the parent node graph by inserting and arranging a new element, but does not execute arbitrary code, delete data, or trigger financial transactions. The effect is bounded to creating one container and repositioning it, making it a Write operation.
From the tool's definition Tool description states "Create one empty COMP under parent_path" and "tile it into the parent". The verbs "create" and "tile" indicate data creation and modification within TouchDesigner's node graph.
Attacks that exploit this kind of access
The rule that runs create_container 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_container, this is the rule to start with:
create_container 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 tdmcp — TouchDesigner MCP server, apply this rule, and every create_container call is checked against it from then on.
Questions about create_container
Create one empty COMP under parent_path to hold a visual system, then tile it into the parent. It is categorised as a Write tool in the tdmcp — TouchDesigner MCP server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_container: 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_container is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_container 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_container. 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_container 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.
