What create_depth_from_2d does on tdmcp — TouchDesigner MCP server
AI agents use create_depth_from_2d 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_depth_from_2d is rated Medium
This tool creates new nodes/containers in a TouchDesigner project (drops TOX, wires source, exposes output), which constitutes a reversible write/create operation within the project graph. It does not delete existing data, execute arbitrary code, or involve financial transactions. Severity is medium as it modifies the project structure and requires specific GPU hardware.
From the tool's definition drops the TOX into a fresh container, wires the source, exposes a depth Null TOP whose path can be fed directly into create_depth_displacement
Attacks that exploit this kind of access
The rule that runs create_depth_from_2d 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_depth_from_2d, this is the rule to start with:
create_depth_from_2d 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_depth_from_2d call is checked against it from then on.
Questions about create_depth_from_2d
Wraps TDDepthAnything v2 (community TOX by IntentDev) to convert any 2D image/video TOP into a depth map TOP using Depth Anything v2 via NVIDIA TensorRT/ONNX — no Kinect or RealSense required. Given a source TOP path, drops the TOX into a fresh container, wires the source, exposes a depth Null TOP whose path can be fed directly into create_depth_displacement, create_depth_pop_field, or create_depth_silhouette. Requires the user to have installed TDDepthAnything.tox from https://github.com/IntentDev/TDDepthAnything and an NVIDIA GPU with CUDA + TensorRT pre-built weights (.engine/.onnx). NOT supported on macOS. First cook may take 30–60 s for engine compile. Returns container_path, dropped_tox_path, depth_top_path (the key output), source_top_path, output_resolution, model_variant, and warnings. 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_depth_from_2d: 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_depth_from_2d 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_depth_from_2d 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_depth_from_2d. 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_depth_from_2d 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.
