WHAT IT DOES

What create_sdf_field does on tdmcp — TouchDesigner MCP server

AI agents invoke create_sdf_field 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.

RISK

Why create_sdf_field is rated High

This tool generates and executes GLSL shader code within TouchDesigner, creating a live programmable rendering pipeline. It runs custom GPU code (GLSL), creates nodes in a visual programming environment, and triggers external operations in TouchDesigner.

From the tool's definition Build a programmable signed-distance-field (SDF) raymarcher in TouchDesigner as a self-contained GLSL TOP... Exposes live CameraZ / Speed / StepCount / Intensity / Rotate / ColorA / ColorB / Background controls and previews the output

RECOMMENDED RULE

The rule that runs create_sdf_field 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_sdf_field, this is the rule to start with:

create_sdf_field Rate-limited

create_sdf_field 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.

FAQ

Questions about create_sdf_field

What does the create_sdf_field tool do? +

Build a programmable signed-distance-field (SDF) raymarcher in TouchDesigner as a self-contained GLSL TOP. Compose a CSG tree of sphere / box / torus primitives with union / intersect / subtract boolean ops and optional smooth blending. Exposes live CameraZ / Speed / StepCount / Intensity / Rotate / ColorA / ColorB / Background controls and previews the output. 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.

How do I enforce a policy on create_sdf_field? +

Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_sdf_field: 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.

What risk level is create_sdf_field? +

create_sdf_field is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_sdf_field? +

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

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

create_sdf_field 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.
