WHAT IT DOES

What create_glsl_shader does on tdmcp — TouchDesigner MCP server

AI agents use create_glsl_shader 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.

RISK

Why create_glsl_shader is rated Medium

This tool creates new nodes and DATs in a TouchDesigner project. It writes/creates data (GLSL shader nodes and text DATs) reversibly — the created nodes can be deleted. No code is executed on the host system directly; it places shader source into the TouchDesigner environment. Write is the most appropriate category.

RECOMMENDED RULE

The rule that runs create_glsl_shader 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_glsl_shader, this is the rule to start with:

create_glsl_shader Rate-limited

create_glsl_shader 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_glsl_shader call is checked against it from then on.

FAQ

Questions about create_glsl_shader

What does the create_glsl_shader tool do? +

Create a GLSL TOP under parent_path that renders a custom fragment shader (and optional vertex shader). The shader source is placed in companion Text DATs (. 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.

How do I enforce a policy on create_glsl_shader? +

Register the tdmcp — TouchDesigner MCP server MCP server in PolicyLayer and add a rule for create_glsl_shader: 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_glsl_shader? +

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

Can I rate-limit create_glsl_shader? +

Yes. Add a rate_limit block to the create_glsl_shader 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_glsl_shader completely? +

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

create_glsl_shader 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.
