WHAT IT DOES

What create_flow_abstraction does on tdmcp — TouchDesigner MCP server

AI agents use create_flow_abstraction 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_flow_abstraction is rated Medium

The tool creates and modifies project structures (glslTOPs, textDATs, Select TOP, Null TOP, and parameter bindings) within TouchDesigner's node graph. These are reversible operations—the created nodes can be deleted or modified later. While it executes shader code, the primary effect is structural creation of visual pipeline components.

From the tool's definition Creates two glslTOPs + companion textDATs under parent_path, fed by a Select TOP from the source TOP and terminated by a Null TOP. Strength/Edge/Iterations are exposed as live parent-par-bound uniforms.

RECOMMENDED RULE

The rule that runs create_flow_abstraction 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_flow_abstraction, this is the rule to start with:

create_flow_abstraction Rate-limited

create_flow_abstraction 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_flow_abstraction call is checked against it from then on.

FAQ

Questions about create_flow_abstraction

What does the create_flow_abstraction tool do? +

Build a two-pass Kyprianidis-style flow abstraction: an edge-tangent-flow (ETF) bilateral smoother followed by a flow-based DoG (FDoG) line extractor — oil-painting smooth interiors with crisp coherent ink edges. Creates two glslTOPs + companion textDATs under parent_path, fed by a Select TOP from the source TOP and terminated by a Null TOP. Strength/Edge/Iterations are exposed as live parent-par-bound uniforms; blur radius, sigmas and tau are baked in at build time. Iterations boosts effective ETF strength in-shader (single-input pass, no ping-pong feedback). 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_flow_abstraction? +

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

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

Can I rate-limit create_flow_abstraction? +

Yes. Add a rate_limit block to the create_flow_abstraction 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_flow_abstraction completely? +

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

create_flow_abstraction 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.
