WHAT IT DOES

What create_optical_flow does on tdmcp — TouchDesigner MCP server

AI agents use create_optical_flow 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_optical_flow is rated Medium

The tool constructs a new processing node (a single-channel TOP) in the TouchDesigner network based on a video source. This is a creative/write operation that adds a new visual processing element to the project. It does not delete data, execute arbitrary code, or involve financial transactions. Severity is medium because misuse could clutter or disrupt the visual network, but effects are reversible.

From the tool's definition 'Build a CPU motion-energy field from a video source' — creates a new TOP node/output in the TouchDesigner network from an input source

RECOMMENDED RULE

The rule that runs create_optical_flow 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_optical_flow, this is the rule to start with:

create_optical_flow Rate-limited

create_optical_flow 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_optical_flow call is checked against it from then on.

FAQ

Questions about create_optical_flow

What does the create_optical_flow tool do? +

Build a CPU motion-energy field from a video source (cheap drop-in for displacement / particle chains; NOT a real dense optical-flow solver). Output is a single-channel TOP: bright = motion, mid-grey = still, computed as. 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_optical_flow? +

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

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

Can I rate-limit create_optical_flow? +

Yes. Add a rate_limit block to the create_optical_flow 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_optical_flow completely? +

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

create_optical_flow 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.
