# create_optical_flow

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

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "create_optical_flow",
    "arguments": {}
  }
}
```

## 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 own 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"

## Use case

AI agents use create_optical_flow to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Aos:
