WHAT IT DOES

What caption_top does on tdmcp — TouchDesigner MCP server

AI agents call caption_top to retrieve information from tdmcp — TouchDesigner MCP server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why caption_top is rated Low

The tool performs a read-only render operation on a TOP (Texture Operator) in TouchDesigner. It retrieves/renders visual data without modifying state or triggering side effects. While rendering has computational cost, it produces no persistent changes to the project or system. This is consistent with the Read category for data retrieval operations.

From the tool's definition Description explicitly states "Read-only: render a TOP"
