WHAT IT DOES

What create_text_overlay does on tdmcp — TouchDesigner MCP server

AI agents use create_text_overlay 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_text_overlay is rated Medium

This tool creates or adds new data (a text overlay component) to a TouchDesigner project, which is reversible—the text element can be deleted or modified. It does not execute arbitrary code, delete data irreversibly, or trigger financial transactions. The modification is intentional and part of the normal workflow for building visual systems.

From the tool's definition Tool creates a 'Text TOP' component with configurable properties (font size, color, alignment) in TouchDesigner, which modifies the project state by adding a new visual element.

create_text_overlay Rate-limited

create_text_overlay 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.
