WHAT IT DOES

What create_ascii_render does on tdmcp — TouchDesigner MCP server

AI agents use create_ascii_render 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_ascii_render is rated Medium

This tool modifies the TouchDesigner project by creating new operators and containers, which constitutes a Write operation (reversible creation of data/components). While it performs rendering operations on visual data, the primary effect is to create and add new nodes to the project network. The changes are reversible (components can be deleted), so it does not reach Destructive severity.

From the tool's definition Tool creates new components and operators in TouchDesigner: 'Creates a resolutionTOP (cells), textTOP (atlas), glslTOP, and nullTOP output inside a new baseCOMP.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_ascii_render 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_ascii_render, this is the rule to start with:

create_ascii_render Rate-limited

create_ascii_render 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.

Supports mono, source-color (per-cell tint), and two-color (lerp by luminance) modes. Phosphor-green default for the Severance / CRT terminal look. Creates a resolutionTOP (cells), textTOP (atlas), glslTOP, and nullTOP output inside a new baseCOMP. Exposes Mix, CellSize, and Charset controls.
