# tdmcp — TouchDesigner MCP server

tdmcp lets an AI assistant build TouchDesigner node networks from plain-language requests, check them, and return a preview. Use it to turn a visual idea into a working project network.

## What it does

tdmcp connects an AI assistant to a TouchDesigner project. Its server supplies tools and embedded reference material on operators, Python classes, workflows, and GLSL. A bridge running inside TouchDesigner creates and links nodes; the server then checks the network and produces a preview. Generated layouts are arranged from left to right.

You need TouchDesigner and an MCP-capable assistant. Run the server with `npx -y @dpantani/tdmcp`, then enable the bridge in TouchDesigner, for instance by dropping `tdmcp_bridge_package.tox` into `/project1` and clicking **Install**. The bridge must be running for the assistant to control the project. Building from source requires Node.js 20+.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `TDMCP_TOOL_PROFILE`, `TDMCP_RAW_PYTHON` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- build a TouchDesigner node network from a written description
- check a generated network for errors
- preview a visual system in the project
- create and connect nodes in `/project1`

## Example prompts
- Build a noise-based feedback tunnel in TouchDesigner, add blur and displacement, then send it to a window with bloom.
- Add a feedback trail to the visual and send it fullscreen.
