# TouchDesigner Integration (twozero MCP)

## CRITICAL RULES

1. **NEVER guess parameter names.** Call `td_get_par_info` for the op type FIRST. Your training data is wrong for TD 2025.32.
2. **If `tdAttributeError` fires, STOP.** Call `td_get_operator_info` on the failing node before continuing.
3. **NEVER hardcode absolute paths** in script callbacks. Use `me.parent()` / `scriptOp.parent()`.
4. **Prefer native MCP tools over td_execute_python.** Use `td_create_operator`, `td_set_operator_pars`, `td_get_errors` etc. Only fall back to `td_execute_python` for complex multi-step logic.
5. **Call `td_get_hints` before building.** It returns patterns specific to the op type you're working with.

## Architecture

```
Hermes Agent -> MCP (Streamable HTTP) -> twozero.tox (port 40404) -> TD Python
```

36 native tools. Free plugin (no payment/license — confirmed April 2026).
Context-aware (knows selected OP, current network).
Hub health check: `GET http://localhost:40404/mcp` returns JSON with instance PID, project name, TD version.

## Setup (Automated)

Run the setup script to handle everything:

```bash
bash "${HERMES_HOME:-$HOME/.hermes}/skills/creative/touchdesigner-mcp/scripts/setup.sh"
```

The script will:
1. Check if TD is running
2. Download twozero.tox if not already cached
3. Add `twozero_td` MCP server to Hermes config (if missing)
4. Test the MCP connection on port 40404
