touchdesigner-mcp is a skill for Claude Code, Codex from davidtoby/agent-skills. It costs 38 tokens per session (4,143 once invoked), scanned A, a copy of touchdesigner-mcp, MIT.

A connection between an agent and a running TouchDesigner project, a tool for creating real-time interactive graphics. It can create and connect project components, change their settings, run Python, and inspect errors.

In plain words
What is it for?
Use it to build and modify real-time graphics, wire visual processing components, run project code, and troubleshoot TouchDesigner networks.
Why use it?
It lets an agent operate a live visual project through structured controls instead of manually editing every component.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

touchdesigner-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/setup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 "${HERMES_HOME:-$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
  5. Report what manual steps remain (drag .tox into TD, enable MCP toggle)

Manual steps (one-time, cannot be automated)

  1. Drag ~/Downloads/twozero.tox into the TD network editor → click Install
  2. Enable MCP: click twozero icon → Settings → mcp → "auto start MCP" → Yes
  3. Restart Hermes session to pick up the new MCP server

After setup, verify:

nc -z 127.0.0.1 40404 && echo "twozero MCP: READY"

Environment Notes

  • Non-Commercial TD caps resolution at 1280×1280. Use outputresolution = 'custom' and set width/height explicitly.
  • Codecs: prores (preferred on macOS) or mjpa as fallback. H.264/H.265/AV1 require a Commercial license.
  • Always call td_get_par_info before setting params — names vary by TD version (see CRITICAL RULES #1).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
