TouchDesigner MCP

# TouchDesigner MCP Server Installation Guide Installation guide for TouchDesigner MCP across different AI agents and platforms. [English](installation.md) / [日本語](installation.ja.md) ## Quick Start Most users can get running quickly with the Claude Desktop bundle flow. Download both `touchdesigner-mcp-td.zip` and `touchdesigner-mcp.mcpb` from the [latest release](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest), import `mcp_webserver_base.tox` into your TouchDesigner project (`project1/mcp_webserver_base` is recommended), then double-click the `.mcpb` file to install it in Claude Desktop. The bundle automatically connects to TouchDesigner once the component is running. ## Table of Contents - [Prerequisites](#prerequisites) - [TouchDesigner Setup (Required for All Methods)](#touchdesigner-setup-required-for-all-methods) - [MCP Server Installation Methods](#mcp-server-installation-methods) - [Method 1: MCP Bundle (Claude Desktop only)](#method-1-mcp-bundle-claude-desktop-only) - [Method 2: NPM Package (Claude Code, Codex, and other MCP clients)](#method-2-npm-package-claude-code-codex-and-other-mcp-clients) - [Method 3: Docker Container](#method-3-docker-container) - [For Updates from Previous Versions](#for-updates-from-previous-versions) - [HTTP Transport Mode](#http-transport-mode) - [Verification](#verification) - [Troubleshooting](#troubleshooting) ## Prerequisites - **TouchDesigner** (latest version recommended) - For NPM-based installations: **Node.js** 18.x or later _(not required when you only use Claude Desktop with the MCP bundle)_ - For Docker-based installations: **Docker** and **Docker Compose** ## TouchDesigner Setup (Required for All Methods) **This step is required regardless of which installation method you choose.** 1. Download [touchdesigner-mcp-td.zip](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest/download/touchdesigner-mcp-td.zip) from the latest release 2. Extract the ZIP file 3. Import `mcp_webserver_base.tox` into your TouchDesigner project 4. Place it at `/project1/mcp_webserver_base` (or your preferred location) <https://github.com/user-attachments/assets/215fb343-6ed8-421c-b948-2f45fb819ff4> **⚠️ Most Important:** Do not change the folder structure or move files within the folder. `mcp_webserver_base.tox` references the contents of `modules/` using relative paths. **Directory Structure**: ```text touchdesigner-mcp-td/ ├── import_modules.py # Module loader ├── mcp_webserver_base.tox # Main component └── modules/ # Python modules ├── mcp/ # Core MCP logic ├── utils/ # Utilities └── td_server/ # API server code ``` You can verify successful setup by checking the Textport (Alt+T or Dialogs → Textport):  ## MCP Server Installation Methods Choose one of the following installation methods based on your AI agent and preferences. They all assume your TouchDesigner project already contains the imported `mcp_webserver_base.tox` component from the previous section. ### Method 1: MCP Bundle (Claude Desktop only) **Best for**: Claude Desktop users who want the simplest installation experience. #### Downloads Download the following from the [latest release](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest): - **TouchDesigner Components**: [touchdesigner-mcp-td.zip](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest/download/touchdesigner-mcp-td.zip) - **MCP Bundle**: [touchdesigner-mcp.mcpb](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest/download/touchdesigner-mcp.mcpb) #### Installation Steps 1. **Prepare TouchDesigner** - Complete the [TouchDesigner Setup](#touchdesigner-setup-required-for-all-methods) once per project (import `mcp_webserver_base.tox`, keep the folder layout intact, verify via Textport). 2. **Install the MCP Bundle** - Double-click the `touchdesigner-mcp.mcpb` file to install it in Claude Desktop <https://github.com/user-attachments/assets/0786d244-8b82-4387-bbe4-9da048212854> 3. **Start Using** - The bundle automatically handles the TouchDesigner server connection once the component is running - Restart Claude Desktop if the MCP server is not recognized - Open the Claude Desktop MCP panel to confirm that `touchdesigner-mcp` is available ### Method 2: NPM Package (Claude Code, Codex, and other MCP clients) **Best for**: Users who want flexibility across different AI agents or need custom configuration. #### Installation Prerequisites - Node.js 18.x or later installed - TouchDesigner components set up (see [TouchDesigner Setup](#touchdesigner-setup-required-for-all-methods)) Once those prerequisites are in place, add the MCP server to your client using one of the following configurations. #### For Claude Desktop Edit your `claude_desktop_config.json`: ```json { "mcpServers": { "touchdesigner": { "command": "npx", "args": ["-y", "touchdesigner-mcp-server@latest", "--stdio"] } } } ``` _Optional:_ Add `--host` / `--port` arguments if TouchDesigner is not running on the defaults (`http://127.0.0.1:9981`). #### For Claude Code Run the following command: ```bash claude mcp add -s user touchdesigner -- npx -y touchdesigner-mcp-server@latest --stdio ``` Or manually edit `~/.claude.json`: ```json { "mcpServers": { "touchdesigner": { "command": "npx", "args": ["-y", "touchdesigner-mcp-server@latest", "--stdio"], } } } ``` #### For Codex Run the following command: ```bash codex mcp add touchdesigner -- npx -y touchdesigner-mcp-server@latest --stdio ``` Or manually edit `~/.codex/config.toml`: ```toml [mcp_servers.touchdesigner] command = "npx" args = ["-y", "touchdesigner-mcp-server@latest", "--stdio"] ``` #### For Other MCP Clients Any MCP-compatible client can use the NPM package via stdio transport: - **Command**: `npx` - **Args**: `["-y", "touchdesigner-mcp-server@latest", "--stdio"]` - **Optional Args**: `--host=<url>`, `--port=<number>` Add the optional flags only when TouchDesigner is not running on `http://127.0.0.1:9981`. ### Method 3: Docker Container **Best for**: Developers, CI/CD pipelines, or users who prefer containerized environments. #### Docker Prerequisites - Docker and Docker Compose installed - TouchDesigner components set up (see [TouchDesigner Setup](#touchdesigner-setup-required-for-all-methods)) #### Installation Steps 1. **Clone the repository** ```bash git clone https://github.com/8beeeaaat/touchdesigner-mcp.git cd touchdesigner-mcp ``` 2. **Build the Docker image** ```bash make build ``` 3. **Start the container** Choose a transport configuration: ##### Option A: Streamable HTTP ([spec](https://modelcontextprotocol.io/specification/2025-11-25/basic/transports#streamable-http)) <https://github.com/user-attachments/assets/4025f9cd-b19c-42f0-8274-7609650abd34> 1. Start the container with HTTP transport: ```bash TRANSPORT=http docker-compose up -d ``` 2. (Optional) Override the HTTP port or TouchDesigner host: ```bash TRANSPORT=http \ MCP_HTTP_PORT=6280 \ TD_HOST=http://host.docker.internal \ docker compose up -d ``` 3. Point your MCP client to the HTTP endpoint. For example: - **Claude Code (native HTTP entry):** ```json { "mcpServers": { "touchdesigner-http": { "type": "http", "url": "http://localhost:6280/mcp" } } } ``` - **Claude Desktop (via `mcp-remote`):** ```json { "mcpServers": { "touchdesigner-http": { "command": "npx", "args": [ "mcp-remote", "http://localhost:6280/mcp" ] } } } ``` 4. Confirm the container is healthy (container binds `0.0.0.0`, Docker publishes to `127.0.0.1` by default): ```bash curl http://localhost:6280/health ``` ##### Option B: Stdio Passthrough 1. Start the container in stdio mode: ```bash docker-compose up -d ``` 2. Configure your client to exec into the container (Claude Desktop example): ```json { "mcpServers": { "touchdesigner-docker": { "command": "docker", "args": [ "compose", "-f", "/path/to/your/touchdesigner-mcp/docker-compose.yml", "exec", "-i", "touchdesigner-mcp-server", "node", "dist/cli.js", "--stdio", "--host=http://host.docker.internal" ] } } } ``` _On Windows include the drive letter (for example `C:\\path\\to\\touchdesigner-mcp\\docker-compose.yml`)._ ## For Updates from Previous Versions If you are updating, please refer to the procedure in the **[Latest Release](https://github.com/8beeeaaat/touchdesigner-mcp/releases/latest#for-updates-from-previous-versions)**. ## HTTP Transport Mode TouchDesigner MCP Server can run as an HTTP endpoint for remote clients, browser-based integrations, or when you prefer not to rely on stdio. Treat this section as optional—only follow it if you need HTTP/SSE access instead of stdio. You can start HTTP mode directly from the Node.js CLI or inside the Docker container. ### Starting in HTTP Mode #### Start the container with HTTP transport ```bash TRANSPORT=http docker-compose up -d ``` <https://github.com/user-attachments/assets/4025f9cd-b19c-42f0-8274-7609650abd34> #### Using npm command ```bash # Start HTTP server # 127.0.0.1:6280/mcp npm run http ``` <https://github.com/user-attachments/assets/5447e4da-eb5a-4ebd-bbbe-3ba347d1f6fb> ```bash touchdesigner-mcp-server \ --mcp-http-port=6280 \ --mcp-http-host=127.0.0.1 \ --host=http://127.0.0.1 \ --port=9981 ``` ### Configuration Options | Option | Description | Default | | --- | --- | --- | | `--mcp-http-port` | HTTP server port (required for HTTP mode) | - | | `--mcp-http-host` | Bind address (`0.0.0.0` in Docker entrypoint, `127.0.0.1` in CLI) | `127.0.0.1` (CLI) | | `--host` | TouchDesigner WebServer host | `http://127.0.0.1` | | `--port` | TouchDesigner WebServer port | `9981` | > Security tip (Docker): the container binds to `0.0.0.0`, but `docker-compose.yml` publishes `127.0.0.1:${MCP_HTTP_PORT}` by default so the endpoint is loopback-only. If you intentionally expose it to your LAN/WAN, change the compose port mapping (for example `"0.0.0.0:6280:6280"`) and protect it with a firewall/reverse proxy and authentication. ### Health Check ```bash curl http://localhost:6280/health ``` Expected response: ```json { "status": "ok", "sessions": 0, "timestamp": "2025-12-06T05:30:00.000Z" } ``` ### Transport Differences | Feature | stdio | Streamable HTTP | | --- | --- | --- | | Connection | Standard I/O | HTTP/SSE | | Use Case | Local CLI / desktop tools | Remote agents, browser integrations | | Session Management | Single connection | Multi-session with TTL | | Port Required | No | Yes | ## Verification After installation: 1. Start TouchDesigner with the imported `mcp_webserver_base.tox` component 2. Start your AI agent (Claude Desktop / Claude Code / Codex / etc.) 3. Confirm the `touchdesigner-mcp` server appears in the agent UI If it does not show up: - Restart the AI agent - Make sure TouchDesigner and the WebServer DAT are running - Review the logs for error messages Example view inside an agent:  ## Troubleshooting ### Version Compatibility Issues The MCP server enforces semantic versioning. If you see a compatibility warning or error: 1. Repeat the steps in [TouchDesigner Setup](#touchdesigner-setup-required-for-all-methods) 2. Remove the old `mcp_webserver_base` component and import the updated `.tox` 3. Restart both TouchDesigner and your AI agent See [Troubleshooting version compatibility](https://github.com/8beeeaaat/touchdesigner-mcp#troubleshooting-version-compatibility) in the README for additional details. ### Connection Issues Refer to [Troubleshooting connection errors](https://github.com/8beeeaaat/touchdesigner-mcp#troubleshooting-connection-errors) in the README for guided error messages (ECONNREFUSED, ETIMEDOUT, ENOTFOUND, etc.). ### Other Issues - Check [GitHub Issues](https://github.com/8beeeaaat/touchdesigner-mcp/issues) for known reports - Review the [main README](https://github.com/8beeeaaat/touchdesigner-mcp/blob/main/README.md) for more background information ## For Developer Setup Need developer-focused workflows?
