MCP server for TouchDesigner - Control and operate TouchDesigner projects through AI agents
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent β or use 1-click editor setup below.
One-click editor setup isnβt available for this listing yet β we donβt have a confirmed install command, and weβd rather show nothing than point your editor at the wrong package or host. Follow the projectβs own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON βΎ
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself β its README, its docs, or a verified owner. We havenβt found those for touchdesigner-mcp-server, and weβd rather show nothing than a guess youβd paste into your client. Follow the projectβs own setup instructions for the current steps.

Documentation Overview
TouchDesigner MCP
This is an implementation of an MCP (Model Context Protocol) server for TouchDesigner. Its goal is to enable AI agents to control and operate TouchDesigner projects.
Overview
TouchDesigner MCP acts as a bridge between AI models and the TouchDesigner WebServer DAT, enabling AI agents to:
- Create, modify, and delete nodes
- Query node properties and project structure
- Programmatically control TouchDesigner via Python scripts
Installation
Tell the AI agent you already use:
That's it. The full procedure lives in the Installation Guide β it opens with a table matching each AI app to its route, and everyone starts from TouchDesigner Setup. Or follow it yourself, step by step.
If you are updating, please refer to the procedure in the Latest Release.
MCP Server Features
This server enables AI agents to perform operations in TouchDesigner using the Model Context Protocol (MCP).
Tools
Tools allow AI agents to perform actions in TouchDesigner.
| Tool Name | Description |
|---|---|
create_td_node | Creates a new node. |
delete_td_node | Deletes an existing node. |
describe_td_tools | Generates a manifest of the available TouchDesigner tools. |
exec_node_method | Calls a Python method on a node. |
execute_python_script | Executes an arbitrary Python script in TouchDesigner. |
get_td_class_details | Gets details of a TouchDesigner Python class or module. |
get_td_classes | Gets a list of TouchDesigner Python classes. |
get_td_info | Gets information about the TouchDesigner server environment. |
get_td_module_help | Gets Python help() documentation for TouchDesigner modules/classes. |
get_td_node_errors | Checks errors and warnings on a node and its descendants. Missing files, dangling references and shader failures are warnings, so no errors does not mean healthy. |
get_td_node_parameters | Gets the parameters of a specific node. |
get_td_nodes | Gets nodes under a parent path, with optional filtering. |
get_top_image | Captures the current output of a TOP node as an image. |
update_td_node_parameters | Updates the parameters of a specific node. |
Prompts
Prompts provide instructions for AI agents to perform specific actions in TouchDesigner.
| Prompt Name | Description |
|---|---|
Search node | Fuzzy searches for nodes and retrieves information based on name, family, or type. |
Node connection | Provides instructions to connect nodes within TouchDesigner. |
Check node errors | Checks errors and warnings on a specified node, and recursively for its descendants. |
Resources
Not implemented.

Troubleshooting
Troubleshooting version compatibility
The MCP server and the TouchDesigner component are versioned on two independent axes: the npm package version and the API version (the contract between the MCP server and the .tox component). Each release declares the API version it ships with (expectedApiVersion) and the minimum it supports (minApiVersion, currently 1.3.0). The connected component's API version is compared against those two values β the npm package version itself never gates compatibility, so updating the MCP server alone never invalidates a supported component.
| API Server (component) | Condition | Behavior | Status |
|---|---|---|---|
| = expected API version | Matches the shipped .tox | β Works silently | Compatible |
| β₯ minimum, < expected | Older component | β οΈ "Update Recommended" notice appended to responses, continues | Warning |
| > expected, same MAJOR | Newer component | β οΈ Warning to update the MCP server, continues | Warning |
| MAJOR above expected | Newer API generation | β Execution stops β update the MCP server | Error |
| < minimum (or missing) | Too old | β Execution stops β update the component | Error |
-
To resolve compatibility errors:
- Download the latest touchdesigner-mcp-td.zip from the releases page.
- Delete the existing
touchdesigner-mcp-tdfolder and replace it with the newly extracted contents. - Remove the old
mcp_webserver_basecomponent from your TouchDesigner project and import the.toxfrom the new folder. - Restart TouchDesigner and the AI agent running the MCP server (e.g., Claude Desktop).
-
For developers: When developing locally, run
npm run versionafter editingpackage.json(or simply usenpm version ...). This keeps the Python API (pyproject.toml+td/modules/utils/version.py),mcpCompatibility.expectedApiVersion, MCP bundle manifest, and registry metadata in sync so that the runtime compatibility check succeeds.
For a deeper look at how the MCP server enforces these rules, see Version Compatibility Verification.
Troubleshooting connection errors
TouchDesignerClientcaches failed connection checks for 60 seconds. Subsequent tool calls reuse the cached error to avoid spamming TouchDesigner and automatically retry after the TTL expires.- When the MCP server cannot reach TouchDesigner, you now get guided error messages with concrete fixes:
ECONNREFUSED/ "connect refused": start TouchDesigner, ensure the WebServer DAT frommcp_webserver_base.toxis running, and confirm the configured port (default9981).ETIMEDOUT/ "timeout": TouchDesigner is responding slowly or the network is blocked. Restart TouchDesigner/WebServer DAT or check your network connection.ENOTFOUND/getaddrinfo: the host name is invalid. Use127.0.0.1unless you explicitly changed it.
- The structured error text is also logged through
ILogger, so you can check the MCP logs to understand why a request stopped before hitting TouchDesigner. - Once the underlying issue is fixed, simply run the tool againβthe client clears the cached error and re-verifies the connection automatically.
