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.

English / 日本語

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

Please refer to the Installation Guide.

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.
`exec_node_method`	Calls a Python method on a node.
`execute_python_script`	Executes an arbitrary Python script in TouchDesigner.
`get_module_help`	Gets Python help() documentation for TouchDesigner modules/classes.
`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_node_errors`	Checks for errors on a specified node and its children.
`get_td_node_parameters`	Gets the parameters of a specific node.
`get_td_nodes`	Gets nodes under a parent path, with optional filtering.
`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 for errors on a specified node, and recursively for its children.

Resources

Not implemented.

Troubleshooting

Troubleshooting version compatibility

The MCP server uses semantic versioning for flexible compatibility checks

MCP Server	API Server	Minimum compatible API version	Behavior	Status	Notes
1.3.x	1.3.0	1.3.0	✅ Works normally	Compatible	Recommended baseline configuration
1.3.x	1.4.0	1.3.0	⚠️ Warning shown, continues	Warning	Older MCP MINOR with newer API may lack new features
1.4.0	1.3.x	1.3.0	⚠️ Warning shown, continues	Warning	Newer MCP MINOR may have additional features
1.3.2	1.3.1	1.3.2	❌ Execution stops	Error	API below minimum compatible version
2.0.0	1.x.x	N/A	❌ Execution stops	Error	Different MAJOR = breaking changes

Compatibility Rules:

✅ Compatible: Same MAJOR version AND API version ≥ 1.3.0 (minimum compatible version)
⚠️ Warning: Different MINOR or PATCH versions within the same MAJOR version (shows warning but continues execution)
❌ Error: Different MAJOR versions OR API server < 1.3.0 (execution stops immediately, update required)
To resolve compatibility errors:
1. Download the latest touchdesigner-mcp-td.zip from the releases page.
2. Delete the existing touchdesigner-mcp-td folder and replace it with the newly extracted contents.
3. Remove the old mcp_webserver_base component from your TouchDesigner project and import the .tox from the new folder.
4. Restart TouchDesigner and the AI agent running the MCP server (e.g., Claude Desktop).
For developers: When developing locally, run npm run version after editing package.json (or simply use npm version ...). This keeps the Python API (pyproject.toml + td/modules/utils/version.py), 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

TouchDesignerClient caches 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 from mcp_webserver_base.tox is running, and confirm the configured port (default 9981).
- 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. Use 127.0.0.1 unless 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 again—the client clears the cached error and re-verifies the connection automatically.
