How to Set Up and Use Houdini MCP

HoudiniMCP connects SideFX Houdini to Claude AI via the Model Context Protocol, enabling natural language control of Houdini's node-based 3D environment. It runs a local server inside Houdini that receives commands from Claude and translates them into node creation, scene modifications, and code execution within the application. Artists and technical directors use it to accelerate procedural scene setup, simulation configuration, and rendering workflows through conversational AI prompts.

Prerequisites

  • SideFX Houdini 19.5 or later installed on Windows or macOS
  • Python environment with uv package manager (https://astral.sh/uv)
  • MCP CLI installed via uv (uv add 'mcp[cli]')
  • Claude Desktop as the MCP client
  • Optional: RapidAPI account with OPUS subscription for procedural asset generation
1

Install uv on Windows

Install the uv Python package manager, which HoudiniMCP uses to manage its dependencies inside Houdini's Python environment.

powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
2

Install MCP dependencies inside the HoudiniMCP directory

Navigate to the houdinimcp scripts directory in your Houdini user folder and install the MCP CLI package.

cd C:/Users/<YourUserName>/Documents/houdini19.5/scripts/python/houdinimcp/
uv add "mcp[cli]"
3

Verify the MCP installation

Confirm MCP was installed correctly inside the Houdini Python environment.

uv run python -c "import mcp.server.fastmcp; print('MCP is installed!')"
4

Configure Claude Desktop

Add the HoudiniMCP server to your claude_desktop_config.json. The server runs the Python script using uv and listens on port 9876 by default.

5

Start the server from Houdini's shelf tool

Inside Houdini, use the HoudiniMCP shelf tool to toggle the server on. This starts a listener that Claude can send commands to. You should see a confirmation message in the Houdini console.

6

Optional: enable OPUS procedural assets

For furniture and environmental asset generation, copy urls.env.example to urls.env and add your RapidAPI key. Without this key the server still works — only OPUS tools are disabled.

cp urls.env.example urls.env
# Edit urls.env and add your RapidAPI key

Houdini MCP Examples

Client configuration

Add this to claude_desktop_config.json to connect Claude Desktop to HoudiniMCP. Adjust the path to match your Houdini version and username.

{
  "mcpServers": {
    "houdini": {
      "command": "uv",
      "args": [
        "run",
        "python",
        "C:/Users/<YourUserName>/Documents/houdini19.5/scripts/python/houdinimcp/houdini_mcp_server.py"
      ]
    }
  }
}

Prompts to try

Use these prompts inside Claude Desktop with Houdini running and the shelf tool server active.

- "Create a sphere with a mountain noise displacement in Houdini"
- "Set up a fluid simulation with a sphere emitter falling into a box"
- "Create a fractal tree using Houdini's L-system node"
- "Add a Mantra render node and set the output path to /tmp/render.exr"
- "Generate a procedural rock using VEX noise and add a principled shader"

Troubleshooting Houdini MCP

Claude Desktop cannot connect to the Houdini server

Make sure you have toggled the server ON using the HoudiniMCP shelf tool inside Houdini before trying to use Claude. The server listens on port 9876 — check that no firewall is blocking this port.

uv command not found when installing dependencies

After running the uv installer on Windows, you need to update your PATH. Run 'set Path=C:\Users\<YourUserName>\.local\bin;%Path%' in the current terminal session, then retry the uv add command.

OPUS tools are not available

OPUS asset generation requires a RapidAPI subscription. Copy urls.env.example to urls.env and add your RapidAPI key. Without the key, the server starts normally but OPUS-specific tools are disabled.
