How to Set Up and Use Autodesk Fusion
The Fusion MCP Server provides an MCP interface to Autodesk Fusion 360, exposing tools and resources from the Fusion API to AI clients like Claude and Cursor. It runs as a Python-based MCP server using HTTP SSE transport and communicates with Fusion 360's Python add-in via a local socket. The server exposes tools for creating sketches, displaying message boxes, and creating parameters, plus resources for reading the active document structure and user parameters — giving AI coding assistants a direct line into the 3D CAD environment.
Prerequisites
- Autodesk Fusion 360 installed with Python API access enabled
- Python available within Fusion 360's Python environment (for the add-in)
- An MCP client such as Claude Desktop or Cursor IDE
- Fusion 360's Python path (required to install mcp[cli] into Fusion's environment)
Install the MCP package into Fusion 360's Python environment
Run the provided installer script, or manually install mcp[cli] using Fusion 360's own Python executable. This is required because the add-in runs inside Fusion's sandboxed Python environment.
# Automated install:
python install_mcp_for_fusion.py
# Manual install (replace with your Fusion Python path):
"C:\Users\YourUser\AppData\Local\Autodesk\webdeploy\production\<version>\Python\python.exe" -m pip install "mcp[cli]"Clone the repository
Clone the fusion-mcp-server repository to your local machine to get the add-in and server files.
git clone https://github.com/Joe-Spencer/fusion-mcp-server
cd fusion-mcp-serverInstall the Fusion 360 add-in
Copy the add-in directory to Fusion 360's AddIns folder. Then open Fusion 360 > Tools > Add-Ins > Scripts and Add-Ins, find the add-in, and click Run.
# macOS:
cp -r fusion_addin ~/Library/Application\ Support/Autodesk/Autodesk\ Fusion\ 360/API/AddIns/
# Windows:
Copy-Item -Recurse fusion_addin "$env:APPDATA\Autodesk\Autodesk Fusion 360\API\AddIns\"Configure your MCP client to connect via SSE
The server exposes an HTTP SSE endpoint at http://127.0.0.1:3000/sse. Add this to your MCP client configuration. For Claude Desktop, use the sse transport type.
Open Fusion 360 and verify the connection
With both Fusion 360 running (add-in active) and your MCP client configured, ask Claude to display a message box in Fusion 360 to verify the end-to-end connection.
Autodesk Fusion Examples
Client configuration
Configure Claude Desktop to connect to the Fusion MCP server via HTTP SSE. The add-in must be running in Fusion 360 for the server to be available.
{
"mcpServers": {
"fusion": {
"type": "sse",
"url": "http://127.0.0.1:3000/sse"
}
}
}Prompts to try
Use these prompts to interact with Autodesk Fusion 360 through Claude. The server currently supports sketching, parameters, and document queries.
- "Show a message box in Fusion 360 saying 'Hello from Claude'"
- "Create a new sketch on the XY plane in Fusion 360"
- "Create a parameter called 'wall_thickness' with a value of 3mm"
- "What parameters are currently defined in the active Fusion 360 document?"
- "Read the structure of the current Fusion 360 design"Troubleshooting Autodesk Fusion
Connection refused when MCP client tries to reach http://127.0.0.1:3000/sse
The Fusion 360 add-in must be running to expose the SSE server. Open Fusion 360, go to Tools > Add-Ins > Scripts and Add-Ins, find the add-in, and confirm it shows as running. If it stopped, click Run again.
install_mcp_for_fusion.py fails or installs to the wrong Python
Fusion 360 uses its own bundled Python interpreter, not the system Python. Locate the Fusion Python executable in Autodesk's webdeploy directory and run pip install mcp[cli] using that specific executable path.
Tools appear in Claude but operations have no visible effect in Fusion 360
Ensure you have an active design open in Fusion 360 before sending commands. Some operations like create_new_sketch require an active document. Open or create a design in Fusion 360 first, then retry the command.
