How to Set Up and Use Fusion 360
The Fusion 360 MCP Server connects AI coding agents like Claude to Autodesk Fusion 360 through a Python-based socket bridge and a custom Fusion add-in, exposing over 84 CAD and CAM tools via the Model Context Protocol. It enables natural language control of sketching, 3D feature creation, body operations, assembly, sheet metal, surfaces, CAM toolpaths, and G-code export—effectively turning Claude into a CAD automation co-pilot. Engineers and product designers use it to automate repetitive modeling tasks, generate parametric designs from descriptions, and run complex CAM setups without manually clicking through Fusion's UI.
Prerequisites
- Autodesk Fusion 360 installed and licensed on macOS or Windows
- Python 3.8+ and uv (Python package manager) installed
- Claude Code or another MCP-compatible client that supports stdio or socket connections
- The fusion360-mcp-server Python package (installable via uvx)
Install the Fusion 360 add-in
Copy the add-in files to Fusion 360's AddIns directory. On macOS use the install script; on Windows copy manually to the AppData path.
# macOS (using install script):
./scripts/install-addon.sh
# macOS (manual):
cp -r addon ~/Library/Application\ Support/Autodesk/Autodesk\ Fusion\ 360/API/AddIns/Fusion360MCP
# Windows (PowerShell):
Copy-Item -Recurse addon "$env:APPDATA\Autodesk\Autodesk Fusion 360\API\AddIns\Fusion360MCP"Activate the add-in in Fusion 360
Open Fusion 360, press Shift+S to open the Scripts and Add-Ins dialog, select the Fusion360MCP add-in, and click Run. The add-in starts a local socket server that the Python MCP server connects to.
Add the MCP server to Claude Code
Register the fusion360 MCP server using Claude Code's mcp add command. The server runs via uvx in socket mode, which connects to the running Fusion add-in.
claude mcp add fusion360 -- uvx fusion360-mcp-server --mode socketVerify connectivity with the ping tool
In Claude Code, call the ping tool to confirm the MCP server can communicate with the Fusion 360 add-in. A successful response returns {"pong": true}.
Start designing with natural language
With the add-in running and the MCP server connected, you can now issue CAD commands through Claude. Remember that all measurements must be in centimeters (Fusion's internal unit).

Example prompts for CAD automation through the Fusion 360 MCP server.
- "Create a 5cm x 3cm x 2cm box and fillet all top edges with a 0.2cm radius."
- "Sketch a circle with diameter 4cm on the XY plane, then extrude it 6cm to create a cylinder body."
- "Set up a CAM milling operation for the top face of the current body using a 0.6cm flat end mill."
- "List all bodies in the current design and rename the first one to 'housing'."
- "Create an assembly joint between component1 and component2 with a rigid joint type."Troubleshooting Fusion 360
ping tool returns an error or times out
Ensure the Fusion360MCP add-in is running inside Fusion 360 (Shift+S → Add-Ins → Fusion360MCP → Run). The socket server the add-in starts must be active before the Python MCP server can connect.
uvx command not found when adding the MCP server
Install uv, the Python package manager that provides uvx: 'curl -LsSf https://astral.sh/uv/install.sh | sh'. Then restart your terminal and retry.
Operations produce unexpected geometry or dimensions
All measurements in the Fusion 360 MCP server use centimeters, not millimeters or inches. Convert your dimensions before issuing commands. Each tool call performs a single operation—chain multiple prompts for complex models.
