Fusion360

You can use this MCP server to connect AI coding agents to Autodesk Fusion 360 for CAD automation. It acts as a bridge that lets MCP-compatible clients send commands to Fusion 360, enabling automated design, modification, and analysis tasks from AI agents while the actual API calls run safely on Fusion's main thread.

How to use

This MCP server lets you connect an MCP-compatible client (such as Claude Code, OpenCode, Codex, Cursor, or any client speaking the Model Context Protocol) to Autodesk Fusion 360. The server runs as a local process and communicates with Fusion through a dedicated add-in that executes API calls on Fusion's main thread. To use it, install the Fusion 360 add-in, start the add-in, then launch your MCP client configured to talk to the local server. Verify connectivity with a quick ping from your client.

Typical end-to-end flow:

• Install and enable the Fusion360MCP add-in inside Fusion 360.
• Start the add-in and confirm the server is listening on localhost:9876.
• Run your MCP client with the provided command to start the local MCP server bridge.
• Use a simple health check (ping) to confirm the connection is live.

How to install

Follow these concrete steps to set up the Fusion360 MCP Server and connect an MCP client.

Prerequisites you need to have installed first.

Step 1: Install the Fusion 360 Add-in

• You can download the latest add-in from Releases, or clone the repository and copy the Fusion360MCP/ directory into Fusion's AddIns folder.

macOS example command: cp -r Fusion360MCP ~/Library/Application\ Support/Autodesk/Autodesk\ Fusion\ 360/API/AddIns/

Windows example (PowerShell): Copy-Item -Recurse Fusion360MCP "$env:APPDATA\Autodesk\Autodesk Fusion 360\API\AddIns\" After copying, start the add-in in Fusion: Shift+S → Add-Ins → Fusion360MCP → Run. You should see a status message indicating the server is listening on localhost:9876 in the TEXT COMMANDS window.

Step 2: Connect your MCP client

• The MCP server is published on PyPI, so you can run it without cloning. Use the stdio-based command below with your MCP client.

Claude Code (example):

claude mcp add fusion360 -- uvx fusion360-mcp-server --mode socket

Other MCP clients: the server runs over stdio, so you can start it with:

uvx fusion360-mcp-server --mode socket

Cursor example configuration (JSON):

{ "mcpServers": { "fusion360": { "command": "uvx", "args": [ "fusion360-mcp-server", "--mode", "socket" ] } } }

Step 3: Verify the connection

• From your MCP client, run a ping tool against the server. A successful response should be something like {"pong": true} indicating the bridge is connected.

## Additional notes

Uninstalling or stopping the setup is straightforward. Remove the Fusion360MCP add-in from Fusion's AddIns directory, stop the add-in via the Fusion interface (Shift+S → Add-Ins → Fusion360MCP → Stop), and delete the add-in folder.

Operational considerations:
- All Fusion API calls operate in centimeters (Fusion’s internal unit).
- Execute one operation per tool call; batching multiple operations can cause the add-in to crash.
- Each command has a 30-second timeout, after which the operation will fail and return an error.
- The add-in writes logs to the user’s home directory under fusion360mcp.log for troubleshooting.
