Autodesk Fusion

Autodesk Fusion MCP

MCP server for Autodesk Fusion: create, modify and inspect CAD geometry in a running Fusion session from any MCP client.

Registry name: com.autodesk.aps.api/fusion-local-mcp

How it works

This package is a thin bridge. The MCP server itself is built into the Fusion desktop application; the bundle proxies stdio to it over http://127.0.0.1:<port>/mcp (default port 27182) using mcp-remote. Everything stays on your machine.

This server requires Autodesk Fusion. If you don't already have it, download Fusion (www.autodesk.com) to get started.

Requirements

• Autodesk Fusion, installed and running. Without it there is nothing for the client to connect to.
• The MCP server enabled in Fusion (see Find your port and URL).
• An MCP client: Claude Desktop (MCPB bundle) or Cursor (manual config).

Find your port and URL

1. In Fusion, open Preferences > General > API.
2. Under "Preferences for Scripting and Programming", tick Fusion MCP Server (runs locally on this device).
3. Read Fusion MCP Server Port. The field label shows the full endpoint, by default http://127.0.0.1:27182/mcp.
4. Click Apply or OK. If you change the port, use the same value in your client.

Install

Claude Desktop

Download fusion_mcpb.mcpb from the Fusion MCP release and open it with Claude Desktop. The bundle asks for the port Fusion's MCP server listens on (default 27182).

Cursor

Open Settings > Cursor Settings > Tools & MCPs and add Fusion to your MCP configuration (~/.cursor/mcp.json, or .cursor/mcp.json in a project):

{  "mcpServers": {    "fusion": {      "url": "http://127.0.0.1:27182/mcp"    }  }}

Make sure the port matches the one shown in Fusion's preferences. See the Fusion blog post for more.
