text-to-model

Turn natural language into 3D models in Fusion 360.

An MCP (Model Context Protocol) server add-in that connects Claude to Autodesk Fusion 360 — giving you 64 CAD tools controllable through plain text.

---

• Natural Language → CAD — Describe what you want, Claude builds it in Fusion 360
• 64 MCP Tools — Sketches, extrudes, fillets, sweeps, lofts, booleans, patterns, and more
• JIS Standard Parts — Generate bolts, nuts, screws, washers, keyways, bearings, and O-rings with accurate JIS dimensions (ISO equivalents planned)
• Full Parametric Workflow — Sketches → features → modifications → export (STEP/STL)
• Works with Claude Desktop & Claude Code

• Autodesk Fusion 360
• Claude Desktop or Claude Code
• Node.js (for npx)

1. Clone this repo into Fusion 360's add-in directory:

# Windows
git clone https://github.com/mikan-atomoki/text-to-model.git "%APPDATA%\Autodesk\Autodesk Fusion 360\API\AddIns\TextToModel"

# macOS
git clone https://github.com/mikan-atomoki/text-to-model.git ~/Library/Application\ Support/Autodesk/Autodesk\ Fusion\ 360/API/AddIns/TextToModel

1. In Fusion 360: UTILITIES → ADD-INS → Scripts and Add-Ins → Run TextToModel

1. Connect to Claude:

Claude Desktop — add to your MCP config (claude_desktop_config.json):

{
  "mcpServers": {
    "fusion360": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://127.0.0.1:13405/sse"]
    }
  }
}

Claude Code — run:

claude mcp add fusion360-mcp --transport sse http://127.0.0.1:13405/sse

That's it. Open Claude and start modeling.
