Forge Fusion 360 MCP

Backwards intelligence for Autodesk Fusion 360 via Claude. Surface DFM constraints, certifications, manufacturer capabilities, and real costs — before your design starts.

What it does

Connect this MCP server to Claude Desktop alongside Anthropic's official Fusion 360 connector. Ask Claude:

• "Run a full Forge analysis before I design this enclosure"
• "Check injection molding DFM for this housing — 2mm ABS, IP67"
• "What's the cost impact of switching from ABS to PC-ABS at 5k units?"
• "Check sheet metal DFM for this bracket — 1.5mm steel"

Tools

| Tool | Description | |------|-------------| | analyze_product | Full backwards intelligence — certifications, DFM, costs, component risks, manufacturers | | check_injection_molding_dfm | DFM constraints for injection molded plastic parts | | check_sheet_metal_dfm | DFM constraints for sheet metal parts | | estimate_product_cost | Manufacturing cost at different volumes |

Setup

1. Install

npm install -g forge-fusion-mcp

2. Add to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "forge-fusion": {
      "command": "node",
      "args": ["/usr/local/lib/node_modules/forge-fusion-mcp/dist/index.js"],
      "env": {
        "FORGE_API_URL": "https://forge-rho-pink.vercel.app",
        "FORGE_API_KEY": "your_api_key"
      }
    }
  }
}

3. Restart Claude Desktop

4. Use alongside Anthropic's Fusion 360 connector

Add both MCPs — Anthropic's handles geometry creation, Forge handles intelligence.

Example

I'm designing an IP67 enclosure for a BLE sensor. 
ABS, two-part snap-fit, 120x80x40mm, 5k units/year, selling in US and EU.
Run a Forge analysis before I start modeling.
