How to Connect Claude AI to FreeCAD — Full MCP Setup Tutorial (It Actually Works!)

#ClaudeFable5 #FreeCAD #MCP Claude AI can now connect to FreeCAD — and in this FreeCAD tutorial, I show the complete FreeCAD MCP setup, step by step. By the end, you'll be doing AI CAD modeling in FreeCAD just by typing prompts: boxes, fillets, holes, parts from hand-drawn sketches, and even a mathematically generated spur gear, all ready for 3D printing. This is one of the most practical Claude Fable 5 use cases — text to CAD, from install to finished part. 📄 FREE PDF GUIDE (all commands & links): https://drive.google.com/file/d/1qVr3... ⏱️ TIMESTAMPS 00:00 Intro – How Claude + FreeCAD Connector Works 01:25 Step 1: Installing Claude Desktop 01:55 Step 2: Installing FreeCAD 02:50 Step 3: Installing UVX 05:02 Step 4: Installing the FreeCAD MCP Server 08:01 Configuring Claude Desktop to Connect to MCP 11:09 Starting the RPC Server & Connecting Claude 12:16 Testing the Connector: Creating a Test Part & Box 13:44 Adding a Fillet (Handling Ambiguous Prompts) 14:33 Adding Holes (Claude Reasons Through Placement) 15:49 Building a Part from a Hand-Drawn Sketch 17:10 Designing a Flange with Full Parameters 17:53 Important Tip: Save Your Work Before Closing 18:49 Building a Spur Gear from Scratch (No Gears Workbench) 19:38 Outro & What's Coming Next 🔗 LINKS FreeCAD: https://www.freecad.org FreeCAD MCP (by neka-nat): https://github.com/neka-nat/freecad-mcp Claude Desktop: https://claude.ai/download UV installation: https://docs.astral.sh/uv/getting-sta... ▶️ Previous video — What the FreeCAD connector can do: [link] In this CAD tutorial you'll learn the full Claude MCP setup: installing the FreeCAD MCP server, connecting it to Claude Desktop with UVX, editing the Claude config file, and using AI 3D modeling to build parametric parts with plain-language prompts — perfect for 3D printing, makers, engineers, product design, and anyone learning CAD in 2026.
