Overview
About This Skill
FreeCAD MCP integrates FreeCAD's CAD capabilities with Claude AI, allowing users to design 3D models through conversational commands. The skill supports PartDesign operations (pads, revolutions, fillets, chamfers, holes, patterns), Part primitives and boolean operations, and view controls including screenshots and zoom. Installation is cross-platform (Windows, macOS, Linux) with automatic setup via npm, and the MCP bridge server connects Claude directly to FreeCAD's API. Operations teams use it to streamline design workflows and reduce manual modeling effort, while designers and engineers benefit from rapid prototyping without learning complex CAD interfaces.
How to Use
Install with a single npm command (freecad-mcp-setup), which auto-detects your OS and FreeCAD installation. Launch FreeCAD, then open Claude Code or Claude Desktop and ask it to design objects—Claude will control FreeCAD in real-time. Verify connection by asking Claude to list available tools or check FreeCAD connectivity.
Use Cases
Create parametric 3D objects from text descriptions (boxes, cylinders, complex shapes)
Automate repetitive CAD operations like filleting, chamfering, and hole creation
Generate linear and circular patterns of features at specified intervals
Perform boolean operations (union, difference, intersection) on 3D bodies

Usage Examples
Prompt Template
I want to create a 3D model of a [SHAPE] for [COMPANY] in the [INDUSTRY] industry. The model should have [DIMENSIONS] and include [FEATURES]. Can you generate the FreeCAD Python script to create this model?
Example Output
# FreeCAD Python Script for 3D Model Creation
```python
import FreeCAD as App
import Part
# Create a new document
App.newDocument("Model")
# Create a cube with dimensions 100x50x20
cube = App.ActiveDocument.addObject("Part::Box", "Cube")
cube.Length = 100
cube.Width = 50
cube.Height = 20
# Add a cylindrical hole with diameter 20 and depth 20
hole = App.ActiveDocument.addObject("Part::Cylinder", "Hole")
hole.Radius = 10
hole.Height = 20
hole.Placement = App.Placement(App.Vector(50, 25, 0), App.Rotation())
# Cut the hole from the cube
App.ActiveDocument.addObject("Part::Cut", "Cut").Base = cube
App.ActiveDocument.Cut.Tool = hole
# Recompute the document
App.ActiveDocument.recompute()
```
This script creates a cube with dimensions 100x50x20 and adds a cylindrical hole with a diameter of 20mm in the center of one face. The hole has a depth of 20mm.Apply to these tools
