At a glance: Every major CAD platform now has MCP support. Blender MCP leads with 17.6k stars — one of the most popular MCP servers in existence. Rhino/Grasshopper has 5+ implementations. FreeCAD-MCP offers 57 tools with Docker headless execution. The glaring gap: actual interior design tools don't exist yet. Rating: 4/5.
Blender
ahujasid/blender-mcp (17,600+ stars)
blender-mcp (Python, 18+ tools). Two-way AI-Blender communication — object manipulation, material control, geometry nodes, asset libraries (Polyhaven/Sketchfab), Hyper3D model generation, viewport screenshots, and arbitrary Python execution. At 17.6k stars, this is one of the most popular MCP servers across all categories.
AutoCAD
- autocad-mcp (159 stars, Python, 8 tools) — freehand AutoLISP execution, 600+ ISA 5.1-2009 P&ID symbols, ezdxf headless backend (no AutoCAD needed)
- multiCAD-mcp (46 tools) — supports AutoCAD, ZWCAD, GstarCAD, BricsCAD with batch operations
- CAD-MCP, mcp-autocad-server — additional natural language CAD control options
FreeCAD
proximile/FreeCAD-MCP (57 tools)
FreeCAD-MCP — the highest tool count of any CAD MCP server. Docker headless execution, multi-AI support (Claude/GPT-4o/Gemini), TRELLIS.2 image-to-3D generation, Vision AI analysis, Gradio web interface, and Cloudflare tunnels.
Also: bonninr/freecad_mcp (direct Claude interaction), lucygoodchild/freecad-mcp-server (geometry/booleans), spkane/freecad-addon-robust-mcp-server (MCP Bridge Workbench), contextform/freecad-mcp.
SketchUp
sketchup-mcp (182 stars, Ruby/Python) — component manipulation, materials, scene inspection, Ruby code evaluation, and unique woodworking joinery tools (mortise/tenon, dovetail, finger joints).
Rhino & Grasshopper (5+ servers)
- rhinomcp (274 stars) — object manipulation, layer management, script execution, JSON TCP protocol
- GH_mcp_server — direct Rhino+Grasshopper interaction, GHPython generation
- rhino-grasshopper-mcp — ML-based automatic layout optimization
- grasshopper-mcp — component creation with high-level intent recognition
- rhino_mcp — prompt-assisted 3D modeling
Revit / BIM
revit-mcp (18 stars, C#/Python) — the only major BIM platform with MCP support. CRUD operations on Revit elements, plugin architecture, extensible command sets.
Fusion 360 & OpenSCAD
- Fusion-360-MCP-Server — thread-safe API, works with Claude/ChatGPT
- fusion360-mcp-server — script generation and execution
- openscad-mcp — multi-perspective rendering, animation, 300 tests, 80%+ coverage
What's Missing
No dedicated interior design servers (room layout, furniture placement, color palettes), no floor plan generators, no rendering engines (V-Ray, Lumion, Enscape), no landscape architecture, no building code compliance, no material catalogs (IKEA, Wayfair), no SolidWorks or Onshape.
Bottom Line
Outstanding CAD/3D tool coverage with strong community adoption — every major platform has MCP support and Blender alone has 17.6k stars. But the interior design workflow side (room layout, furniture, colors) is entirely missing.
