### Description (declared)

# SketchUp MCP (hardened fork) 
 
Connect **SketchUp** to any MCP client (Claude Desktop, Claude Code, etc.) and 
drive it in natural language — create, transform and materialize geometry, run 
boolean operations, chamfer/fillet edges, build woodworking joints, and export 
the scene. 
 
## Provenance 
 
- Maintained by **[NeoNexAI Agency](https://github.com/NeoNexAI)** (AI 
  consulting studio). Contact: `info@neonexai.com`. 
- Hardened fork of [mhyrr/sketchup-mcp](https://github.com/mhyrr/sketchup-mcp), 
  itself inspired by [blender-mcp](https://github.com/ahujasid/blender-mcp). 
- **What "hardened" means:** the upstream project exposed an `eval_ruby` tool 
  (arbitrary Ruby execution inside SketchUp → full disk/network access). This 
  fork **removes it entirely** — Python server and Ruby extension — and the 
  extension socket listens **only on `127.0.0.1`**. The tool surface is 13 
  explicit, bounded tools. Audit the code yourself before installing, as you 
  would with any third-party software: the diff vs upstream is public. 
 
--- 
 
## Architecture (two pieces) 
 
SketchUp has no external API: it can only be driven from its **embedded Ruby 
API**. Hence two components working together: 
 
``` 
MCP client (Claude Desktop / Claude Code) 
        │  (MCP, stdio) 
        ▼ 
  MCP server (Python, this package — uvx) 
        │  (TCP socket 127.0.0.1:9876) 
        ▼ 
  SketchUp extension (Ruby, su_mcp/)  ──►  SketchUp 
``` 
 
## Requirements 
 
- **SketchUp** 2021 or later (Windows; the Ruby extension uses only the 
  standard SketchUp Ruby API). 
- **Python 3.10+** and **uv/uvx** (`pip install uv` or 
  `winget install astral-sh.uv`). 
 
## Installation 
 
### Step 1 — SketchUp extension (Ruby) 
 
Copy `su_mcp.rb` **and** the `su_mcp/` folder from this repository into: 
 
``` 
%AppData%\SketchUp\SketchUp 20XX\SketchUp\Plugins\ 
``` 
 
(replace `20XX` with your version). Restart SketchUp, then start the server: 
menu **Extensions → SketchUp MCP → Start Server…
