About SketchUp
SketchUp is an MCP server published by 1pitaph in the Files category: ruby plugin for SketchUp 3D modeling with geometry creation, entity transformation, material assignment, and model introspection via TCP bridge.
The repository has 7 stars and 0 forks, with the last commit 7 months ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

SU MCP Server
SketchUp MCP (Model Context Protocol) 服务器插件,使 AI 客户端(如 Claude)能通过标准化协议与 SketchUp 交互,实现 AI 辅助 3D 建模。
架构
MCP客户端 (Claude) <--stdio--> stdio_bridge.py <--TCP--> SketchUp TCP Server
- SketchUp 内部: 非阻塞 TCP 服务器 (端口 9876),使用
UI.start_timer轮询 - stdio_bridge.py: 跨平台 Python 脚本,桥接 stdio 和 TCP(无外部依赖)
- SketchUp 插件: 全部纯 Ruby 实现,无外部 gem 依赖
安装
-
将
su_mcp.rb和su_mcp/文件夹复制到 SketchUp 的 Plugins 目录:- Windows:
%APPDATA%\SketchUp\SketchUp 2024\SketchUp\Plugins\ - macOS:
~/Library/Application Support/SketchUp 2024/SketchUp/Plugins/
- Windows:
-
重启 SketchUp,在 Extension Manager 中确认 "SU MCP Server" 已启用
使用
启动服务器
- 菜单: Extensions > SU MCP Server > Start Server
- 或在 Ruby Console 中:
OnePitaph::SuMcp::PluginManager.start_server
配置 Claude Desktop
编辑 Claude Desktop 配置文件:
- Windows:
%APPDATA%\Claude\claude_desktop_config.json - macOS:
~/Library/Application Support/Claude/claude_desktop_config.json
Windows (需先将 stdio_bridge.py 复制到纯英文路径):
{
"mcpServers": {
"sketchup": {
"command": "python",
"args": ["C:\\su_mcp_bridge\\stdio_bridge.py"],
"env": { "SU_MCP_PORT": "9876" }
}
}
}
macOS:
{
"mcpServers": {
"sketchup": {
"command": "python3",
"args": ["/path/to/bridge/stdio_bridge.py"],
"env": { "SU_MCP_PORT": "9876" }
}
}
}
依赖: Python 3(macOS 内置;Windows 若无请从 python.org 安装并勾选 "Add Python to PATH")
配置保存后,完全重启 Claude Desktop 生效。
