SketchupMCP

SketchupMCP connects Sketchup to Claude AI through the Model Context Protocol (MCP), allowing Claude to directly interact with and control Sketchup. This integration enables prompt-assisted 3D modeling, scene creation, and manipulation in Sketchup.

Big Shoutout to Blender MCP for the inspiration and structure.

Features

• Two-way communication: Connect Claude AI to Sketchup through a TCP socket connection
• Component manipulation: Create, modify, delete, and transform components in Sketchup
• Material control: Apply and modify materials and colors
• Scene inspection: Get detailed information about the current Sketchup scene
• Selection handling: Get and manipulate selected components
• Ruby code evaluation: Execute arbitrary Ruby code directly in SketchUp for advanced operations

Components

The system consists of two main components:

1. Sketchup Extension: A Sketchup extension that creates a TCP server within Sketchup to receive and execute commands
2. MCP Server (sketchup_mcp/server.py): A Python server that implements the Model Context Protocol and connects to the Sketchup extension

Installation

Python Packaging

We're using uv so you'll need to brew install uv

Sketchup Extension

1. Download or build the latest .rbz file
2. In Sketchup, go to Window > Extension Manager
3. Click "Install Extension" and select the downloaded .rbz file
4. Restart Sketchup

Usage

Starting the Connection

1. In Sketchup, go to Extensions > SketchupMCP > Start Server
2. The server will start on the default port (9876)
3. Make sure the MCP server is running in your terminal

Using with Claude

Configure Claude to use the MCP server by adding the following to your Claude configuration:

    "mcpServers": {
        "sketchup": {
            "command": "uvx",
            "args": [
                "sketchup-mcp"
            ]
        }
    }

This will pull the latest from PyPI

Once connected, Claude can interact with Sketchup using the following capabilities:

Tools

• get_scene_info - Gets information about the current Sketchup scene
• get_selected_components - Gets information about currently selected components
• create_component - Create a new component with specified parameters
• delete_component - Remove a component from the scene
• transform_component - Move, rotate, or scale a component
• set_material - Apply materials to components
• export_scene - Export the current scene to various formats
• eval_ruby - Execute arbitrary Ruby code in SketchUp for advanced operations

Example Commands

Here are some examples of what you can ask Claude to do:

• "Create a simple house model with a roof and windows"
• "Select all components and get their information"
• "Make the selected component red"
• "Move the selected component 10 units up"
• "Export the current scene as a 3D model"
• "Create a complex arts and crafts cabinet using Ruby code"

Troubleshooting

• Connection issues: Make sure both the Sketchup extension server and the MCP server are running
• Command failures: Check the Ruby Console in Sketchup for error messages
• Timeout errors: Try simplifying your requests or breaking them into smaller steps

Technical Details

Communication Protocol

The system uses a simple JSON-based protocol over TCP sockets:

• Commands are sent as JSON objects with a type and optional params
• Responses are JSON objects with a status and result or message
