sketchup-mcp-bridge
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| SKETCHUP_MCP_HOST | No | Host where SketchUp is running | localhost |
| SKETCHUP_MCP_PORT | No | TCP port the Ruby server listens on | 9876 |
| SKETCHUP_MCP_SCREENSHOT_DIR | No | WSL path to a host-side temp dir (e.g. /mnt/c/Users/<you>/AppData/Local/Temp); the screenshot tool raises an error if unset |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

TDQS
Scored across 4 tools
Each tool serves a clearly distinct purpose: eval_ruby executes arbitrary code, get_scene_info returns model metadata, get_selection returns selected entities, and screenshot captures the viewport. There is no overlap or ambiguity in when to use each tool.
Three tools use a verb_noun pattern (eval_ruby, get_scene_info, get_selection), but 'screenshot' is a single noun-verb hybrid that breaks the pattern slightly. The set is still mostly predictable and readable.
Four tools is a lean, well-scoped set for a bridge server. Each tool earns its place: one general execution tool plus three focused observation helpers.
The eval_ruby escape hatch allows arbitrary model modifications, so most SketchUp operations are reachable. However, the lack of structured write/update/delete tools for specific entity types means agents must rely on raw Ruby rather than dedicated operations.
