3D CAD Converter — Claude Code MCP server: features and install
Bridges your coding assistant to the desktop 3D CAD Converter on Windows. Converts mechanical and 3D mesh files like STEP, STL, and glTF directly from prompts.
claude mcp add cad-converter -- npx -y @contentasoft/cad-converter-mcpWhat 3D CAD Converter does
This launcher runs the desktop application's internal MCP engine via stdio. It looks for cadconvert.exe in %LOCALAPPDATA%\Programs\CadConverter or your system PATH. Connected agents receive tools like convert_cad, detect_format, get_file_info, list_formats, and get_license_status. If the desktop executable is missing, the launcher serves only get_started with setup steps.
Operation requires Windows 10 or 11. Conversions fail if the desktop app is not on your machine. The trial provides 10 full-quality exports during the first 30 days. Afterwards, STEP, IGES, and BREP conversions drop to draft meshing with an added watermark. The desktop software collects anonymous telemetry, which you can disable inside its settings.
What it helps with
- convert STEP and IGES engineering files into STL or glTF meshes
- inspect 3D file formats and metadata directly in your editor
- batch prepare OBJ and 3MF assets for printing or rendering
Example prompts for the agent
- Convert mechanical_part.step to gltf format for web display
- Detect the file format of model.iges and inspect its geometry metadata
- Check 3D CAD Converter license status and list available export extensions

Questions about 3D CAD Converter
How to install 3D CAD Converter in Claude Code?
Run the following terminal command: claude mcp add cad-converter -- npx -y @contentasoft/cad-converter-mcp.
What does 3D CAD Converter do?
It lets your agent invoke a Windows desktop converter for 3D and CAD formats. You can inspect geometry, detect extensions, and translate files between STEP, STL, OBJ, and glTF.
Can this server run on macOS or Linux?
No, the backend executable cadconvert.exe runs exclusively on Windows 10 and 11. Non-Windows systems cannot launch the underlying conversion software.
