Common questions

Is 3D CAD Converter safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 33 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

3D CAD Converter MCP server

Lets an AI agent (Claude Code, Claude Desktop/Cowork, Codex, Cursor, VS Code and other MCP clients) use 3D CAD Converter on your Windows PC: converting STEP, IGES, STL, OBJ, FBX, glTF, 3MF and other 3D/CAD files.

3D CAD Converter is a Windows 10/11 desktop app with a free trial: https://www.contenta-software.com/3dcadconverter/download.php

How it works

This package is a small launcher. It finds 3D CAD Converter on your PC (cadconvert.exe, installed per-user in %LOCALAPPDATA%\Programs\CadConverter or on your PATH) and runs the app's own MCP server (cadconvert serve) over stdio. Tools: convert_cad, detect_format, get_file_info, list_formats, get_license_status.

If the app is not installed yet, the launcher serves a single get_started tool that gives your agent the download link and the install steps instead.

Full CLI and MCP reference: https://github.com/brunojanvier77/ContentaSoft/blob/main/cad-converter/mcp-server.md (MCP tools and their parameters) and https://github.com/brunojanvier77/ContentaSoft/blob/main/cad-converter/cli.md (the command line).

Add it to your client

Claude Code (Windows):

claude mcp add cad-converter -- cmd /c npx -y @contentasoft/cad-converter-mcp@1.0.5

Claude Desktop, Cursor and other clients that use mcpServers (JSON):

"mcpServers": { "cad-converter": { "command": "cmd", "args": ["/c", "npx", "-y", "@contentasoft/cad-converter-mcp@1.0.5"] } } }

VS Code (.vscode/mcp.json, note the servers key):

"servers": { "cad-converter": { "type": "stdio", "command": "cmd", "args": ["/c", "npx", "-y", "@contentasoft/cad-converter-mcp@1.0.5"] } } }

Codex (codex mcp add cad-converter -- cmd /c npx -y @contentasoft/cad-converter-mcp@1.0.5, or ~/.codex/config.toml):

[mcp_servers.cad-converter]

command = "cmd" args = ["/c", "npx", "-y", "@contentasoft/cad-converter-mcp@1.0.5"] startup_timeout_sec = 60 tool_timeout_sec = 3600

The first start downloads this small package, which can take longer than a client's default startup timeout (Codex: 10 s; Claude Code: set MCP_TIMEOUT); after that it starts at once. Long jobs such as video encodes can exceed a client's default tool timeout too (Codex: 60 s; Claude Code: MCP_TOOL_TIMEOUT). The app is told to stop a job when the client cancels it.

Once the app is installed you can also skip the launcher: "command": "cadconvert", "args": ["serve"].

What runs and what is sent

The launcher itself sends nothing over the network and writes nothing to disk. It starts cadconvert.exe.
The app works on local files on your PC. It sends anonymous usage telemetry (which tools ran, which MCP client connected, trial state) to ContentaSoft; turn it off in the app's settings. Privacy policy: https://www.contenta-software.com/3dcadconverter/privacy.php
The free trial has no end date: the first 10 conversions per PC come out at full quality (plus a newsletter bonus); after that STEP/IGES/BREP to a mesh is meshed at draft quality and every export carries a trial note. cadconvert status shows how many full-quality conversions are left. Nothing stops working; a licence removes the limits.

License

The launcher is MIT-licensed (see LICENSE). 3D CAD Converter itself is commercial software by ContentaSoft AB.
