제작자가 쓴 설명(영어 원문)
CAD in ChatGPT and Claude: editable parts, STEP/STL/drawings, in-chat 3D, automatic checks.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.
쓰고 있는 AI 앱을 고른 다음 설정을 복사하세요.

어떤 앱을 쓰세요?
위에서 앱을 고르세요. 기억해 두었다가 다음부터는 버튼에 “…에 설치”라고 표시해요.
웹, 데스크톱, 모바일의 Claude에서 쓸 수 있어요:

ChatGPT는 인터넷에 있는 서버에만 연결할 수 있어요:

선택한 앱은 이 기기의 쿠키에만 저장돼요. 계정은 필요 없어요.
이 설정은 제작자의 레지스트리 정보로 만들었어요. README와 다르면 README를 따르세요.
아직 이 서버의 도구 목록을 읽지 않았어요. 엔드포인트는 차례대로 돌아가며 점검해요.

레지스트리에서 이 카테고리의 활성 서버 전체와 비교했어요. 스타는 게시자가 저장소를 소유한 경우에만 세요.
해당하는 기본 점검 1개 중 1개를 통과했어요. 코드는 읽지 않았어요. 키나 토큰을 넣기 전에 서버가 어떤 권한을 요구하는지 확인하고, 꼭 필요한 권한만 있는 키를 쓰세요.
레지스트리에 필수 키가 나와 있지 않아요. 다만 처음 쓸 때 로그인을 요구하는 서버도 있어요.
제작자의 클라우드에서 실행돼요. 설치 없이 인터넷으로 연결하지만, 보내는 내용은 제작자의 서버를 거쳐요.
GitHub 저장소는 마지막으로 – 변경됐고, 최신 버전(0.17.1)은 10일 전 레지스트리에 올라왔어요.
Claude Desktop, Claude Code, Cursor, VS Code처럼 MCP를 지원하는 앱에서 쓸 수 있어요. URL로 연결되기 때문에, 원격 MCP 서버를 지원하는 앱(예: 개발자 모드의 ChatGPT)에서도 쓸 수 있어요.

Describe a mechanical part in ChatGPT, Claude, Codex, Cursor, or the browser. kernelCAD turns the brief into editable parametric CAD, lets you inspect and revise the geometry, and exports STEP, STL, and drawings.
Start here: Open Studio · Connect your agent · Watch real tool workflows · Read the prompt-to-STEP guide
Why not just generate an image? Your design remains .kcad.ts source: named features, editable dimensions and assembly structure. Agents can evaluate it, check constraints and clearances, revise the source, and export files for an engineer to inspect. Reproducible example source and documented checks are public. Geometry checks are not material-strength or manufacturing certification.
Connect a hosted MCP client: https://mcp.kernelcad.com/mcp (no local CAD install). Run locally: npx -y kernelcad mcp (Node.js 22.12+).
Source scope: this repository contains the reusable CAD runtime, CLI, MCP
tools and headless renderer. Hosted UI and commercial services are maintained
separately. Build the reusable tools with
npm run build; usenpm run dev
for the standalone renderer.
The workflow is: brief → editable .kcad.ts → evaluated B-rep → validation → guided revision → STEP/STL/drawing. OpenCASCADE is the geometry kernel; kernelCAD supplies the agent-first modeling and review workflow.
Describe a part, refine its editable CAD source, and export the geometry or drawing needed for the next step. These examples are starting points for designing parts for different processes:
| Process | Example | Reusable CAD reference |
|---|---|---|
| 3D printing | An electronics enclosure with locating lid and PCB posts | Enclosure |
| CNC milling | A bearing block with mounting holes and a stepped seat | Bearing block |
| Sheet metal | A four-hole bent bracket with a flat pattern | Bent bracket |
| Laser or waterjet cutting | A motor mounting plate with pilot and hole patterns | Motor plate |
| Turning | A shouldered spacer with an axial bore | Shoulder spacer |
| Assemblies | A bearing, housing, shaft and retainer | Bearing assembly |
| Injection molding | A drafted housing with board-screw bosses and structural ribs | Moulded housing |
The output is CAD for review, not a manufacturing certification. Check dimensions, fit, material and process requirements, and prototype or obtain engineering review as appropriate for the part. The case notes describe what has been checked and what remains open for each model.
kernelCAD runs as a connected app in ChatGPT (Apps SDK, with the Studio viewer and paint review inside the chat) and in Claude / claude.ai (custom connector). Add it from the chat settings and sign in:
https://mcp.kernelcad.com/mcpOne account everywhere. The coding-agent plugins below use the same hosted server (https://mcp.kernelcad.com/mcp) and the same kernelCAD sign-in. A model saved from Claude Code, Codex, Cursor, Gemini or Grok opens at the same Studio share link (/p/ ) you see in ChatGPT or Claude. Sign in with the same account in each client.
Ask your agent: “look at kernelcad.com and install the mcp”. Agent-readable installation instructions cover hosted setup, local CLI setup, and connection verification.
Run the MCP server over stdio with no install (Node.js 22.12 or newer):
npx -y kernelcad mcp
Claude Code: claude mcp add kernelcad -- npx -y kernelcad mcp
To keep the kernelcad command on your PATH:
npm install --global kernelcad
For a self-contained install that includes Node.js, Linux and macOS users can run:
curl -fsSL https://kernelcad.com/install.sh | sh
On Windows PowerShell, run:
irm https://kernelcad.com/install.ps1 | iex
The direct installers download a platform archive, verify its SHA-256 checksum, and install it under the user's home directory. Pin a release with KERNELCAD_VERSION=vX.Y.Z on Linux/macOS or $env:KERNELCAD_VERSION='vX.Y.Z' in PowerShell. Builds are available for Linux x64/ARM64, macOS Intel/Apple Silicon, and Windows x64. Direct installs do not require a separately installed Node.js.
For regulated or air-gapped machines, kernelcad --sandbox … and kernelcad mcp --sandbox --workspace (or KERNELCAD_SANDBOX=1) keep all file access inside one workspace directory and refuse outbound network at runtime, including telemetry. See docs/sandbox.md.
One command connects your agent to the hosted kernelCAD MCP server (https://mcp.kernelcad.com/mcp) and adds the kernelCAD skills. Nothing runs locally and no OpenCASCADE install is needed. Anonymous use works; sign in through your client's OAuth prompt for account features.
| Agent | One-liner |
|---|---|
| Claude Code | claude plugin install kernelcad --marketplace w1ne/kernelCAD-web |
| Codex | codex plugin marketplace add w1ne/kernelCAD-web && codex plugin add kernelcad@kernelcad |
| Cursor | Add kernelCAD MCP to Cursor (MCP only) |
| Gemini CLI | gemini extensions install https://github.com/w1ne/kernelCAD-web --consent --auto-update |
| Grok Build | grok plugin marketplace add w1ne/kernelCAD-web && grok plugin install kernelcad --trust |
| VS Code / Copilot | code --add-mcp '{"name":"kernelcad","type":"http","url":"https://mcp.kernelcad.com/mcp"}' |
| Skills only (any agent) | npx skills add w1ne/kernelCAD-web |
Inside Claude Code you can also type /plugin marketplace add w1ne/kernelCAD-web then /plugin install kernelcad@kernelcad. Restart the app after installing. Claude Desktop, ChatGPT, Windsurf, Cline, Zed, Continue, update, uninstall and the Cursor skills install are in docs/usage/agent-plugin-install.md.
Each model below started from the plain-language prompt shown. An AI agent wrote it through kernelCAD's own authoring loop (CLI / MCP): it wrote .kcad.ts source, ran evaluate, rendered the seven-view inspection sheet, read the renders, fixed what was wrong, and repeated. None of these is a one-shot generation. Each folder in showcase/ holds the parametric source, the turntable GIF (kernelcad animate --turntable, publish look), and a short note on what to look at and which checks were run.

Some checks go past the picture:
evaluate_script → mechanism: "real") turns each mechanism through its limits with the couplings applied and looks for overlapping teeth. kernelcad validate --include-interference reports both assemblies clean.kernelcad dfm passes it (thinnest wall 2.0 mm, no unsupported overhang), and kernelcad export step writes a B-rep whose holes read back with kernelcad inspect step..kcad.ts, CLI, and MCP. The UI reviews and steers generated designs.The headless OCCT gate checks 27 native .kcad.ts reference parts against analytic or recorded OCCT volume, surface-area, and bounding-box values. The current headline is 27/27 reference parts match; the expected-pass gate is 27/27, with the analytic inputs and tolerances listed in the scorecard. See the reference-parts scorecard and its local validation demo.
