Kernelcad

Overview

Kernelcad is a Model Context Protocol (MCP) server: Agent-first CAD: editable .kcad.ts source, deterministic review, OpenCASCADE kernel. In practice that means any MCP-compatible AI assistant can call Kernelcad's tools directly — the model decides when to use them in a conversation or agent run.

You can run Kernelcad two ways: connect to the hosted endpoint at https://mcp.kernelcad.com/mcp with no local install, or run it on your own machine via the npm package kernelcad. The current release is v0.11.2, published under the MIT license, with source at w1ne/kernelCAD-web on GitHub, where it has earned 17 stars.

Kernelcad is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
