What is Geop

Geop is a NURBS CAD tool built on an interval-arithmetic kernel, described by its author as open source. It supports MCP so AI agents can take part in modeling, and is available on the web and as a desktop download recommended for MCP use. Pricing and license details are not stated on the site.

How to use

1. Open app.geop-cad.dev to try Geop in your browser;
2. nothing to install and files stay in your browser.

7. Let an AI agent drive it over MCP:claude mcp add geop -- geop mcpfor Claude Code orcodex mcp add geop -- geop mcpfor Codex.

Use cases

• Parametric 3D part design in the browser with no install Letting Claude Code or Codex build CAD parts as JSON programs via CLI or MCP Importing and exporting STEP files with an exact NURBS kernel Building assemblies with robust booleans and named faces and edges that survive rebuilds Editing CAD parts inside VS Code
