Overview of agentcad

1. What is agentcad?

agentcad is an open-source CAD tool designed specifically for AI agents, functioning as a Model Context Protocol (MCP) server and Command Line Interface (CLI). It enables coding agents like Claude Code, Cursor, and Windsurf to write build123d or CadQuery scripts, automatically validate geometry, catch broken code, and render models from multiple angles. This creates a tight feedback loop that helps AI agents fix their own design mistakes and converge on watertight, dimensionally correct, and printable 3D geometry without human intervention, ultimately exporting files in STEP, STL, GLB, and OBJ formats.

2. agentcad core features

agentcad has 6 core features, including:

1. Open-source MCP server and CLI for build123d and CadQuery scripts

2. Automated geometry validation catching errors in less than 100ms

3. Multi-angle PNG rendering for agent visual verification

4. Export support for STEP, STL, GLB, and OBJ formats

5. Topology reports and version diffs to track design iterations

6. Pre-injected build123d primitives removing the need for boilerplate imports

Give your coding agent the ability to design real, manufacturable parts. Hand Claude Code or Codex a prompt, a sketch, or image. It writes build123d or CadQuery scripts, then runs agentcad to check its own work, catching broken code, confirming the geometry is watertight and dimensionally correct, and rendering it from every angle so your agent fixes its mistakes before you ever see them. You get back an interactive viewer plus STEP / STL / GLB files — ready to inspect, edit, or print.

3. agentcad's use cases

There are many use cases for agentcad, including but not limited to the following:

1. Giving AI coding agents the ability to generate real, manufacturable 3D CAD parts from text prompts, sketches, or images
2. Automating the design and verification loop for complex mechanical parts like enclosures, mechanical components, and 3D printable objects
3. Building multi-part 3D reconstructions, such as the 1903 Wright Flyer, entirely through agentic AI loops
