agentcad

Open-source MCP server that lets AI agents design real, printable CAD

Verified geometry feedback loop

Every run returns dimensions, volume, face/edge counts, and an is_valid flag plus PNG renders so the agent can iterate until the part is genuinely printable.

build123d-native, CadQuery-compatible

Scripts are written with the build123d API and pre-injected primitives, while CadQuery-compatible workflows are supported for existing projects.

Multi-format export

Produce versioned STEP files for CAD interchange and STL, GLB, or OBJ for 3D printing and web viewers.

Validation, inspection, and diffing

Pre-execution checks catch errors before running, a topology report helps debug geometry issues, and version diffs track design iteration.

Strengths & Pros

+Free and open source under Apache-2.0 with no signup required
+Returns metrics and renders so agents catch bad geometry before you do
+Runs locally with a small, zero-boilerplate scripting surface
+Works with Claude Code, Cursor, Windsurf, and any MCP-compatible agent via uvx

Best Alternatives to agentcad & Spline (12)

Limitations

–Requires Python 3.10–3.12 and comfort with script-based parametric modeling
–Best results depend on an agent that can read metrics and iterate
–It complements rather than replaces a full GUI CAD application for manual edits

Spline

Browser-based 3D design and animation with real-time team and AI agent collaboration

In-browser 3D editor

Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.

Materials, lighting and post-processing

Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.

Animation and interaction

Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.

Agent collaboration over MCP

Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.

Strengths & Pros

+Runs entirely in the browser, so there is no heavy install or setup barrier
+Real-time collaboration and agent workflows keep designers and developers in one shared file
+One scene publishes to web, iOS and Android with platform-native renderers
+Broad feature set spanning modeling, materials, animation, physics and interaction

Limitations

–Advanced 3D work may still require a learning curve for newcomers
–Performance and export options depend on the device and platform you target
–Team and enterprise capabilities sit behind paid tiers
