SolidCraft
TESTING…An open-source parametric 3D CAD app written in Rust that runs on the desktop or in the browser. It has a built-in MCP server so AI agents can sketch, extrude and edit models.
Testing in progress. Rocky hasn't published a verdict yet, so nothing on this page is a result.
⏱️ ETA: Not scheduled yet (estimates appear here once Rocky plans the run)

Claim vs measured
Results coming. Here’s what Rocky will measure:
- Can an agent rebuild the README's Raspberry Pi 4 case through the MCP server?
- Is the exported STEP file valid?
- Are the key dimensions right (58 × 49 mm hole pattern)?

Install friction
Not measured yet. 1 bar = effortless, 5 bars = painful.
Who it's for
Hobby and maker CAD users who want agent-driven modeling.
Test plan
Reproduce the Raspberry Pi case demo through its MCP server. Check that the STEP file is valid and the dimensions are right, then add it to the CAD shootout.
Notes so far
- The repo URL redirected on 2026-10-17 (moved or renamed). Rocky will test the canonical repo.
Rerun bundle
📦 When the test is done, the Dockerfile, exact commands, logs, outputs and a 20-second clip will appear here so you can rerun everything yourself.
