CAD with a real MCP server, not a screenshot loop

Run `solidcraft-cli mcp` and an agent gets the same commands a person uses in the app: sketch, constrain, extrude, measure volume, area and center of mass, take screenshots to check its work, and export the file. Since 0.13 there is also an agent chat inside the app where Claude Code, Codex, OpenCode and others plug in with their own logins, every answer can be undone in one step and file actions ask first. Version 0.15 (October 17) added sweeps along guide rails, cam and follower joints, motion analysis with collision checks and GIF export. A community rover model (SELENE) was built in 3,323 MCP steps that all rebuild without errors. The team calls it early and best for simple parts for now, installers are not code-signed yet, and 0.15 files do not open in 0.14. About 5,800 GitHub stars in under two weeks.
