Left: an engineering drawing of a flanged bushing — section A–A, the view from the left and the plan in first-angle projection, dimensioned, with a title block. Right: classcad·ai, or, the Art of Modelling with Agents — wherein a machine is taught to write parametric CAD models as programs, to draw what it has made, and to prove the work in numbers and in pixels. In five parts: the skill, the script, the renderer, the MCP server, the in-app agent. MMXXVI."></picture>

The MCP server takes requests from any agent host (Claude Code, Codex, OpenCode, Claude Desktop, VS Code, Cursor) through one daemon per machine: on its own, on a worker or its own WASM, it makes the part itself — a pointing hand leads to the flanged bushing, engraved in iso — or it joins any buerli app, by invite or over the bridge. The in-app assistant lives inside the app: asked to make a flanged bushing, it answers, and the part appears in the app’s window."></picture>
