A browser 3D CAD for your AI: it scripts real-size models, uCAD builds them and returns pictures.
uCAD is a browser 3D CAD service: the assistant writes scripts in its small Python language, uCAD builds real-size models and returns reports and pictures.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/app.ucad%2Fucad/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}uCAD script language
Call this FIRST in every session, before writing any uCAD script, even if you have notes or a skill about uCAD from before: the language (a small Python: every function, its arguments and the objects it returns, with the rules), how this service works, the reference examples, what is new. The language is at spec version ad65f6b97f now; a copy with another version is out of date.
Takes no parameters.
Read a reference example
The script of one of the reference examples listed by specs (by its id): a finished model built carefully in uCAD's language, to learn from before building something like it.
idrequiredBuild: run a uCAD script
Run a whole uCAD script on a drawing in the user's account (a new drawing when `drawing` is left out) and keep the result there. Returns the report (every solid with its size and place, warnings, print() output, or the error with its line), the drawing's id and link, and pictures of it. Each run replaces what the drawing's previous run made. The language is at spec version ad65f6b97f: if what you know of it is another version (or none), call specs first.
coderequirednameviewswidthheightdrawingspec_versionLook at a drawing
Pictures of a drawing as it is now (with anything the user changed by hand), from the sides asked for.
viewswidthheightdrawingWhat a drawing holds
What is in a drawing now: its solids and objects with sizes and places, flat shapes drawn by hand, and its script with line numbers.
drawingA link anyone can open
A link to a drawing that anyone can open, with no uCAD account: they see the drawing as it is now (and as it changes later) in uCAD, and can turn it around, measure it, cut sections, download it and edit a copy of their own; its script isn't in it. Use it when the user wants to show or send the model to someone else, or post it: the drawing's own link (?d=) opens only for the user, signed in. Each drawing has one such link: asked again, share gives the same one.
actiondrawingThe account's drawings
The drawings kept in the user's uCAD account, newest first: id, name, when changed, link (and the link anyone can open, for those shared).
Takes no parameters.
83% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
