At 23,817 stars, 2,954 forks and only 20 open issues, MIT-licensed, pushed 2026-09-12 at 05:11 UTC after gaining 514 stars today. It is an open-source architectural modeling editor that exposes its own operations through a CLI and MCP server so a coding agent can drive the model directly rather than through the GUI. Most agent-facing tooling this year has been text, code or browser; this is one of the few putting a geometry kernel behind MCP.
