Pascal Editor

Pascal Editor is a 3D building editor built with React Three Fiber and WebGPU. A single command, npx @pascal-app/cli editor, sets up a persistent local installation that keeps projects in a local database and starts an authenticated MCP service beside the editor, so an agent can be pointed at the scene. The repository is a Turborepo monorepo split into published npm packages — scene schemas and registry contracts, the rendering runtime, editing tools and UI, built-in node definitions, the CLI, the MCP server, and optional capture-session packages. Handy if you want the viewer runtime inside your own React app rather than the standalone editor.
