pascalorg/editor
Pascal exposes a local-first 3D building editor through a CLI and MCP, giving agents structured scene tools while keeping projects on the local machine by default.
Pascal is an **open-source, local-first 3D building editor** built with React Three Fiber and WebGPU. Its CLI starts the editor and an authenticated **MCP service**, while projects persist in a local SQLite database.
Builders can connect agents through pascal mcp connect and install workflows for scene work or bounded furniture-fit checks. Use separate PASCAL_HOME directories and service processes when independent agents must work concurrently.

Builders can connect agents through pascal mcp connect and install workflows for scene work or bounded furniture-fit checks. Use separate PASCAL_HOME directories and service processes when independent agents must work concurrently. The npm beta is older than the repository’s **GitHub prerelease**, and optional tool fields may differ between installed and hosted versions. The project also requires one active agent client per local CLI service.
This extends MCP-backed agent work into a persistent local 3D scene editor, with bounded spatial workflows rather than browser or data retrieval. It also makes deployment topology part of the harness: concurrency requires separate homes and services, each service supports one active client, and clients must account for tool-schema drift between releases.
