pascalorg/editor

An open-source, local-first 3D building editor built with React Three Fiber and
WebGPU. Run it in the browser or from the CLI, and connect AI agents through MCP.

A first look at Pascal Next
Explore the live demo — a real home reconstructed
in detail, from its rooms and finishes to the structure and systems behind the walls.
This hosted preview explores the direction of the next Pascal editor; the experience
shown here is not yet part of the open-source editor release.

We are exploring what this could make possible for facility management, home services,
architecture, home building, and infrastructure.

Run the Editor Locally
Node.js 22.13 or newer can create a persistent local Pascal installation without
cloning this repository:
The CLI starts the editor and an authenticated MCP service in the background, selects
collision-free loopback ports, and keeps projects in ~/.pascal/data/pascal.db. The npm
package holds the CLI and that MCP service; the web editor runtime is downloaded once per
version on the first command that starts the editor and verified against a digest published
inside the package. Configure an agent to launch pascal mcp connect, which needs neither
the editor process nor that download. Install the pascal command with
npm install --global @pascal-app/cli. See Run Pascal locally
for pnpm/Bun commands, project management, MCP setup, updates, storage paths, and
troubleshooting.
Use one active agent client per local CLI service. The standalone local HTTP runtime shares active scene state between clients; use separate PASCAL_HOME directories and service processes when independent concurrent work is required.
Self-host it
The editor ships as one container, ghcr.io/pascalorg/pascal-editor, tagged with the
same version as the npm packages (latest follows stable releases). Projects live in
SQLite under /data; one admin password protects the instance; PASCAL_PUBLIC_URL is
read at runtime, so the same image serves any domain.
See SETUP.md, "Self-hosting" for the compose file, the
variables, agent access and public embeds.
Agent skills
Install Pascal's public agent workflows from this repository with skills.sh:
Claude Code users can install the same canonical skill source as a plugin:
The Claude plugin also supplies the local pascal mcp connect server. Install and start the Pascal CLI first, and keep pascal on the PATH used to launch Claude Code. This local connector needs no Pascal account or API key and does not upload projects automatically. Its plugin root is this repository's skills/ directory, so an install copies only the skill bundles and their plugin metadata rather than the repository.
The plugin bundles two servers: the local pascal connector above and a hosted pascal-hosted server for https://editor.pascal.app/api/mcp, which prompts for an optional Pascal API key at enable time and stores it in the OS keychain. Leave the key empty to run local-only.
Claude Code 2.1.258 loads both the user-scoped pascal server created by pascal mcp setup claude and the plugin-provided server. Remove the manual entry before reloading or restarting Claude Code so only the plugin owns the connection lifecycle:
Use /mcp to remove or disable any project- or local-scoped Pascal connection too. Leaving both connections active violates the one-active-agent-client-per-local-service requirement. When the intended project is hosted in a Pascal account or organization, disable the plugin-provided local server in /mcp and configure the hosted endpoint from the skill setup guide instead.
