What it does
Pascal is an open 3D architectural editor that gives an agent semantic tools over MCP. The agent can create rooms and buildings, inspect a project, make spatial edits, validate a scene and return an editor link. A local CLI launches the editor and an authenticated MCP service on free ports and keeps projects in a local database, with no key required. There is also a hosted MCP endpoint with an optional key for working with projects in a Pascal account.
Who it is for. For designers, architects and developers who want to build and edit 3D scenes through an agent.
Good fit when
- You want the agent to build or change a room or building model
- You need scene validation and an editor link
- You want to work on a 3D project locally without an account
Not a fit when
- You need a full CAD with strict engineering calculations
- You cannot run a local service or Node.js 22.13+
Example request
Build a one-room apartment model in Pascal and send me the editor linkMCP
- Transport
- stdio, http
- Authentication
- key is optional
Environment variables
PASCAL_API_KEYsecret- Key for the hosted endpoint and cloud projects; not needed for local work.
Limitations
The local mode needs Node.js 22.13 or newer, and the editor downloads a runtime per version once and verifies it against a digest. Keep one active agent client per local service. The hosted endpoint requires a Pascal account; the key is stored in the OS keychain and is only needed for cloud projects.
How to disable. Remove the pascal-agent-skills plugin via /plugin and delete the pascal MCP entries via /mcp; optionally uninstall the CLI (npm uninstall -g @pascal-app/cli).
FAQ
Do I need an account and a key?
Not for local work. A key is only needed for the hosted endpoint and cloud projects.
How are the skills installed?
Via npx skills add pascalorg/editor or as a Claude Code and Codex plugin from the repository marketplace.

README in short
The README shows Pascal as an open 3D architectural editor with a local CLI, MCP tools and ready agent workflows. The local @pascal-app/cli launches the editor and an MCP service with no account, while a hosted server uses the editor.pascal.app/api/mcp endpoint and an optional key. The pascal-3d and furniture-fit skills install via skills.sh or as a Claude Code and Codex plugin. MIT licensed.
