## What it does

The server connects an AI agent to Pascal’s scene editor. It can create rooms and walls, add doors, place objects, and set zones. Load a scene from a file or save scene data to a local SQLite database. When the editor and server use the same data directory, the editor can receive the server’s changes.

Run it with Node.js 22.13 or newer, or Bun. It works without a browser or an external database service. Before writing changes, the server checks the saved scene version; if another process has saved a newer version, reload the scene before continuing. Bun installs also need `@pascal-app/core` as a peer dependency.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://editor.pascal.app/api/mcp`
