Edit saved projects
An MCP client must select an exact project that the signed-in account owns. Project names alone are not authorization.
Check /mcp for this deployment's connection status. Widget and download capabilities depend on the client; authenticated ChatGPT host acceptance is still pending.
Select and inspect
List your projects, read the chosen scene and note its project ID and revision. Never ask an AI client to guess a private project ID.
Write with conflict protection
Mutations use expectedRevision and requestKey. A stale revision returns a conflict instead of overwriting editor changes. Reload the scene, inspect the difference, then retry intentionally.
Undo and reopen
The MCP change journal supports scoped undo/redo; browser editor history is a separate session concern. Confirm the final project from Projects after saving.
