Your agent.
Your worldbuilding tools.
Connect through MCP and describe the world you want. Your agent can sculpt terrain, carve rivers, grow forests, place objects, and set up zones using Skyfold’s own tools.
Be precise about the place.
Select an area and prompt the changes you want. Edits stay inside the boundary and blend into the world around it.
Keep the result, refine it, or undo the whole edit. Take over by hand whenever you want.
