Scene querying: get_scene, get_node, describe_node, find_nodes, measure. Scene mutation (undoable, atomic): apply_patch, create_level, create_wall, place_item, cut_opening, set_zone, duplicate_level, delete_node. Undo/redo: undo, redo. Export: export_json, export_glb (not_implemented stub). Validation: validate_scene, check_collisions. Each tool has: - Exported Zod input + output schemas - register<Tool>(server, bridge) wiring function - Bun test with happy-path + error-path coverage via InMemoryTransport 59 tool tests, all passing end-to-end through MCP protocol.
