Summer Engine (Oct 16) ships hosted MCP (https://mcp.summerengine.com/mcp), local `summer mcp`, and a full CLI so Claude Code/Codex/Cursor can generate assets, drive the engine, publish store pages, and pull analytics—`summer_search`/`ops search` map plain language to exact ops; CLI-only setup via skills with `--dry-run`/`--json` for safe agent scripting.
Kuaishou Kling AI fully rolled out Kling 4.0 (Oct 15): native 3–30s single-pass video, up to 10 keyframes, Omni Reference with ~15 multimodal inputs, smoother motion/camera control. Creation UI refreshed; developer path includes MCP and CLI so coding agents can drive generation without only the web UI. Feature page + official IR release; native 4K/HDR and broader enterprise API still listed as coming soon on some coverage.
