AI co-debugging for Unity. Stop narrating your gameplay—your AI can see the game.
Aether bridges your Unity game to Cursor, giving the AI complete context: live state, event history, crashes, and GTML snapshots. Two modes: Live Inspector (real-time object inspection) and Replay Mode (time-travel debugging after a bug).
/add-plugin aetherThat's it. The bridge auto-downloads on first use.
First time in a Unity project? Run this once from your project root:
npx aether-initThen reload Cursor (Ctrl+Shift+P → Reload Window), enter Play mode, and ask your AI: "What's the state of my game?"
Unity 2021.3+, Node.js 18+, Cursor with MCP
The plugin includes a skill that guides the agent to use Aether when:
- Debugging Unity gameplay behavior
- Analyzing crashes, NullReferenceExceptions, or runtime errors
- Inspecting object state during Play Mode
- Asking "what happened before this crash?" or "why is this object behaving wrong?"
