Control Unity Editor with natural language. Tell Claude Code, Cursor, or any MCP-compatible AI what you want — and Unity actually does it.
Editor Eye is an MCP (Model Context Protocol) server for Unity Editor. It gives your AI assistant real eyes and hands inside Unity — the AI can see your Game/Scene View, drive Play Mode, inspect UI, and execute C# directly. No cloud, no subscription, no login. 100% local.
Say things like:
- "Make the breast physics softer, and reduce the damping."
- "Place 100 enemies randomly within a 50m radius, then bake NavMesh."
- "Add a 'blink off' toggle to the Expression Menu."
- "Build a VRChat world where pressing a button turns on the light."
…and watch Unity actually do it.
- 👁 Vision — the AI sees the Game/Scene View (screenshots & captures), not just text.
- 🎮 Play Mode automation — simulate keyboard/mouse input to run and test your game.
- 🎛 65 specialized tools (Pro) — covering VRChat, ModularAvatar, AvatarOptimizer, NavMesh, Timeline, VFX Graph, ProBuilder, and direct C# execution.
- 💻 Local & buy-once — no cloud, no subscription. Works with Claude Code, Claude Desktop, Cursor, Codex, VS Code, and any MCP-compatible client.
- 🧩 Single-package design — drops into your existing Unity project cleanly.
- PhysBone tuning, Expression Menu editing, BlendShape composition
- ModularAvatar merge, AvatarOptimizer Trace and Optimize
- Building VRC worlds: Pickup, Mirror, Station, Udon — all by conversation
- Scene assembly, prefab placement, batch operations
- NavMesh baking, Cinemachine setup, Timeline tracks
- Animator Controller editing, VFX Graph, Shader inspection
- Profiler runs, Play Mode automation, NUnit test execution
- Asset generation: chiptune BGM, SE, pixel sprites (Pro)
