Why Unity AI Bridge?
Most AI coding assistants can read and write files, but they are blind to the Unity Editor — they can't inspect your scene, tweak materials, run tests, or profile performance. Unity AI Bridge gives AI full editor access.
Key Advantages
- 65 tools, 15 categories — Scene, GameObject, Assets, Prefab, Script, Profiler, LightProbe, Screenshot, Runtime, Tests, and more. Covers the full editor workflow, not just file I/O.
- File-based IPC, not WebSocket — No open ports, no firewall issues, no connection drops. Survives recompilation, play-mode transitions, and editor restarts gracefully.
- Zero external dependencies — Pure Python stdlib CLI/MCP server, self-contained C# Unity package. No pip install, no npm, no Node.js runtime.
- Every major AI IDE — Claude Code (Skill mode), Cursor, GitHub Copilot, Windsurf, Claude Desktop (MCP mode). One Unity plugin, all IDEs.
- 5-line extensibility — Add custom tools with
[BridgeTool]attribute. Auto-discovered, auto-serialized, auto-documented. No registration code needed. - Production-tested — Built for and battle-tested in a large-scale open-world Unity game (50+ developers, 2M+ lines of C#).
