What you get

The Most Advanced MCP Server for Unity Editor

  • execute_code First — — Optimized around one in-memory C# execution tool for rich editor/runtime orchestration. See execute_code: In-Memory C# Execution below for details
  • Default Safety Checks — — execute_code now has persistent default-on safety toggles, including a stricter filesystem guard for clients that do not expose per-call arguments clearly
  • Play Mode Automation — — Enter play mode, simulate keyboard/mouse input, capture screenshots, inspect logs, and validate behavior from the same MCP session
  • Project Context Built In — — Exposes live resources for project state, active scene, selection, compilation, console output, and MCP interaction history
  • Focused by Default, Full When Needed — — core exposes a compact high-signal toolset; full exposes all 156 tools
  • Single Unity Package — — No extra approval UI, no external daemon to click through, and no Python requirement for the Unity-side plugin itself
