About unity-mcp-plugin
AnkleBreaker-Studio/unity-mcp-plugin
Unity MCP Plugin (UPM) — Editor bridge for AI-assisted game development. Enables Claude, Cursor & MCP-compatible AI to control Unity Editor with 268 tools: scenes, GameObjects, components, builds, profiling, Shader Graph, Amplify Shader Editor, terrain, physics, NavMesh & more. Free & open source.
Implements a stateful HTTP bridge on `localhost:7890` that persists across Play Mode domain reloads via SessionState, enabling real-time bidirectional control between MCP-compatible AI and the Unity Editor. Supports multi-instance editor discovery with automatic port affinity tracking and heartbeat-based session management to distinguish active from crashed editors. Conditionally exposes 268 tools across shader editors (Shader Graph, Amplify), multiplayer frameworks (MPPM), and profiling systems (Memory Profiler, Frame Debugger) based on installed packages.
About unity-mcp
wondeks/unity-mcp
A Unity MCP server that allows MCP clients like Claude Desktop or Cursor to perform Unity Editor actions.
Exposes a comprehensive set of Unity Editor operations—asset management, scene modifications, and game mechanics testing—through MCP's standard protocol, enabling AI clients to autonomously perform complex editor tasks. Acts as a bridge between MCP-compatible AI tools and Unity's Editor scripting API, communicating via the MCP protocol to translate high-level client requests into native Editor commands.
