Unity Developer Tools

AI-powered development toolkit for Unity game development in Cursor IDE.

18 skills -- 8 rules -- 4 MCP tools -- 20 snippets -- 5 templates

What is this?

Unity Developer Tools is a plugin for Cursor that teaches its AI assistant how to build Unity games and tools. Once installed, you can ask the AI to:

  • Scaffold MonoBehaviours, ScriptableObjects, Editor windows, and ECS systems
  • Look up Unity APIs by name, namespace, or category
  • Generate shader patterns for common effects (dissolve, outline, hologram, etc.)
  • Get platform-specific defines, capabilities, and build recommendations
  • Write code that follows Unity 6 best practices automatically

Quick start

git clone https://github.com/TMHSDigital/Unity-Developer-Tools.git
cd mcp-server && pip install -r requirements.txt

Open the Unity-Developer-Tools folder in Cursor, then ask the AI to scaffold a script, look up an API, or generate a shader effect.

For a detailed walkthrough, see the Getting Started guide.

Features

  • Script scaffolding -- Generate MonoBehaviours, ScriptableObjects, Editor windows, and ECS systems following Unity 6 conventions
  • API lookup -- Search common Unity APIs by name, namespace, or category via MCP tools
  • Shader patterns -- Get HLSL code and Shader Graph node setups for common effects
  • Performance-aware coding rules -- Catch deprecated APIs, allocation-heavy patterns, and common mistakes
  • Snippet library -- 20 copy-paste-ready code patterns for C#, shaders, and Visual Scripting
  • Render pipeline detection -- Automatically adapt guidance to URP, HDRP, or Built-in
  • Platform targeting -- Platform-specific defines, capabilities, and build recommendations
  • Template projects -- 5 starter templates for 2D, 3D, UI, architecture patterns, and editor tools

Supported workflows

Workflow Description
MonoBehaviour Classic Unity scripting with lifecycle methods
ScriptableObject Architecture Data-driven design with events, variables, runtime sets
ECS/DOTS High-performance data-oriented tech stack
Visual Scripting Node-based scripting for designers
Editor Tooling Custom inspectors, windows, overlays, gizmos

Supported render pipelines

Pipeline Status
URP (Universal) Primary -- recommended for all new projects
HDRP (High Definition) Supported -- maintenance mode guidance
Built-in (Legacy) Migration guidance -- deprecated in Unity 6.5

Skills teach Cursor how to handle Unity development prompts. Rules enforce Unity best practices in your code. The MCP server provides programmatic tools so skills can scaffold scripts, look up APIs, and generate shader patterns directly.
