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

Scaffold Unity scripts, look up APIs, generate shader patterns, detect render pipelines, and write optimized C# -- all from within Cursor's AI chat. Covers the full Unity development lifecycle from project setup to platform deployment.

First time here? The Getting Started guide walks you through every step -- from installing prerequisites to building your first Unity project with AI assistance. No prior Cursor plugin experience required.

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.

Already have Git, Python 3.10+, and Cursor installed? Here's the short version:

git clone https://github.com/TMHSDigital/Unity-Developer-Tools.git
# Open Unity-Developer-Tools folder in Cursor (File > Open Folder)
cd mcp-server && pip install -r requirements.txt

Then ask the AI agent to scaffold a MonoBehaviour, look up an API, or generate a shader effect.

Need more detail? The Getting Started guide covers installing prerequisites, troubleshooting, and building your first project step by step.

• 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 (dissolve, outline, hologram, etc.)
• 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

The companion MCP server provides programmatic tools that Cursor's AI agent can call directly. Configuration lives in .cursor/mcp.json.

Prerequisites: Python 3.10+

cd mcp-server
pip install -r requirements.txt

The server starts automatically when Cursor invokes an MCP tool.
