Community Unity 2019.4 compatibility implementation

[ibelongedtoyou]

Hi CoplayDev team and community,

Thank you for open-sourcing MCP for Unity.

I’ve published an independent, community-maintained compatibility
implementation for projects that need to remain on Unity 2019.4:

Repository:
https://github.com/ibelongedtoyou/unity-mcp-2019

Unity Package Manager:

• Stable release: https://github.com/ibelongedtoyou/unity-mcp-2019.git#v0.3.0
• Latest development version: https://github.com/ibelongedtoyou/unity-mcp-2019.git#main

The project was led and completed end-to-end by OpenAI Codex,
including architecture planning, implementation, documentation,
testing, Unity 2019 compatibility validation, packaging, and release
preparation. The repository owner provided the project goals,
requirements, and final approval.

It has been validated with Unity 2019.4.28f1 and provides MCP tool
and resource support for Unity Editor automation.

This is an independent community project and is not affiliated with
or endorsed by CoplayDev. I’m sharing it in case it helps developers
who cannot upgrade their existing Unity projects.

Feedback and compatibility reports are welcome. Thank you!
