Unity docs RAG for easier vibe-coding

[novel egret]

Hey everyone, I built this for myself and ended up finding it genuinely useful, so I wanted to share it.

I made "UnityRAG": a local Unity docs MCP that complements Codex / Claude / Cursor / Copilot by grounding answers in official, version-specific Unity docs with citations.

For me, it improves both:

• vibe-coding loops (fewer hallucinated steps / dead-end edits)
• technical Unity questions (more accurate API/version-specific answers)

If anyone wants to try it, I’m happy to help with setup and run a quick side-by-side on one of your real prompts.

Hi there, thanks so much for putting this together. I’m really curious, have you had a chance to compare the knowledge quality after adding RAG with Unity AI’s responses? I’d love to understand what differences you’re seeing.

If you’re open to it, I’d be happy to set up a short video chat to learn more about how you’re using AI in your workflow and what’s working well or not so well. I’m a product manager on the Unity AI team, and conversations like this are incredibly helpful for us.

Thanks again for sharing your work.

Hey @dark quarry, really appreciate the kind message, and yes, I’d be happy to do a short video chat and share how I’m working / what’s working well vs what isn’t.

I’m building an indie game in my free time and using AI a lot in a practical Unity workflow (VSCode + Codex and Unity side-by-side): mostly script-heavy gameplay/system implementation, plus occasional shaders/UI. I built UnityRAG because I kept running into the same pattern: confident answers based on mismatched/older Unity docs, hallucinated steps, and implementations that look plausible but don’t map well to the Unity version/workflow I’m actually using.

I haven’t personally used Unity AI (in-editor) yet, so I can’t compare it to my workflow today. I mainly use Codex since I already have ChatGPT Plus, but I’d be happy to try Unity AI and share notes.

Feel free to DM me here (or email me) and we can set something up.

Hey, I tried it out and it's pretty cool. I also extended it a little bit to "download" package docs for packages used in a project.

really cool, does the extension work nice? I'd love to see what you did if you forked
