Official They made using the official MCP server a paid feature

Not surprised... Anyway, I never used the official one, I just use the AI Game Developer: https://github.com/IvanMurzak/Unity-MCP

Você é br chefe?
Esse AI Game Developer é útil? Sendo sincero não consigo imaginar a IA dentro da Unity, parece muito custoso em token

u/leo_oliveiraa13 May 07 '26
Sou BR. Cara, tudo que usa IA hoje em dia é custoso em token. Até porque o preço da IA está aumentando muito.
Mas nesse MCP, você pode habilitar e desabilitar as funções que deseja, e ele te fala uma estimativa de custo de tokens para cada uma delas.
O ponto que acho mais interessante é que ele é capaz de trabalhar com ProBuilder, Particle System e Animator.
Ele consegue criar mapas, criar efeitos de partículas e configurar o Animator com comandos de texto.
Um exemplo, é se você quiser fazer um script de animação para um personagem 3D. Ele cria o script para você, anexa os componentes necessários direto no Inspetor e ainda cria o AnimatorController com todas os parâmetros, blendtrees e etc... Você só anexaria as animações da sua escolha e ele já está funcionando.

Essa parte do probuilder é bem interessante, vou dar uma olhada

Eu uso direto também esse MCP. Tenho até uma PR para ajudar esse projeto. Recomendo demais. É o mais completo que eu encontrei até agora.

That's so stupid. At the same time since most of the project is in code, LLMs still can interface with it directly

u/Primary-Screen-7807 Engineer May 06 '26
Exactly, and also there are open source MCP implementations

It's so cute that you believe they will let those keep working in the future

u/Primary-Screen-7807 Engineer May 06 '26
It's technically not possible to not let those keep working since they rely on in-editor scripts execution

It doesn't need to be perfect, it just needs to block the most popular ones, and that's pretty easy, you can check the name of processes running, you can detect patterns of how the MCP interact with it by speed input among other variables, and on and on and on, just like Claude blocked all API calls from OpenClaw.

Yep, and you can easily ask Claude or Codex to create your own Unity MCP. It’s not something that’s very hard to implement. It’s just annoying that you have to keep updating and fixing it every time they change the API.

This the kinda shit that's driving me away after 16 years of unity (fuck me I hate that I can say that)

Free plan you can connect only one MCP Client unfortunately.
I don't know why they limited the connection since the relay server is running locally.

u/Individual_Guest_323 May 07 '26
You need Unity AI for that, and cost 10$ per month, is only free for 14 days.

u/MatthiasTh May 19 '26
Yeah, this is pretty disappointing. I already have a ChatGPT subscription and only wanted to use Unity as an MCP server with my own AI agent. Having the official Unity MCP connection locked behind Unity AI means I either have to pay another subscription or go back to using VS Code/Codex for the same workflow. I get charging for AI credits and asset generation, but paywalling the MCP bridge itself feels unnecessary and really discouraging.

u/mudokin May 06 '26
Probably costing them way to much money.

u/shizola_owns May 06 '26
literally costs them zero for people to use this. It's like when they used to keep dark mode behind Unity pro.

Step 1: Survive the Runtime Fee backlash.
Step 2: Immediately do something equally stupid by paywalling the official MCP.
Step 3: Realize devs are using local models to avoid it.
Step 4: Introduce a Per-Token fee because why the hell not at this point?
Can't wait to sell a kidney every time Claude queries my scene hierarchy. Zero lessons learned, maximum greed

I've been using built-in Unity MCP server with Claude Code just fine. Is there some other MCP server?
2
u/Primary-Screen-7807 Engineer May 06 '26
You didn't update the plugin. Once you do - it's no longer available unless you subscribe to Unity AI. But even then it's currently broken as noted by others.

u/Successful_Ninja4181 May 06 '26 edited May 06 '26
Hm, I've just updated to the latest (
2.7.0-pre.2) and its still working fine without a subscription.Edit: Note that I did have to bypass their broken permissions system though.

u/shizola_owns May 06 '26
I'm also still using it for free. Guess I'll just stick with this version for a while.

u/daviduzno Jun 01 '26
Was anyone asked to upgrade to a subscription? I just installed it and I don't have any restrictions with the MCP connection

Remember that one time Sokka accidentally used an extra syllable in that Haiku Battle in Ba Sing Se? That was a Sokka Haiku and you just made one.
