Call to make Unity MCP usage free

[soleron]

@Talthilas

I just tried Claude Code and Cursor using Coplay MCP. No issues.

Also, the terms do not seem to say any such thing. Although yes, some parts are vague to give them “gotcha” opportunities if a legal situation arises.

What they say, is that AI should not be trained on data and source code from Unity. Or user data acquired from their Services. i.e. someone (say a large mobile publisher or studio) connecting their AI to Unity Game Services (or through a deal allow some third-party AI to do it) and scraping tons of user data and Unity source code. Which is absolutely reasonable. Or someone connecting to data from their advertising services and training their AI on advertising performance etc.

More clarity here:

New Terms of Service: Is Unity Restricting Local AI Tools and AI Training?

Yep, you basically have that right. Using AI in your projects in order to help you build, or train your own agents is OK, as long as you’re using it on your own stuff. You can’t train machine learning or AI models on Unity itself or on data derived from it without our authorization, you can’t point automated scrapers or bots at Unity’s APIs or the Asset Store, and AI agents, LLMs, and MCP clients/servers need to connect through Unity’s Authorized Agentic Access framework rather than poking at t…

New Terms of Service: Is Unity Restricting Local AI Tools and AI Training?

The best way I can put it is: You can use and train AI on your stuff, but you can’t on our stuff. So, when you wrote this Allowed: local automation own-project research synthetic data from own scenes RL/simulation/testing inside own projects Not allowed: scraping Unity services cloning Unity documentation or Asset Store data training models on Unity proprietary materials bypassing subscriptions, rate limits, or security using Unity data for competitive replication you got it, though I …

New Terms of Service: Is Unity Restricting Local AI Tools and AI Training?

Sorry for the delay due to the long July 4th weekend. Due to the amount of things to respond to, I am going to use an informal tone. Just a reminder, none of this constitutes legal advice. I’ll just tackle these numerically: Yes, that is fine. If the local automation is only interacting with your own files, then you’re in the clear. If it is driving the Unity editor, that is where the terms come into play. Instead of responding to this right here, I will put something at the end of this post B…

There are still some vague areas which need clarifying, but their representatives say until the vetting process is complete there are no issues with third party MCP. After they have vetted the providers, we should all use providers that Unity has approved.

I suppose this is also a way for them to see what competitors do learn and improve their MCP and Assistant which is lagging compared to others.

We do not want anyone scraping our projects and, for the more serious developers, actual user data to train their models either. Do we know if some of them do? Wouldn’t it be great if Unity provided that assurance?
