I’d like to add my voice to the request that Unity MCP be made available for free.
Charging for Unity AI Assistant or other hosted Unity AI services makes sense. Those products likely involve ongoing infrastructure, model usage, and support costs. However, charging for MCP access feels much harder to justify from a customer perspective.
In many modern development workflows, MCP support is increasingly becoming part of the expected integration layer between tools, editors, and AI assistants. Several tools I use in my own GameDev workflow provide MCP access without an additional paid tier, including on free plans. In that context, placing Unity MCP behind a monthly subscription risks making Unity feel less open and less aligned with current developer expectations.
The concern is not that Unity should never charge for AI features. The concern is that MCP appears to be enabling interoperability rather than providing a complete paid AI product on its own. Charging for that interoperability may discourage adoption, reduce experimentation, and create frustration among the very developers Unity needs to keep engaged.
Unity’s stated principle of “Prioritize the greater good” and delivering value to customers would be better reflected by making MCP freely available, while monetizing the higher-value AI services built on top of it.
I’d encourage Unity to reconsider this pricing decision. A free Unity MCP would likely drive more goodwill, broader usage, and stronger long-term ecosystem value than the revenue generated by charging developers $10/month for access to what many now see as baseline tooling integration.
This is so fascinating to watch… there really is no moat or pricing power in chatbot land. Chatbot technology has already become completely commoditized and fungible in such a short timespan, even as it burns through company budgets.
Chatbots are coming to everywhere and any attempt by anyone to charge even a micro-cent more than the other guy will be met with lost traffic. It’s exactly like airline travel: the moment one company offered a flight at $1 less but you had to pay for luggage, everybody else lost business.
100% agree with this. Especially now that we are forced to use the Unity MCP and can’t use third party ones anymore with the new updated terms of use. That in itself looks like a money grab attempt while forcing all third party MCP’s out of business. That’s not good for progress either. Having a subscription for Unity AI/Assistant is fine. As long as it’s good/decent people will pay for it. To continue using AI directly in my Unity projects I even wanted to get it today, but after 4 different credit cards and paypal resulting in ‘Something went wrong with the payment’ I’ve given up on it.
Hi @Ivan-Murzak,
Thanks for the info! So yours bypasses Unity’s official MCP does it? I thought Coplay was supposed to do that, but when I tried Coplay it wouldn’t work without a Unity AI sub.
flights at $1 less? you really are out of touch with reality.
They were charging 3500€ to fly to Japan and now you can fly with an excellent company, full meals and all your luggage, not a budget company, for 1200€.
MCP is not a “chatbot”. It’s a bridge between AI and your tool.
And contemporary AI is not a “chatbot” either. It is a massive productivity multiplier.
I understand you may be losing money and feel bittter about it. But it’s good for most people who do not need to pay out of their nose a mediocre programmer to do in six weeks, what a competent coder could do in two with half the money but they do not bother because it is too boring for them.
It is true democratization of the digital field, and a bit of a lesson for those coders with the inflated ego and god complex posing as gatekeepers of people’s creativity.
Suggest you try it yourself as I have tried (as per the installation instructions provided to me) to no success. The issue isn’t about installing the MCP or how to connect (the MCP runs and connects fine) - the issue is that the connection gates through Unity’s AI framework which as far as I can tell is either unavoidable now or at the very least, violates Unity’s new terms of service. Unity’s AI framework (which Unity MCP is gated behind) is a paid service, hence you cannot ‘officially’ use an MCP without a paid Unity AI sub.
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:
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?
you really are out of touch with reality.
