Installation URL/instructions out of date?

[Grymlot]

I am following the instructions for adding via git URL, but the URL doesn't work. Unity gives a generic error and if I ask Copilot about why it's not working, it says it's not a valid package URL. I have now installed via the Unity Asset Store, but that version is 9.0.3 from January so I'm missing out on alot of the latest stuff. I feel like this worked for my first test project like 4 days ago. Any ideas?

Yeah the Asset Store one is slightly out of date. I just add package from git url and it worked. Are you adding it while there already exists a MCP for Unity package?

Possibly? I had a test project and I added MCP for Unity with the git URL successfully. A couple days later I made a new test project and it did not have MCP for unity. So I went to add it with the git URL and ran into problems… is there something I’m supposed to be clearing out between projects? For example, Claude code was talking about a Settings.json file somewhere.Sent from my iPhoneOn Mar 29, 2026, at 8:02 PM, Shutong Wu ***@***.***> wrote:Scriptwonder left a comment (CoplayDev/unity-mcp#999) Yeah the Asset Store one is slightly out of date.

Well it's definitely possible something was conflicting. I uninstalled it from both of my projects and uninstalled the other MCP for Unity package I had tried earlier as well. Then I tried again installing via git URL and this path worked: "https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity"
