1. Click on "Install Server".

2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.

3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Gamedev All-in-One MCP create a red spinning cube in Unity, then replicate it in Roblox and Blender."

That's it! The server will respond to your query, and you can continue using it as needed.

Here is a step-by-step guide with screenshots.

"Hey Claude, create a red spinning cube in Unity, then replicate it in Roblox and Blender."
