Common questions about connecting and running FunseaAI Unity.
What is the Unity MCP server and what can it do?
It's a stdio bridge that lets you control and query a local Unity Editor instance from an AI chat interface. You can automate scene manipulation, query GameObjects, manage assets, and run editor workflows programmatically.
How do I install and set up the Unity MCP server?
Install the package FunseaAI.Unity.Mcp@0.1.7 into your Unity project. The server communicates via stdio, so configure your MCP client to launch it as a local subprocess connected to your running Unity Editor.
Does this work with remote Unity instances or only local?
The registry metadata indicates this is a stdio bridge for a local Unity Editor. Remote instances are not mentioned in the available documentation; check the FunseaAI/unity-mcp repository for details on remote support.
Is there a cost to use the Unity MCP server?
The server itself appears to be open-source (hosted on GitHub). You only pay for your MCP client and any AI model API calls you make through it.
What happens if my Unity Editor crashes while the MCP server is running?
The stdio connection will break and the MCP client will lose communication. You'll need to restart the Unity Editor and reconnect the MCP server to resume operations.
