Hi there, I’m using my own AI model base on LM-Studio. Is running using a IP address within my network. I’m using that IP to access it using my Mac and throut Xcode consume the AI Agent. I was trying to follow up the documentation provided by Unreal about MCP (Unreal MCP in Unreal Editor | Unreal Engine 5.8 Documentation | Epic Developer Community) but something is missing. I’m not understanding why we have the local MCP ip address, and where should I put my own server address. If someone else adchieve this and can share some insight, I’ll really appreciated.
Looks like the part that’s blocking you is by design: the UE MCP server binds to loopback only (127.0.0.1:8000/mcp) and has no auth - it’s not reachable from another machine on your network, no matter what the client is.
So your agent (or whatever bridges LM Studio to MCP) has to either run on the same machine as the editor, or reach it through an SSH tunnel: ssh -L 8000:127.0.0.1:8000 user@editor-pc from the Mac, then point the client at http://127.0.0.1:8000/mcp locally.
Also note LM Studio itself doesn’t speak MCP, you need an agent harness in between that does (it drives the model and calls the MCP tools). The editor-side check that the server is up: GET http://127.0.0.1:8000/mcp → HTTP 405 means alive.
