# UEFN setup

Goal: get one confirmed MCP round trip with the least setup.

## Checklist

1. Confirm the user is in a UEFN version that includes Unreal MCP support.
2. Confirm the required UEFN editor scripting/MCP toolset options are enabled.
3. Confirm the MCP server is running.
4. Prefer the default loopback endpoint `http://127.0.0.1:8000/mcp`.
5. Ask the MCP server to discover/list toolsets.
6. Treat successful toolset discovery as the connection proof.

Do not guess that the connection works because configuration files exist.

If the user changed the port, follow [references/checklist.md](references/checklist.md).
