Why can’t my client connect to the server?

Ensure the URL includes the `/mcp` path (e.g., `http://127.0.0.1:8422/mcp`). If you changed the port, run `MCP.Restart` in the Unreal console after saving the new port.

How do I refresh the tool list when a client doesn’t see updates?

In the Unreal console, run `MCP.Reload`. If that doesn’t work, use `MCP.Restart` and then reconnect the client.
