 | `MCP_PROXY_FULL_ADDRESS`                | Set this if you are running the MCP Inspector Proxy on a non-default address. Example: http://10.1.1.22:5577 | ""      |
+| `MCP_SERVER_URL`                        | Set this to configure the default MCP Server to connect to on startup. Example: http://localhost:8080        | ""      |
 
 These settings can be adjusted in real-time through the UI and will persist across sessions.
