 > **Tip:** You can easily generate this configuration format using the **Server Entry** and **Servers File** buttons in the Inspector UI, as described in the Servers File Export section above.
 
+You can also set the initial `transport` type, `serverUrl`, `serverCommand`, and `serverArgs` via query params, for example:
+
+```
+http://localhost:6274/?transport=sse&serverUrl=http://localhost:8787/sse
+http://localhost:6274/?transport=streamable-http&serverUrl=http://localhost:8787/mcp
+http://localhost:6274/?transport=stdio&serverCommand=npx&serverArgs=arg1%20arg2
+```
+
+You can also set initial config settings via query params, for example:
+
+```
+http://localhost:6274/?MCP_SERVER_REQUEST_TIMEOUT=10000&MCP_REQUEST_TIMEOUT_RESET_ON_PROGRESS=false&MCP_PROXY_FULL_ADDRESS=http://10.1.1.22:5577
+```
+
+Note that if both the query param and the corresponding localStorage item are set, the query param will take precedence.
