# URL parameters

> Open the Inspector with a selected server, tab, or embedded layout.

Use URL parameters when you need a link that opens the Inspector on a specific server, starts a connection automatically, or restores a tab.

## Parameters

| Parameter        | Purpose                                                                                                                           | Values                                                                                            |

## Select or connect to a server

Use `server` when the Inspector should select a saved server by URL:

```text theme={null}
/?server=https://mcp.example.com/mcp
```

If the server is not saved yet, the Inspector treats the HTTP(S) value like `autoConnect` and connects to it.

## Auto-connect on load

Use `autoConnect` when a link should create the connection immediately:

```text theme={null}
/?autoConnect=https://mcp.example.com/mcp
```

For advanced connection options, pass a URL-encoded JSON object. The `url` field is required.

```json theme={null}
{
  "url": "https://mcp.example.com/mcp",
  "name": "Example server",
  "transportType": "http",
  "connectionMode": "auto",
  "connectionType": "Direct"
}
```

Supported JSON fields are `url` (required), `name`, `transportType` (`"http"` or `"sse"`), `connectionMode` (`"auto"`, `"direct"`, or `"proxy"`), `autoProxyFallback`, `connectionType` (`"Direct"` or `"Via Proxy"` for older links), `customHeaders`, `auth`, `requestTimeout`, `resetTimeoutOnProgress`, and `maxTotalTimeout`.

<Tip>
  When passing a JSON object for **autoConnect**, URL-encode the value so special characters are valid in the query string.
</Tip>

## Open a tab

Use `tab` by itself to restore a view, or combine it with `server` or `autoConnect`.

```text theme={null}
/?server=https://mcp.example.com/mcp&tab=tools
```

The Inspector also updates `tab` as you move between server tabs, so refreshes keep the current view.

## Embedded mode

Use `embedded=true` when the Inspector is hosted inside another UI, such as an iframe.

```text theme={null}
/?embedded=true
```

Use `embeddedConfig` with a URL-encoded JSON object when the embedded host needs styling overrides.

```json theme={null}
{
  "backgroundColor": "#f5f5f5",
  "padding": "16px"
}
```

## Example links

Open the hosted Inspector and connect to a server:

```text theme={null}
https://inspector.mcp-use.com/inspect?autoConnect=https://your-server.com/mcp
```

Open the hosted Inspector, connect to a server, and show Tools:

```text theme={null}
https://inspector.mcp-use.com/inspect?server=https://your-server.com/mcp&tab=tools
```
