 Use the "+" button in your chat interface to access "Connectors," where you can enable/disable connectors per conversation.
 
+## The Add custom connector dialog, field by field
+
+<Note>
+  The two-step dialog described here is rolling out gradually. If your dialog shows a name, URL, and Advanced settings on one screen, your organization has the earlier version; the steps above still apply.
+</Note>
+
+**Name**: the display name shown in the connectors list.
+
+**Remote MCP server URL**: the HTTPS address where the server accepts MCP requests, for example `https://mcp.example.com/mcp`. After you continue, Claude checks the URL and pre-fills the authentication settings it detects, marked "Detected."
+
+**Authentication**: how people connect to the server.
+
+* **Always required**: each user signs in through the server's OAuth flow before using it.
+* **Required when the server asks**: Claude connects without credentials and prompts users to sign in when the server asks.
+* **None**: no sign-in. Anyone with access to the server URL can use the connector. If the server uses an API key, choose None and add the key under **Request headers**; Claude stores it as the connector's credential.
+
+**OAuth client** (shown unless you chose None): how Claude identifies itself to the server's authorization server.
+
+* **Use Anthropic's hosted client metadata** (recommended): the server reads Claude's client details from a URL Anthropic hosts (Client ID Metadata Document). Nothing to set up; the server must support it.
+* **No client ID — register one automatically**: Claude registers OAuth clients with the server as users connect (Dynamic Client Registration). Works with most servers, but adds client registrations over time.
+* **Use your own OAuth client**: enter a client ID you registered with the server. Leave the secret blank unless your authorization server requires one. See [Authentication for connectors](/docs/connectors/building/authentication).
+
+**Request headers**: fixed credentials such as API keys, sent on every request. See [Authenticating with request headers](#authenticating-with-request-headers).
+
+**Advanced > Transport**: set from the URL automatically; a URL ending in `/sse` selects the older SSE transport. Change it only if the server's documentation says to.
+
 ## Authenticating with request headers
 
 <Note>
-  Request header authentication is in beta. This feature is being slowly rolled out to customers; contact Anthropic for early access.
+  Request header authentication is in beta and available to a limited set of organizations. If you don't see the **Request headers** section in the Add custom connector dialog, your organization doesn't have access yet.
 </Note>
 
 If your MCP server authenticates with an API key, bearer token, or other fixed credential instead of OAuth, you can configure it in the **Request headers** section of the Add custom connector dialog. Claude stores each header value securely, does not show it again after you save, and sends it on every request to your server.
