+== Rate limits for API requests
+To ensure API stability, optimize resource usage, and maintain service quality for all users, ThoughtSpot limits the number of public API requests allowed per client to prevent excessive requests from reaching application servers.
+
+By default, on instances running 26.2.0.cl and later, a global rate limit of 100 requests per second per client IP is enforced at the cluster level for all public APIs. This limit is applied per client IP across all public APIs combined, not per endpoint. If a client IP exceeds this combined rate limit, a burst of 10 additional API requests is allowed before rejecting the requests with the 'HTTP 429: Too Many Requests' error.
+
+For async status endpoints such as `/api/rest/2.0/metadata/tml/async/status`, up to 100 requests per minute per client IP are allowed, with a burst of 100 requests before requests are rejected with an HTTP 429 error.
+
+These rate limits are enforced by default on all ThoughtSpot instances. Currently, rate limits are applied at the cluster level; Org-level rate limits are not supported.
+
+ThoughtSpot administrators can monitor logs, add or update rate limits via TSCLI, and adjust these settings for different environments (dev or prod)  as required.

+== SDK library for embedding Spotter
+ThoughtSpot provides the following Visual Embed SDK libraries for embedding Spotter capabilities in your app:
 
 * xref:embed-spotter.adoc[`SpotterEmbed`] +
-To embed the full Spotter interface with a conversation panel that allows natural language queries, data source selection, and interactions with AI-generated Answers, use the `SpotterEmbed` component.
-For more information, see xref:embed-spotter.adoc[Embed Spotter].
+Use this SDK component to xref:embed-spotter.adoc[embed the full Spotter experience] in your app. The features in a Spotter embed vary based on the Spotter version.
+
 * xref:embed-spotter-agent.adoc[`SpotterAgentEmbed`] +
-The Spotter Agent embedding, also known as `bodyless` embedding, allows you to integrate natural language data search and analysis into your own applications or chatbot. Unlike the standard Spotter embed, which provides a ready-made search bar and interface, the `SpotterAgentEmbed` component is designed for deeper customization, allowing full control over user experience and workflow of embedded analytics. It allows you to build your own UI or agent experience, route user questions to ThoughtSpot, and receive structured answers and visualizations.
+Also known as `bodyless` embedding, `SpotterAgentEmbed` allows you to integrate Spotter capabilities into your own applications or chatbot, route user questions to ThoughtSpot, and receive structured answers and visualizations. Unlike the full Spotter experience, the "bodyless" embed includes only a prompt panel with no additional buttons or selectors.

-==== Override icons
-To override the icons, you must first identify the icon ID, create an SVG file to replace this icon, and add the SVG hosting URL to your embed customization code.
+[#configControls]
+== Customizing embedded Spotter interface
+When you embed Spotter, you'll notice that the embedded component loads an initial page with a prompt interface. The look and feel of this page vary depending on the Spotter version used for embedding.
 
-The most common icon ID to override is `rd-icon-spotter`, the default Spotter icon.
+=== Spotter Classic and Spotter 2 experience
+If you have embedded Spotter Classic or Spotter 2, the initial page includes a prompt bar for user input, a data source selector, and the UI options to preview data and reset a Spotter session.

+
+To enable new chat interface and chat history features, set the `updatedSpotterChatPrompt` and `enablePastConversationsSidebar` attributes to `true`, as shown in this example:
 
 [source,JavaScript]
 ----
- init({
-     //...
-     customizations: {
-         // Specify the SVG hosting URL to overide the icon, for example Spotter (`rd-icon-spotter`) icon

+
+==== MCP connectors and resource selection icon
+A Connector is an external MCP server or tool, such as Google Drive, Slack, Notion, Confluence/Jira, which can be used as a data source in Spotter sessions. ThoughtSpot administrators can configure connectors to enable Spotter users to include both structured and unstructured data in their conversation sessions.
+
+If the new prompt interface in Spotter 3 is enabled, the Spotter page displays the *MCP Connectors* menu along with a '\+' icon in the prompt panel. Your application users can connect to a tool pre-configured by your ThoughtSpot administrator directly from the Spotter 3 prompt interface using the '+' icon and add resources to their conversation context.
+
 [NOTE]
 ====
-When customizing icons, ensure that the SVG hosting server is added to the CSP allowlist on the *Develop* > *Security Settings* page. For more information, see xref:customize-icons.adoc#_update_allowlists_in_security_settings_page[Customize icons].
+The MCP connector module and the '+' icon are displayed by default if the new prompt interface is enabled in your embed. However, we do not recommend using this feature in your production environments.

-==== Customize text strings
-To replace text strings, you can use the `stringsIDs` and `strings` properties in the content customization object.
-
-The following example shows how to replace "Spotter" and other text strings on the Spotter interface.
+Currently, the Visual Embed SDK does not provide any attributes or action IDs to hide these elements. As a workaround, you can use the CSS selectors to hide these elements:

+=== Customizing styles and interface elements
+The visual Embed SDK provides a comprehensive style customization framework for overriding icons, text strings, and the appearance of UI elements.
+
+The `customizations` object allows you to add custom CSS definitions, replace text strings, and override icons. If your customization framework uses external sources or hosting servers, ensure they are added to the CSP allowlist. For more information, see the xref:css-customization.adoc[CSS customization framework], xref:customize-text-strings.adoc[Customize text strings], and xref:customize-icons.adoc[Customize icons] sections.

 [#SpotterCSS]
-==== Customize styles
+=== Customize using CSS variables
+You can customize the background color of the conversation and prompt panels, button elements, and the components of the charts generated by Spotter using xref:customize-css-styles.adoc[CSS variables].
 
-There are several CSS variables available for customizing Spotter interface. You can customize the background color of the conversation and prompt panels, button elements, and the components of the charts generated by Spotter.
+If Theme Builder is enabled on your ThoughtSpot instance, you can find the variables for Spotter customization by navigating to *Develop* > *Customizations* > *Theme Builder* in the ThoughtSpot UI and downloading the CSS variables.
