+  ### This week: Ads MCP, broadcast events, and new endpoints
+
+  **New features**
+
+  - **X Ads MCP server**: We launched the [Ads MCP](/x-ads-api/mcp), a remote MCP (Model Context Protocol) server at `https://ads-api.x.com/mcp`. Any MCP-capable client, such as Grok or Claude Code, can now read campaign data, run analytics, and manage campaigns through natural language using 23 X Ads tools. Access is scoped to your own OAuth 2.0 token, and campaigns and line items are always created `PAUSED` so nothing spends money until you activate it. See the [tool reference](/x-ads-api/mcp/reference).
+  - **Broadcast events in the X Activity API**: We added `broadcast.start` and `broadcast.end` events to the [X Activity API](/x-api/activity/introduction). Subscribe by User ID to be notified in real time when a user starts or ends a live broadcast. Both are public events, so you can subscribe with either app-only or user-context authentication.
+  - **Credit balance endpoint**: The new [`GET /2/usage/credits`](/x-api/usage/get-usage-credits) endpoint returns your developer-platform credit balance in USD, so Pay-Per-Use developers can monitor remaining credits programmatically.
+  - **Delete Chat messages**: The new [`POST /2/chat/conversations/{id}/messages/delete`](/x-api/chat/delete-chat-messages) endpoint deletes one or more messages from a Chat conversation. You can delete a message for all participants or only from your own view.
+
+  **Updates**
+
+  - **New web conversion metrics in Ads Analytics**: We added eight metrics to the `WEB_CONVERSION` metric group of the [X Ads API Analytics endpoints](/x-ads-api/analytics), including `conversion_add_to_carts`, `conversion_checkouts_initiated`, and `conversion_landing_page_views`. We also added a `CONVERSION_TAGS` segmentation type, compatible with the `WEB_CONVERSION` metric group only.
+  - **Higher pay-per-usage Post cap**: The monthly cap for pay-per-usage plans increased from 2 million to 3 million Post reads. See [Usage and Billing](/x-api/fundamentals/post-cap).
