+# Changelog
+
+All notable changes to this plugin will be documented here.
+
+## 1.0.0 — initial release
+
+- Added the `x-ads` MCP server pointing at `https://ads-api.x.com/mcp`.
+- OAuth user sign-in using X's client ID `NGdZYmo4VVp2T1BnRG55NlExOGQ6MTpjaQ` (the same client the X connector uses), requesting `ads.read`, `ads.write`, `media.write`, and `offline.access`.
+- Separate plugin from X: `ads-api.x.com` is a different protected resource than `api.x.com` with different scopes, so it requires its own authorization.
+- Logo: X's official mark from the X brand toolkit, on a black tile matching X's own app icon.

+# X Ads
+
+Cursor plugin that connects agents to the [X Ads API](https://docs.x.com/x-ads-api/introduction) through X's official hosted [Model Context Protocol](https://modelcontextprotocol.io/) server at `https://ads-api.x.com/mcp`.
+
+This plugin signs you in with OAuth as your own X account and works with the ads accounts you can access. Agents can manage campaigns, create ads, set up pixels and conversion tracking, and pull performance stats.
+
+This is a separate plugin from the [X](../x/) plugin: the ads MCP server lives on a different subdomain (`ads-api.x.com` vs `api.x.com`) and requires different OAuth scopes, so it needs its own authorization. Installing both means signing in twice — once per plugin.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **X Ads**.
+3. Click **Install**, then complete the OAuth sign-in when prompted.
+
+Or run `/add-plugin x-ads` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "x-ads": {
+      "type": "http",
+      "url": "https://ads-api.x.com/mcp",
+      "auth": {
+        "CLIENT_ID": "NGdZYmo4VVp2T1BnRG55NlExOGQ6MTpjaQ",
+        "scopes": [
+          "ads.read",
+          "ads.write",
+          "media.write",
+          "offline.access"
+        ]
+      }
+    }
+  }
+}
+```
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Accounts | Read your ads accounts, funding instruments, and settings |
+| Campaigns | Create, update, pause, and read campaigns and line items |
+| Ads & creatives | Create and manage promoted ads and creatives |
+| Audiences | Read and manage targeting and audiences |
+| Pixels & conversions | Set up the X pixel and conversion tracking |
+| Analytics | Pull campaign, line item, and ad performance stats |
+
+## Setup
+
+No token to paste — the plugin ships with X's OAuth client ID (the same one the X connector uses) and requests the scopes below. On first use, Cursor opens a browser window where you sign in to X and approve access. The `offline.access` scope lets Cursor refresh the session automatically, so you only sign in once.
+
+Requests run in your user context against the ads accounts your X account can access. You can revoke access at any time from your X account's connected apps settings.
+
+## Scopes requested
+
+`ads.read`, `ads.write`, `media.write`, `offline.access`
+
+## Docs
+
+- X Ads API: https://docs.x.com/x-ads-api/introduction
+- OAuth protected resource metadata: https://ads-api.x.com/.well-known/oauth-protected-resource
+- Authentication overview: https://docs.x.com/fundamentals/authentication/overview

+Logo is X's official mark from the [X brand toolkit](https://about.x.com/en/who-we-are/brand-toolkit), placed on a black tile matching X's own app icon.
