+# Video Resource Server
+
+Demonstrates serving binary content (video) via MCP resources using the base64 blob pattern.
+
+## Quick Start
+
+```bash
+npm install
+npm run dev
+```
+
+## Tools
+
+- **play_video** - Plays a video loaded via MCP resource
+  - `videoId`: Choose from various sizes (`bunny-1mb`, `bunny-5mb`, `bunny-10mb`, etc.)
+
+## How It Works
+
+1. The `play_video` tool returns a `videoUri` pointing to an MCP resource
+2. The widget fetches the resource via `resources/read`
+3. The server fetches the video from CDN and returns it as a base64 blob
+4. The widget decodes the blob and plays it in a `<video>` element
